What is Prefabricated Items ？

Prefabricated pipe fittings refer to pipeline components produced through standardized production in factories, which can be directly used for installation or can be put into use with simple processing.  ‌

Common types
Prefabricated pipe fittings include reinforced concrete pipe fittings, polyurethane insulation pipe fittings, ductile iron pipe fittings, etc., which are widely used in municipal, construction, water supply and drainage and other fields.  ‌

core features
Standardized production: Complete cutting, welding, assembly and other processes in the factory to reduce on-site construction time.  ‌
Various materials: such as seamless steel pipe, nodular cast iron, polyurethane foam, high-density polyethylene and other materials, suitable for different media and scenes.  ‌
Supporting standards: For example, the "Standard for Prefabricated Insulated Ductile Iron Pipe fittings" (GB/T 43492-2023) specifies parameters such as size, material, and performance.  ‌

Application scenarios
Municipal engineering: Cement components and insulation buried pipe fittings are used for underground pipeline systems.  ‌
Industrial transportation: Polyurethane insulated pipe fittings are suitable for insulation transportation of media such as hot water and steam.  ‌
Building support: Reinforced concrete prefabricated components are used for building structures or road facilities.  ‌
