Production Process

 Shengji deep well api 5ct p110  n80 casing and tubing steel pipe

1.Outsourcing flat end tube

After purchasing the flat-end pipe into the factory, we strictly inspected the purchased flat-end pipe according to the requirements of the company's incoming inspection. Inspection items should include tensile properties, hardness, chemical composition, impact properties, grain size and inclusions, geometry, straightness, appearance.

2.Upsetting

The upsetting production line is fully automatic control, with reliable performance and advanced technology. The performance index of the equipment has reached the domestic advanced level, and the steel pipe can be upset from 2 3/8in to 5 1/2in, which lays a solid foundation for ensuring the quality of the tubing.

Tubing Upsetting Production Line
