What are the advantages of PVC-U?

As the Ministry of construction in 1996 to promote scientific and technological achievements, the rigid PVC PVC drainage pipe of this new chemical building materials because of its good physical and chemical properties, easy installation, etc., has been widely used in the domestic and international construction projects. PVC drain pipe in the engineering use of cast iron pipe unparalleled superiority.

1, good drainage performance

According to the calculation of water ring membrane theory of gravity, drainage water film flowing through the flow area of not more than vertical pipe break area 1 / 3 to 1 / 4, plastic vertical tube drainage of the maximum discharge capacity than cast iron pipe increased by 60%, and not the destruction caused seal. Therefore, for the same equivalent amount of drainage, PVC drainage tube diameter can than cast iron pipe diameter is small, or the same diameter in the specification within the scope of license can be as much as possible with smaller slope, which can increase the height of space, to the user is more favorable, enhanced the use function of the building.

2, superior physical and chemical properties

PVC pipe is thermoplastic products, by PVC heating into molten state (200 ~ 150), with 56% unique flame retardant elements chlorine (Cl), so oxygen index is high, is difficult to burn, chemical properties, specific mechanical physical properties make it normal use for 50 years, and its anti corrosion, anti aging, wear resistance also make it more than the drainage cast iron pipe, cement pipe more long-term stability, so as to reduce the cost of operation and the natural loss of materials, is conducive to the long-term use of buildings, but also increased the use of building safety and reliability.

3, economic, beautiful

According to the current market situation, the price of PVC drainage pipe is only about 80% of cast iron pipe, that is, the cost per thousand square meters per thousand square meters of construction cost savings compared with the cast iron pipe cost reduction of about 700 yuan. In addition, because the PVC pipe is lighter, the transportation cost can be reduced obviously.

PVC drainage tube usually outer wall is white, and not as paintbrushes Hongdan, silver and anti-corrosion treatment, such as cast iron pipe wall corrosion off problem does not exist, the dark into the tube wells without frequent maintenance and care, bright outfit is than the cast iron pipe advantages is more significant: easy to clean, on the visual effects interfere with less, which has greatly improved people's living, working environment, also facilitate the buildings on the property management.

4, pipe light, convenient construction

For a long time, the drainage cast iron pipe due to a large proportion, and the installation of the need to play Ma, modulation interface materials, twisting, maintenance, construction is not only heavy work, and the installation time is very long, so that the construction efficiency is significantly reduced. And PVC drainage pipe pipe proportion is about 3 which has, only cast iron pipe of L / 5, the plastic pipe of the same length to than cast iron pipe is much lighter, when installation manual handling and PVC drainage pipe uses is socket type solution viscosity interface, at the same time, the standard length (4m, 6m) than the cast iron pipe, reducing the number of interfaces, reduce the installation process. For example: a standard DN110 long 6m plastic tube only one person can be installed, and cast iron pipe to 2~3 people, so that the installation time can be reduced by more than 50%, the installation cost can be reduced by more than 60%, for the construction unit, can save money, reduce costs, shorten the project cycle, but also improve the economic structure of the building.

5, good social benefits

In China's steel supply becomes more and more scarce today, PVC drainage pipe can be in a wide range of alternative to other steel drainage pipe, but also greatly reduce energy consumption in the process of steelmaking, and price this procedure caused by environmental pollution. Have good social benefits.
