Description
Double Wall bellows is a new type of lightweight pipe made of high-density polyethylene. It has the characteristics of light weight, high pressure resistance, good toughness, fast construction and long service life. Its intentional wall structure design and other structures Compared with pipes, the cost is greatly reduced. And because the connection is convenient and reliable, it is widely used at home and abroad. A large number of alternative concrete pipes and cast iron pipes.
