Production:
The production of SSAW (Spiral Submerged Arc Welded) pipe is a highly advanced and efficient process that involves the use of specialized equipment and skilled professionals.
The production process of SSAW pipes involves the use of a coil of steel strip that is uncoiled and fed into a forming machine. The strip is then shaped into a spiral, and the edges are welded together using a submerged arc welding method. This welding method involves the use of a flux that creates an arc between the electrode and the steel, producing a highly durable and strong joint.
After the welding process, the pipes are inspected and tested to ensure they meet the necessary quality standards. The testing process involves various tests, such as hydrostatic testing and ultrasonic testing, to ensure the pipes are free from defects and can withstand the required pressure.
Once the pipes have been inspected and tested, they are then treated with a rust inhibitor and coated with an epoxy coating to protect them from corrosion. The pipes are then cut to the required length and packaged for transportation to the customer.
Advantages: Durability, strength, and ability to withstand high pressure and temperature, Can be produced in longer length(maximum length up to 50 meters) compared to LSAW steel pipes, Due to its spiral seam SSAW pipe has an accurate diameter accuracy and strength, The size are adjustable and can be tailored to end-user requirements
Application: Pipe piles, Bridge pillar, Public infrastructure and general structure support pipe, Drilling pipe, Oil and gas pipeline, Water supply and drainage pipe, Equipment machine made pipe,The transportation of petroleum and natural gas, Construction industry, Manufacturing industry
