Cangzhou Enfei Pipe Equipment Co., Ltd. is an excellent pipe prefabrication production and manufacturing enterprise in China. Pipe prefabrication is widely used in modular construction such as ship construction, petrochemical industry, power plant pipeline and natural gas pipeline. Due to the convenience of pipe prefabrication installation, short construction period, convenient welding heat treatment and inspection, it is favored by many engineering projects.
Pipe spools are fabricated from a number of raw pipes and pipe fittings (e.g. elbows, flanges, tees, etc.) in fabrication shops. Raw pipes are cut to the required sizes and moved with pipe fittings to a fitting table, where some of the components are fitted together (i.e. temporarily connected). The resulting sub-assembly (part of the final pipe spool) continues with welding operations (i.e. permanent connected) before it comes back to the fitting table and gets fitted with other spool components.
