Production process of ship pipe
In the ship pipeline system, pipes are indispensable. Today, Haihao takes you to see the production process of ship pipes.
Blanking: prepare, draw lines and cut pipes according to the cutting schedule. According to the pipe manufacturing process, allowance can be added to the theoretical length, which is called blanking with allowance; Blanking can also be performed according to the theoretical length, which is called blanking without allowance.
Elbow: bend the pure elbow or mixed elbow according to the pipe part drawing, and the straight pipe or shaped elbow shall be assembled directly into the pipe calibration process.
Pipe calibration: assembly of connectors, branch pipes, double plates, instrument joints, stoppers, pipe accessories, etc. on pipes.
Welding: welding of pipes.
Trimming: remove burrs, welding slag, sagging, etc. left on the pipe surface during pipe fabrication and welding, and repair unqualified welds mechanically.
Hydrostatic test: Hydrostatic strength test shall be carried out for the pipes after assembly and welding, and acceptance and submission shall be carried out as required.
Surface treatment: the pipe surface shall be galvanized, pickled, phosphatized, plastic coated, rubber lined or derusted and painted according to the drawing requirements.
Sorting and warehousing: sort out according to the pallet management table, and hand over to the distribution center after the number of tubes on each pallet is complete.
Phased installation: according to the principle of intermediate product oriented and integrated construction of hull, outfitting and painting, the installation of pipes and outfitting is interspersed in the construction of ship structures, which can be divided into unit assembly, subsection (forward and reverse) pre assembly, basin outfitting, general assembly (forward and reverse) outfitting, and shipway (dock) outfitting.
Phased installation is actually the process of prefabrication. After the completion, the pipes are basically processed in the factory, and then sent to the ship for installation. Haihao Group has participated in the pipeline supply of many FPSOs and various ships, and has rich experience in the production and prefabrication of ship pipelines. Our products are complete, including flanges, steel pipes, pipe fittings, elbows, tees and other products. At the same time, Haihao has advanced welding equipment, which can successfully complete the prefabrication task. If you have related projects to cooperate with, you can be assured to choose us.
