ERW325 Advanced Technology High Frequency Straight Seam Steel Pipe Machine API Tube Mill
Product Details
This high-frequency welding pipe mill is specialized equipment to produce high frequency straight seam welded pipes for structural pipe and industrial pipe with Φ140mm~Φ325mm and wall thickness of 4.0~12.7mm. Through optimization design, best materials choice, and accurately fabrication and rolls, the whole line can be reached high precision and high speed. Within suitable range of pipe diameter and wall thickness, pipe production speed can be adjusted.
API pipe mill is specialized for manufacturing straight welded pipe for petroleum and gas pipelines. Taking hot-rolled steel as raw material, it produce required pipes through cold roll forming and suitable welding methods like H.F. welding, submerged arc welding and so on. The whole production line adopts ‘ZTF’ forming technology.
Technical flow
Scroll up → Uncoiler → Straightening end → Flattener → Auto-shear and welding → Horizontal accumulator → Strip UT → Forming(ZTF) → H.F. Induction welding → Removing external burr → Removing inner burr → Burnishing → Online detection → Seam annealer → Air cooling → Water cooling → Sizing → Cut off → Roll table → Flattening test → End-facing and chamfering → Hydrostatic test → Off-line UT test → Drifter → Inspection → Weighing and length measurement → Coating & printing → Packing → Warehouse
Usage
ERW pipe mill is used to produce API, EN,ASTM,GB/T etc pipe to transport water, gas and oil, also can produce construction pipe.
