S.S.一种W pipe

S.piral submerged arc welding(SSAW) is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding, and welding them into a spiral.

What Are the Advantages of SSAW Pipes

• S.S.一种W steel pipe 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
• 尺寸可调，可根据最终用户要求定制。

标准

S.S.一种W steel pipe is made up of hot-rolled coiled steel using a double-sided submerged arc welding method. The welding process allows steel pipe manufacturers to produce large-diameter steel pipes suitable for different applications.

S.piral Submerged-arc Welded Quality Assurance

通过浸没电弧法生产螺旋焊接管道基于使用串联焊接技术，用于连接内部和外部线圈边缘，通过碳化物研磨以进行高质量焊接结构的碳化物研磨。

Listing some notes You must know

• Oiled marking:S.teel after passing wrer oiled to prevent corrosion,and according to user requirements for making.
• 平整铣削：The flat steel anvil machine so that the origal curl,and then thouth the edge milling machine for two-sided steel milling,so as to meet the requirements of the plate width,plate edge parallelism and groove shape.
• S.hear molding:The steel plate production line along the outer edge of the spiral curl into a tube.
• B.utt cut:Double-sided submerged arc welding using advanced technology to pre-welding,internal welding,outside wilding.The welded steel pipe using a plasma-foot cut to specification length.

Note:

Welding of hot rolled steel coils takes spiral form after passing through preforming and forming rolls. Excellent exterior weld quality at high production speeds is provided by double submerged arc welding process. Manufactured pipes are cut to the desired lengths at the exit of the pipe machine. Pipe ends are beveled by means of carbide machining for accurate on-site welding.

在管道输送到静水测试和离线超声波检测和/或实时X射线检测后，管道将受到最终检查的符合客户要求。

从进入控制到最终检查阶段的开始;通过计算机系统监控和支持整个过程。通过整个生产线的输入控制和条形码实现可追溯性。
