Decoration Guide: Family room decoration how to buy PE pipe
Decoration is a family event, if in the process of being deceived, even if the small house decorated, luxurious and then not liking to live together. Many consumers before signing the contract and does not understand the situation, but designers usually, "You do not ask, even if you know." Meanwhile, the home-improvement package is difficult to meet the personalized decoration, and a fixed main material brands and styles, choose the degree of freedom is not high. Specifically for your home life Xiaobian integrated to a variety of home improvement information, introduction of home decoration guide series, arranged for you out of one of the most romantic love nest.
Aluminum-plastic composite pipe: plastic composite pipe loss is small, coil easy to transport, can be an arbitrary cut, easy to install, easy construction. However, parts of copper and expensive, copper pieces inside diameter smaller than the aluminum-plastic composite pipe diameter, caliber flow is small, and easy to install bad case of leakage of thermal expansion and contraction. Pipeline construction process vulnerable to the destruction of other professionals, to waste repair parts, high cost. Plastic pipe is made of high density polyethylene clip aluminum, polyethylene, the melting point of 140 ℃, so the long-term high-temperature performance, good use of their matching card sets of nuts and steel sleeve-type clamp pressure pipe fittings, if properly installed, high degree of reliability.
PP-R pipe: PP-R pipe has been building water sector as a green, reliable pipe. PP-R pipe PP-R pipe fittings are also material, as compared with the aluminum-plastic composite pipe, low cost, and the pipe installation is set out in the pipe, resulting in diminished flow. However, PP-R pipe should not be vacant long, every 50cm or so to set up a fixed bracket, or easy to sag, bending. In addition to pure PP-R pipe outside, and now there is a PP-R aluminum-plastic pipe, this pipe fittings PP-R pipe with the same, but the equivalent of aluminum-plastic tube performance, cost less than the aluminum-plastic composite pipe, and the anti-aging and strength of better performance, long-distance vacant does not sag, bend.
It is understood, PP-R pipe itself due to the molecular characteristics of polypropylene, whether imported or domestically produced, there is poor performance and high-temperature linear expansion coefficient and other shortcomings. Therefore, the Ministry of Construction [2001] Document No. 54, years, PP-R pipe expressly provides long-term working temperature should not exceed 70 ℃; while its hot melt-type connection process is more complex when you push the pick is easy to produce material defects in the heap area, leading to stress concentration, affecting the pipeline long-term performance. Therefore, the time of purchase, do not easily or with no qualification commission hydraulic fitting company, purchase products to pay attention to the actual place of origin, trademarks and service guarantees.
PE pipe: PE pipe structure of a single, integrated performance is less than aluminum pipe, mainly used to warm water, floor heating facilities generally do a good job by the builders, and home decoration are normally less than PE pipes.
PVC-U pipes: PVC-U pipe connection for the adhesive, easy to fall off when you opened the event of hot glue, only applies to Buried underground pipeline or pipelines, if used in large-diameter high-pressure-ming, pipes, must be designed a special bracket, in particular, is a corner site, the impact of water damage on the corner great. Decoration when the water is not recommended to use PVC-U pipe, but the threading tubes are generally flat flame-retardant PVC plastic pipe (PVC pipe threading).
Copper: Copper's health superior performance, but the cost is high. Copper tube connections are welded (sub-band tube with a tin tin, not two), pipe fittings card access (two types of pipe fittings, one is a clip-style, one is inverted teeth bite, rubber ring seal) . The follow-up pipeline construction easily be damaged or re-decoration. "I love my home" Tip: family decoration often overlooked diameter water supply pipe and the choice of staying after it was found that a lot of problems, such as leaking pipes damaged decoration, not enough water pressure, water heaters can not start and so on. Therefore, from the life of pipe to consider the best choice for good quality of copper pipe or aluminum-plastic composite pipe, Diameter should be 20 mm or more, to connect a faucet manifold can not be less than 15 mm, or inadequate water pressure and water flow will occur noisy faults. If you choose aluminum-plastic composite pipe cassette accessories, should pay attention to their diameter and increase the actual diameter of 2-3 mm options, such as the branch pipe diameter 2025 specification, but should be in charge of the 2532 specification, in order to ensure that more than two taps at the same time water when the amount of water.
Pipe: To meet the health needs of the various health indicators, water must meet the national standards to be used. However, the cleanliness of the water pipe is not entirely dependent on water quality pollution depends on the pipe can withstand the outside air, the oxygen penetration to the wall. A long-term oxygen penetration easy to make pipe breeding of bacteria, scale, long moss, which pollute the water. Experts suggest the purchase of household plastic pipe, it is best to ask for product quality inspection report on business, do not plan to purchase cheaper no name and address of the pipe. |
