News - API pipe making machines

Large-scale API pipe-making machines generally refer to units producing large-diameter, thick-walled pipes with an outer diameter ≥ 273mm (10 inches), specifically designed for long-distance oil and gas pipelines and pressure steel pipes for oil fields.

API: American Petroleum Institute standard

Compared to ordinary civilian welded pipe units, the entire production line is enhanced in terms of forming rigidity, welding power, heat treatment, non-destructive testing, and hydrostatic testing to meet the requirements of high-pressure, high-strength pipelines.

It can produce high-grade steel pipes such as X42/X52/X60/X65/X70.

ZTZG independently developed, designed and produced an automated round welded pipe production line without changing the roller.

✓

During the production of Round pipes of different specifications, the moulds for forming part are all shared and can be adjusted electrically or automatically.

✓

The moulds for sizing part need to be replaced by the side-pull trolley.

Process characteristics：

Complete Roller Sharing: When producing different sizes of round pipes, all forming section roller are shared, significantly lowering your overall investment costs.

Electric and Automatic Adjustment: Effortlessly switch pipe sizes with electric or automatic adjustments, greatly reducing roll change time.

Efficient Roll Changes: While the sizing section roller require replacement from the top, this process is quick and straightforward, especially with backup rolls.

Wide Applicability: Ideal for single seam straight seam welded pipe ranging from Φ140 to Φ711 with thicknesses up to 25mm, ensuring extensive usage and adaptability.
