Submarine Pipelines

Different from land project,the products of submarine pipeline projects need to comply with API SPEC5L specifications,which is much higher than that of above-ground pipelines.Because of the special environment of the sea bed,if fuel leakage occurs,it is much more difficult to maintenance and the damage caused is much worse than that on land.In the API APEC5L specifications,seamless steel pipes and welded steel pipes of various steel grades are provided,including manufacturing process and materials,chemical and physical property requirements,test methods and standard dimensions.For example,in this specification,it is required to carry out factory inspection hydrostatic test for each pipe,and different sizes of pipes are required to have different test times.Our products are produced in such a series of regulations and inspections,and finally serve customers perfectly.
