Prefabrication Piping Spools

Prefabricated Pipe Spools are made of pipes and fittings (such as elbows, flanges, tees, reducers, etc.). It is welded from steel pipes, fittings, elbows, reducers, flanges and other parts of various pipelines, so that customers do not need to spend more personnel,production and testing equipment on the project site, which greatly reduces the cost of industrial engineering projects such as the oil and gas industry.

 

 

 

JN ALLOY has professional and mature experience in custom production of prefabricated welding products, and can customize various welding products according to customer drawings and needs. We have successfully customized prefabrication products of materials such as 304, 316, 254SMO, 2205 for customers many times.

All production standards comply with the American Society of Mechanical Engineers ASME ASTM and other international standards, or other standards required by customers to ensure that the product quality is 100% in line with the requirements. Radiography, PMI, MPI, ultrasonic testing, water pressure testing, etc. can be carried out under the strict supervision of third-party(BV,SGS etc.)inspection agencies.

 

Now more and more industrial construction projects such as oil refineries, chemical plants and power plants are beginning to tend to use steel pipes and fittings as raw material parts welded together and then installed on site. Customized Prefabrication Pipe Spools is a better cost-saving option.
