Production Standards of LSAW Pipe
UOE LSAW Pipe
The term UOE is the abbreviation for U-O-E, which is a method used for the production of longitudinally welded large diameter pipes. The production process of UOE pipes is divided into three steps: pre-bending, forming, and longitudinal welding.
- First, the plate is pre-bent by different radii by a variety of forming presses.
- After that, it will be deformed into U-shape and O-shape by a specific forming press.
- Finally, these two pre-shaped plates are welded together in an LSAW process to form a final tube with satisfactory wall thicknesses.
The specific UOE production process
steel plate feeding → welding arc plate → milling → pre-bending → U forming →O forming → high pressure water washing → drying → Pre-welding → internal welding → external welding → Removal of arc guide plate → ultrasonic inspection of weld and tube end → X-ray inspection → expansion of steel pipe → smoothing of tube end weldPipe end flat head → water pressure test → ultrasonic inspection of weld and pipe end → X-ray inspection of weld and pipe end → chamfering →Pipe end delamination and magnetic particle detection → remanent demagnetization → factory inspection → Weighing, measuring length → spray marking →Upper protection ring → Stacking and delivery.
JCOE LSAW Pipe
The JCOE pipe is a kind of special pipe that is manufactured by connecting two pipes into a J shape, bending them into a C shape, bending them into an O-shape, and then arc welding the abutting edges together.
The JCOE pipe has the same function as ordinary pipes but with improved quality, better processability, and more convenient transportation.
This creates an interior-facing square or rectangular channel for the wrapped forming core material and an exterior-facing curved surface.
The body is expanded by high-pressure air cylinders to control dimensions.
The specific JCOE production process
Material reinspection → vacuum lifting → board probing → turning → edge planing → Top plate → crimping the first half of the steel plate (J forming)→Release → Input back half sheet → crimped back half sheet (C forming)→ Release → Back bending → pre-welding →Lead (quench) arc plate → internal welding → root cleaning → external welding → lead (quench) arc plate → ultrasonic inspection → mechanical expanding →Hydraulic test → mechanical end repair → Ultrasonic test → UT layer test → X-ray test →Finished product inspection → magnetic particle inspection → Weighing and measuring → external anti-corrosion → internal anti-corrosion → marking → delivery.
Difference between LSAW pipe and SSAW pipe
LSAW and SSAW are SAW (submerged arc welded) pipe variations. SAW pipes are mostly used for transporting oil and gas.
The distinction between them is the technique in which they are welded.
- In LSAW pipes, the welding is longitudinal, meaning that steel (hot-rolled coil plate) is rolled into a pipe and the seam is longitudinally welded.
- In SSAW, steel coils are spirally welded, like a helix, such that the coil (strip) adopts the shape of a pipe.
