PVC is made of vinyl chloride monomer (VCM) polymerization, PVC material with non-toxic, anti-aging and acid and alkali characteristics, it is very suitable for the use of chemical pipelines, PVC raw materials to join the production of solid agent Out of the product, known as UPVC (hard polyvinyl chloride).

UPVC pipeline system is resistant to impact, not easy to deformation, the wall is smooth, easy to scale, good insulation properties, the bonding of the convenience of cold glue, and long service life and other characteristics, so cost-effective and low-cost advantage has replaced other metals UPVC pipeline system is the first choice for the design of industrial piping. The UPVC pipeline system is the first choice for the design of industrial piping, and it is easy to repair and maintain quickly. It is unnecessary for long time downtime maintenance to cause huge losses.
