Many places in China have attached great importance to the construction of underground pipe corridors, and the area completed and put into use has increased year by year, in recent years, the government work report and the central meeting have specifically mentioned accelerating the construction of urban underground pipe corridors.  How can the construction of urban underground pipe corridors further reduce costs? Many people think of stainless steel and carbon steel composite pipes. Previously, many people and even many experts simply understood that perhaps the composite pipe of stainless steel and carbon steel was the only way to reduce costs. On the contrary, given that stainless steel is already very cheap, the composite plate or composite pipe of stainless steel and carbon steel can not reduce the cost much, not only the composite process requires cost, but also because the anti-corrosion treatment of carbon steel surface needs to cost more. (In addition, in recent years, FRP composite pipes have also been favored by users with excellent comprehensive performance and high cost performance.) ）

On the morning of May 4, 2023, Li Qiang, executive president of Sichuan Chuanlian Stainless Steel Industry Chamber of Commerce (executive chairman of Foshan Metal Materials Industry Association and executive chairman of Hainan Stainless Steel Industry Association), accompanied by Secretary General Luo Jihao, went to Chengdu Joint Pipe Group Co., Ltd., a member of the stainless steel water pipe high-end forum, to visit Chairman Chen Mo and General Manager Chen Gongli, and asked for advice and exchanged topics such as the continuous acceleration of the popularization process of stainless steel water pipe application.

During the period, Chairman Chen once again introduced to Chairman Li in detail the medium and large diameter glass fiber reinforced stainless steel composite pipe developed by the joint pipe industry, and two samples were placed in Chairman Chen's office. Fiberglass reinforced stainless steel composite pipe not only solves the corrosion problem of stainless steel and carbon steel composite pipe, but also reduces the cost of 304 or 316 stainless steel welded pipe. It is understood that the joint management industry has applied for a patent and is developing relevant standards. Once fully promoted, it will inevitably add the application options of corrosion-resistant pipes, which will obviously accelerate the application and popularization of stainless steel pipe galleries around the world.
