pvc pipes

Description

1, Corrosion resistance, impregnable from corrosion soil and various kinds of water for life, high performance to inorganic acid, alkali, salt in corrosion resistance, suitable for excellent industrial sewage discharge and transportation. 
2, Ageing resistance and long service life, and the normal service life is about ****0 years, it is the building drainage, sewage ideal materials. 
3, Shock resistance is strong, high mechanical strength. 
4., Not easy to clog, not fouling, smooth inside, small fluid resistance, roughness coefficient is 0.**9, unhindered stream, little maintenance . 
5, Not out of the rust water, ensuring external rust won\'t because of pipeline rust and pollution, resist the oxygen index is high, with self-extinguishment. 
6, Light weight, for iron pipe 1/*0, handling and installation are convenient, comparing to cast iron pipe improve efficacy *0 *- *0%, obviously reduce project cost. 
7, Pipeline\'s swell factor is small, thermal conductivity and elastic modulus are small, and it has excellent drain freezing resistance performance compared with iron pipe.
8, Using unique auxiliary , making the product not issuing a pest love of odour, avoid termites, pest biting damage. 
9, Great variety of goods, can cooperate with various design and installation standard.
