Oil & Gas Pipe Fabrication

High-Yield Cutting and Bending for Rig and Pipeline Infrastructure

The oil and gas sector operates under some of the most unforgiving regulations in the world. Refinery piping, upstream drilling manifolds, and overland distribution pipelines must withstand corrosive sour gas, high temperatures, and extreme internal pressures. Standard workshop machinery cannot cope with the high-yield, heavy-wall alloys used in this industry.

Critical Industry Requirements

· High-Strength Alloys: Processing heavy-wall carbon steel (like API 5L grades) and duplex stainless steels requires machines with extreme structural rigidity.

· Perfect Weld Prep: Pipelines depend on flawless welds. Any variation in the cut angle or tube end roundness slows down pipeline assembly and introduces structural risks.

· Severe Duty Cycles: Midstream and downstream fabricators need equipment that can cut and bend heavy components 24/7 in harsh workshop environments.

Wonsten Engineered Solutions

Industrial Dual-Column Metal Band Saws

Wonsten builds high-capacity, semi-automatic and fully automatic dual-column band saw machines that handle heavy-wall pipes and structural beams easily.

· Vibration Dampening: Rigid dual-column design eliminates blade vibration, resulting in a perfectly square cut and extended blade life when sawing tough alloys.

· Laser Alignment Guides: Built-in laser positioning guarantees high precision on heavy cut-off lengths.

Heavy-Duty CNC Pipe Bending & End-Facing

For short-radius pipeline elbows and manifold links, our heavy-duty CNC benders deliver repeatable results without degrading the material structure. Following the bend, our CNC machining centers or specialized end-facing setups cut precise weld bevels on the pipe ends, making them ready for immediate field welding.
