How is LSAW pipe made in the UOE Method?
The manufacturing journey of our LSAW pipes is a blend of cutting-edge technology and meticulous attention to detail. The process begins with the UOE and JCOE forming methods. In the UOE method, steel plates undergo pre-bending, U forming, and O forming, using dedicated forming presses. This sequential deformation transforms the steel plate into a circular tube. On the other hand, the JCOE method involves a series of stamping steps, where the steel plate is shaped into “J”, “C”, and “O” forms, resulting in an open “0”-shaped tube blank. At UNIACERO, every step is monitored closely, ensuring that the final product stands as a testament to our commitment to excellence.
How is LSAW pipe made in the JCOE Method?
The JCOE method of producing LSAW pipes is a testament to precision engineering. At UNIACERO, the process begins with stamping on the JC0 forming machine. The steel plate is first pressed into a “J” shape, followed by forming a “C” shape, and finally, pressure is applied from the middle to create an open “0”-shaped tube blank. This intricate process ensures that each pipe is crafted to perfection, offering unparalleled strength and durability. When you choose our LSAW pipes made using the JCOE method, you’re opting for a product that embodies excellence in every curve and weld.
What is the difference between LSAW pipe and SSAW pipe?
When it comes to choosing between SSAW and LSAW pipes, it’s essential to understand their distinct characteristics. LSAW pipes, which we proudly specialize in, offer a slight edge over SSAW pipes in several areas. Firstly, LSAW pipes have lesser residual stress, ensuring a more stable structure. The heat-affected zone in LSAW pipes is smaller, reducing potential weak points. In terms of accuracy, LSAW pipes excel, making installation a breeze. Moreover, the welding line of LSAW pipes is about 60% less than that of SSAW pipes, and their quality can be non-destructively tested. At UNIACERO, we prioritize your needs, ensuring that our LSAW pipes offer you the best in terms of quality, durability, and efficiency.
