Spiral Welded Pipe Machine SSAW Pipe Making Machine

Spiral Welded Pipe Machine SSAW Pipe Making Machine

The steel coils are unfolded and leveled by the mill equipment. And they are sent to the forming machine in a certain angle. Supplemented by a certain angle, the continual pipes are formed in the principle of three-roll rolling machine. Continual spiral welding is welded by submerged-arc welding machine. The uncoiling, coil detaching, leveling, steel cutting and welding are working on the fly-welding carriage. When the steel is welded, the fly welding carriage moves forward in the same speed with the host equipments. The host machine will not have the stop. After the steel welding finishing, fly welding carriage backs forward to the original position t wait another coil. This mode is called continuous production method with high efficiency, high pipe quality, rare welding repair and other advantages.

According to the different function of our products, the back swing spiral welded pipe mills are divides in to API model and standard model. API model mainly produces the delivery pipe with petroleum or natural gas (long distance), the material and quality of the steel pipe need to be very good. The requirements for mill equipment and testing equipment also are very high. The standard model produces the pipe used for short distance delivery of natural gas or water, the pipeline construction in the city, the structure pipe, column pipe and so on. The requirements for the material and quality of the steel also are very high.
