【 Weak current College 】 interior design of the selection

Abstract: interior designers usually focus on interior layout and decoration, as home "blood" in the pipeline is seldom a concern. Home decoration, for each family is a big investment. Home of quality event, nature is a top priority for consumer concern. General decoration they would have five years to ten years, some even longer, if the quality of the decoration of unhappiness, will give consumers bring endless troubles. The decoration in the pipeline, the renovation cost very little, are often overlooked. The following two ways about it:
A the health water, water is the source of life, human existence a moment away from water, the development of human society also automatically attaches to the rational use of water resources. It is a long history of pipeline engineering, glorious moment of Roman had a prototype of the drainage system, Sichuan Chengdu dujiang, ancient water irrigation, yellow car benefit Chinese people thousands of years. But in the modern sense of the city pipeline engineering, starting at the power of invention: electricity, water pump, it has made it possible for residential buildings.
With the progress of the social productive forces, "health" and "security" is the most emphasis on two major themes, drinking water quality and water security also became the focus of attention. From the quality assurance, the water company produce conforms to the standards of drinking water through water supply pipeline to millions of households, but the traditional pipe systems using a metal pipe, galvanized steel pipe, secondary pollution problem in the long-term is not resolved, the Terminal is difficult to guarantee the quality of drinking water. Why metal tube cannot guarantee water quality, and will produce secondary pollution? this is mainly due to the characteristics of metal pipes, easy rust, corrosion and leakage easy on and easy scaling can be said to be the four metal tube Achilles ' heel. Once the galvanized pipe, iron and air or oxygen chemical reaction in water, the pipes are rusty, and outside of the breeding range of microbial pollution in water pipes, these contaminated tap water-borne bacteria like invisible killer, threatens our health. Over the past 10 years, some foreign legislation or developed countries has established industry regulations prohibit the use of galvanized steel tubes as drinking water pipeline, and make full use of the plastic does not rust, corrosion-free, no leakage, no scaling quality green tubing, fundamentally resolve the water pipeline system of secondary pollution problems.
Prominent health performance makes the new plastic and plastic composite class building water pipes, such as PE pipe (PE), polypropylene (PP), polybutylene pipes (PB) and aluminum-plastic composite pipe (PAP), in recent years the rapid development in China, particularly in the regions in terms of water supply pipes disabled galvanized pipe, the sales increase faster. Due to the good performance of new plastic pipe is not available in traditional steel tube, water supply system by new plastic pipe replacement galvanized pipe has become a trend, irreversible. With the new plastic usage gradually strengthening, constantly learn new plastic pipe good overall performance, this kind of product penetration rate also increased substantially. According to the relevant departments of the Ministry of construction is expected by the year 2015, the country's new residential drainage within 85% use of plastic pipe, basic eliminated the traditional cast iron pipe, building supply pipe, hot water supply and heating pipe 85% use of plastic pipe. Basic urban water supply pipes out of galvanized steel, diameter 80% 400mm following use of plastic pipe, 90% of rural water supply pipeline adopts the plastic pipe.
Second, the pipe performance pipe materials selected first factor to consider is the use of pressure and temperature have sufficient mechanical strength, and the flow of the fluid has a good corrosion resistance, and includes the cost of materials and engineering.
Economic development and the improvement of living standards, the home environment proposed new requirements. Modern home view, from the past of a shelter to today's leisure, comfort, good transition. This requires modern home must have clear and bright visual perception and has a spacious and comfortable room, reflected in the bedroom decoration design, piping buried as requested. Pipeline laying of buried, is to beautify the home, make people stay pleasant premise of piping layout direction of development. Traditional pipeline, due to the easy rust corrosion, scaling and pipe plug, connector more prone to leakage, short life, so that it cannot lay buried, either use the health, or in the living room decoration, can not meet the requirements of the modern home. In recent years, building water pipeline system of rust to become an important topic, how different parts of the water supply situation, choose good piping systems, particularly for high-quality drinking water systems, choice of pipe material is an important aspect. To keep abreast of trends, beautification of the modern home, you must use the appropriate type of pipe to replace the traditional pipe to ensure good performance in the use of pipeline and long service life under implemented buried.
Pipeline materials once the quality is not good, led to the use of leakage, seepage. Its harm large and difficult to handle. Leaking while direct loss is relatively small, but often indirect economic loss is large, especially leakage occurred concealed plumbing, requires chiseling away closed pipe wall materials, repair after covering wall material color is hardly consistent with damage to the interior decoration effect. Main leaking water flows to the lower room, often lower ceilings, wall, floor decoration corrupted strict indoor water pipes material quality is critical.
At present, water supply and heating system of common pipe include stainless steel tubes, copper tubes, steel-plastic composite pipe (PAP), hard PVC pipe (PVC), cross-linked polyethylene pipe (PEX), polyethylene (PE) and polypropylene (PP), polybutylene pipes (PB), etc. Our water supply pipe has undergone a galvanized pipe, plastic and composite pipe process, are now phasing out and prohibition of the use of galvanized steel tubes. Currently has a variety of materials can be produced of pipes and fittings, such as a hard PVC pipes, PE and PP cross-linked PE pipe, tube and PP pipe, ABS pipe, aluminum-plastic composite pipe, steel-plastic composite pipe and tube, etc, can produce GRP pipe, fiberglass reinforced plastic pipe pipe and thermoplastic.BR > comprehensive consideration of various pipe performance, cost and life, and other factors, as well as drinking water health performance concerns, the current domestic popularity of aluminum-plastic composite pipe (PAP). Aluminum-plastic composite pipe combines the advantages of metal pipes and plastic pipes, the service life of 50 years, very suitable for home decoration in the pipeline, is a leader in numerous pipes.
Aluminum-plastic composite pipe welding by a middle-tier vertical aluminium tubes, inner and outer layer of polyethylene and of a melt between one-step co-extrusion, inner and outer layer of polyethylene is a symmetry of non-polar polymers, chemically very stable, with non-toxic, corrosion resistance, high mechanical strength, heat resistance, brittleness temperature low, long life and other characteristics, while the inner layer polyethylene very glossy, tube fluid resistance is small, non-scaling, enabling the effective diameter of the tube than metal tube and fluid will not be affected by pollution. Middle welding aluminum pipe layer in addition to strengthening the role played in polyethylene, pipe pressure resistance intensity greatly increased, and there are seven advantages: ① 100% oxygen, complete elimination of permeability; ② bending rebound energy absorption tube so that the tubes can be forming; ③ enhance the ability of longitudinal thermal, increase the flame effects tube, ④ lower tube, integrated thermal expansion coefficient, the dimensions of the pipe; ⑤ used as a stable communication lines of the shield, preventing all kinds of audio, magnetic interference; ⑥ has antistatic properties, available for the transmission of gas and oil; ⑦ metal detectors detect the location of burial.
Good piping materials must be easy to install. Aluminum-plastic composite pipe light weight, can bend without rebound, single tubes up to several hundred meters in length, to support the general building set meter settings, as well as single-tube to every household. The introduction of water supply pipes community, building the underlying the water separator, the water separator into the branch after every household water meter unified installation in the back of water separator, facilitate centralized management of meter reading.
Aluminum-plastic composite pipe inner diameter 10mm-60mm mainly from 10 kinds of specifications and three varieties of types: standard--suitable for potable water, pure water, compressed air, oxygen, chemical liquid, fluid conveying, medium temperature ≤ is 60 degrees centigrade, rated working pressure 1.0MPa; temperature resistance--suitable for hot water, space heating, high temperature fluid conveying, medium temperature ¡ü 95 ℃, working pressure rating; gas 1.0MPa--applies to town gas, LPG transport, medium temperature ≤ 40 ℃, working pressure 0.4MPa rating.
Aluminum-plastic composite pipe rated working pressure is higher than any existing organic pipes (for example: polyethylene, cross-linked polyethylene pipes, HDPE, polypropylene pipes, etc.). Wall roughness to 0.007mm (galvanized pipe 0.15mm ~ 4.0mm), due to the very smooth inner wall, transportation, water and other fluids resistance losses small, does not produce noise. Aluminum-plastic composite pipe health non-toxic, in full compliance with the national standard GB/T
17219 "drinking water transmission and distribution equipment and protective material safety evaluation standards". 3. Design and construction of some of the issues as a result of aluminum-plastic composite pipe (PAP) with coil packaging and quality advantages of a lighter, in recent years some manufacturers such as FOSHAN RIFENG Enterprise Co., Ltd. of scale of production and quality are increasing rapidly in the market to establish a good product image and brand awareness. As awareness of enterprise services, so that many users in the design and construction is always require the supplier to meet certain performance requirements cannot be met, so that in practice there are some issues that could have been avoided.
New plastic pipe is rapidly in recent years, some installation specification is not yet perfect, construction quality varied, often leaking phenomenon. These leakage phenomenon mostly decorated room, very rare in the project, mainly caused by poor quality construction. New plastic tubing, light weight, flexible (such as aluminum-plastic composite pipe), pipe connection easy, easy to cut, so often by non-professional operators set up, and after installation only pass water, very little to the hydraulic test, once the water supply network pressure fluctuations, it is easy to result in leaks. New plastic tubing suitable for dark, many indoor water pipes constant selection subsurface water etcl pretend, after plastering plaster closed pipes, House decoration, good effect. However, concealed water if you do not do is hidden to the hydraulic test, leakage damage wall surfaces required to repair.
New plastic pipes of large linear expansion coefficient than steel pipe, used for transportation of hot water needed to monitor expansion expansion compensation design. Engineering design of the user in the drawings are often considered, not a problem, but users often indoor hot tubs are useful because of the expansion and lead to leakage incidents.
There is also a phenomenon is the new plastic pipes from freezing climate cold impact damage leaking. In fact, currently the known types of applicable building water pipe insulation protection measures are not taken are frost damage leaking. The construction of water supply and drainage design code there is also a detailed requirements, "the article to the water pipe to 2.4.7 laying in the non-freezing room, such as laying in likely freeze, frost protection measures should be taken. The water supply pipeline do insulation protection, in China's Beijing in the North have the hearts of the people, is also very highly valued; South China, it is not possible to freeze also need not worry. Frozen water leakage phenomenon occurs mostly in the eastern regions of the provinces of Jiangsu, Zhejiang, East China area between North and South, belonging to the winter non-heating area, may be the ten year freeze, often missing insulation measures freezing pipes.
The development of a new plastic pipe quickly, related industries product standards and some are writing has not yet been published, there have been some product quality standards inconsistencies, especially supporting new plastic pipe of attachments (such as pipe fittings, valves, etc.) the quality of products has led to more black sheep, and the product quality problems resulting leakage, seepage accidents. Therefore, to the attention of the user in decoration, remember to buy the same brand of pipe and fittings.
Improper use of the user and caused leakage phenomenon has occurred from time to time, for example, indoor Ming installed water supply pipeline due to collision or fastening tubes card damaged pipe leaking; indoor concealed water pipeline because fixing the leaky pipes, etc. New plastic pipe stiffness ratio low original galvanized pipe, only for conveying water carrier, northern miningWarm tube user do stepping, Pan pipes, to open the Interior support upper window caused damage leaking pipes. The development of a new plastic pipe, prompting a number of manufacturers in the market competition that brand awareness, efforts to improve product quality and after-sales service. However, users use improper claim, also makes the new plastic pipe manufacturers more puzzles, new plastic pipe is in the last few years, in order to expand the market, the market won a good reputation, the manufacturer also frustrated. User abuse caused by water leakage is to be avoided are avoidable, a Government Department in charge of strengthening market management and technical standards, specifications, publicity; second, the product usage manual, details the use of the environment and considerations, etc.
