Oil & Gas Transport Φ355×14 Pipe Mill (API Pipe Mill)

Short Description:

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

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

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

4. Wide Applicability: Ideal for single seam straight seam welded pipe ranging from Φ89 to Φ273 with thicknesses up to 12mm, ensuring extensive usage and adaptability.

Product Detail

PRODUCT MODEL LIST

Product Tags

Long-distance oil and gas pipelines are hailed as the “main arteries” of energy transportation, and welded pipe manufacturing technology is rapidly developing towards higher steel grades, larger diameters, higher toughness, and intelligent manufacturing.

API line pipes refer to industrial pipelines conforming to the API SPEC 5L standard set by the American Petroleum Institute (equivalent to GB/T 9711 in China). Their main purpose is to transport oil, natural gas, and petroleum fractions from extraction sites to processing plants or end users. Welded pipe production lines are specialized production equipment for API pipes.

In the field of long-distance oil and gas transportation, welded steel pipes hold an absolute dominant position. This pipe-making machine mainly refers to a high-frequency resistance welded pipe (ERW/HFW) production line.

Raw materials:

Hot-rolled or cold-rolled steel strip.

Core process:

Utilizing the “skin effect” and “proximity effect” of high-frequency current, the edges of the pipe blank are instantly heated to a molten state, and pressure welding is achieved under the action of extrusion rollers.

Applications:

Widely used in urban gas pipeline networks, gathering and transmission pipelines, and structural pipes. In recent years, thick-walled, high-strength ERW pipe technology has also been continuously developing.

Compared to ordinary pipe-making machines, API welded pipe production lines include the following additional processes:

Non-destructive testing (NDT): Standard configuration includes ultrasonic testing (UT) and eddy current testing (ET). High-end products utilize automated ultrasonic testing (AUT) and real-time X-ray imaging, achieving a defect detection rate of over 99.9%.

Hydrostatic testing: Every steel pipe must undergo a hydrostatic test, a mandatory requirement of API standards that cannot be replaced by NDT.

Weld treatment: Internal burrs must be removed until flush with the base material (remaining height not exceeding 0.5mm). External welds must have a smooth transition to prevent cracking of the anti-corrosion layer.
