Threeway is an API 5L steel pipe, ASTM A53 pipe manufacturer. we are also able to produce A252 Pipe Piling 20 inch STD welded steel pipe. All our A252 Pipe Piling 20 inch STD carbon pipes are done ultrasonic test and all internal flash and external flash removed. Pipe quality and pipe surface is at top end.
Piling Pipe is widely used in coastal, river, lake area. In coastal area, there are large-scale construction for offshore deepwater terminal project which indecates large market needs for piling pipes. As the major deep water dorck pile bearing capacity, piling pipe is generally choose large diameter spiral welded steel pipes (SSAW Steel Pipes). In addition, piling pipes is widely used in bridges, roads, high-rise building ect.
Production of steel piling mainly use the double submerged arc technology. A first advantage of using the double submerged arc technique is completely automated; The second advantage is conducted under submerged arc welding, the heat exchange and protection of its relatively strong performance, high quality welding out; the third advantage is the automatic submerged arc welding arc welding flux can be used under high-current, high welding efficiency.
In order to ensure the quality and progress, to prevent damage to surrounding buildings, according to the intensity of the pre-piling pile, pile size, length and pile frame is easy to move and other factors to selec the correct piling order.
