In recent years, with the promotion and application of China's plastic building materials, the plastic pipe industry has developed by leaps and bounds. Our company has developed new water supply and heating pipes such as PP-R pipe, PP-R aluminum-plastic composite pipe and PE-RT floor heating pipe. The company now has ten polypropylene (PP-R) pipe production lines for hot and cold water, three PP-R aluminum-plastic composite pipe production lines, three PE-RT pipe production lines and eight tube injection molding machines. It can produce 25 million meters of PP-R pipe, 6 million meters of PP-R aluminum-plastic composite pipe, 10 million meters of PR-RT pipe and 500 tons of pipe fittings. In 2012, the company added five new PVC-U drainage pipe production lines, four insulated and flame-retardant electrical casing production lines and five pipe injection molding machines to produce PVC-U solid wall drainage pipes, pipe fittings, hollow spiral drainage pipes and electrical casings. At this point, "Antong" brand products have covered the construction of water supply and drainage, floor heating, electrical casing and other piping systems.
