Al Gharbia Pipe Company Produces First Large-diameter

The new LSAW large-diameter pipe production facility was built at the Khalifa Industrial Zone Abu Dhabi (KIZAD), by a consortium of Larsen & Toubro Limited and SMS group as the EPC (Engineering, Procurement, Construction) partner. The plant is designed for Al Gharbia Pipe Company produces first large- diameter The new LSAW large-diameter pipe production facility was built at the Khalifa Industrial Zone Abu Dhabi (KIZAD), by a consortium of Larsen & Toubro Limited and SMS group as the EPC (Engineering, Procurement, Construction) partner. The plant is designed for a production capacity of 240,000 tons per year. The pipes to be produced on the LSAW Difference between ERW, SSAW, LSAW - Sunny SteelDifference between ERW, SSAW, LSAW. Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).

LSAW Welded Steel Pipe Features and Manufacturing Process6. Inside weld:This is done with a tandem multi-wire submerged arc welding (about four wire) on the inner part of the straight seam welded steel pipe. 7. Outside Weld:Outside weld is the tandem multi-wire submerged arc welding on the outer part of the LSAW steel pipe welding. 8.

Large Diameter Steel Pipe - Things You Must Know before

As we know maximum diameters for ERW pipe usually is 457 mm 16 inch, so we can say the pipe diameters is larger than this OD are known to be large diameters pipes. For LSAW and SSAW large steel pipe:From 508 mm 20 inch to 2540 mm 100 inch. For large diameter seamless pipe also refer to the pipe that more than 16 inch or 20 inch. Large-diameter LSAW Steel Pipe Production Process-HAVTON5. Pre-welding:make a straight seam welded steel pipe after forming and using gas welding seam (MAG) for continuous welding; 6. Inside weld:a tandem multi-wire submerged arc welding (up to four wire) on the inside straight seam welded steel pipe; 7. Outside weld:a tandem multi-wire submerged arc welding on the outside LSAW steel pipe welding; 8. Longitudinal Submerged Arc Welding (LSAW) Processes When operational conditions require high wall thickness due to high internal or external pressures, LSAW (Longitudinal Submerged Arc Welding) pipes are commonly the most economical solution. The LSAW pipe diameter range is larger than ERW (Electric resistance welding), normally from 16 inch (406 mm) to 60 inch (1500 mm).

Hunan Great Steel Pipe Co. newest JCOE production line officially launched its production October 16, 2009. The company spent less than one year and a half commencing from the groundBreaking on April 19, 2008 to the load commissioning on August 31, 2009, which bring a new revolution of JCOE steel pipe in the world. The brief introduction of main equipment - Hebei Allland 4.Inside welding and Outside Welding Equipment The Inside welding and outside welding Equipment of Our LSAW steel pipe is constituted with PLC controlling system ,automatic wire facility, automatic tracing facility, welding gun regulation, soler automatic adding equipment etc.Welding head carry with groove duct which can clear welding seam rubbish,it can prevent rubbish influence for welding The mechanical expansion process of large-diameter steel The steel plate is formed in the order of J type-C type-0 type, and after welding, the diameter is expanded to JCOE welded pipe or non-expanded to JCO welded pipe, Among the above-mentioned LSAW welded pipes, UOE is generally used. The expansion process of large diameter steel pipes is the preliminary rounding stage.
