Liaoning to promote buried steel-plastic composite spiral winding drainage pipe notification

In order to implement the provincial government's policy of maintaining growth, promoting new products such as energy-saving and emission reduction, and ensuring the quality of municipal drainage projects in our province, we hereby notify the relevant requirements in the promotion:

1. The steel-plastic composite spiral wound pipe developed by Liaoning Far East New Pipe Industry Development Co., Ltd. is a new type of energy-saving drainage pipe. The product has been scientific and technological achievements identified and put into production appraisal, and formulated the provincial local standard "buried steel-plastic composite spiral winding drainage pipe engineering" Technical Regulations dB21/T1626-2008, to promote the use of this product to make technical preparations. The use of such drainage products in the construction of municipal projects can prevent pollution of groundwater by drainage pipes. The product has good anti-corrosion performance, long service life, light weight, low flow resistance, convenient construction, and low overall construction cost. It is an application prospect. A vast new energy-saving drainage pipe.

2. In the construction of new, reconstructed or expanded municipal projects, the province must vigorously promote the use of such new energy-saving and environmentally-friendly steel-plastic composite wound drainage pipes.

3. The relevant units and departments for the design, construction, supervision, and project quality supervision of municipal engineering construction shall strengthen the energy conservation supervision of the construction of municipal drainage projects, vigorously promote the use of new energy-saving and environmental protection drainage pipes, prohibit the use of reinforced concrete pipes, and ensure the drainage of municipal construction. The project quality will actively protect the groundwater resources and environment for the benefit of future generations.
