Cimolai - production of large diameter and thick pipes Pipes Cimolai is active in the production of large diameter and thick LSAW pipes for Off-Shore structures, Oil & Gas applications, renewable energy and construction. In 2012, Cimolai enters the market for the production and marketing of welded and drawn stainless steel tubes through the acquisition of the Swiss company Zwahlen & Mayr SA. Definition & Means of LSAW pipe Winsteel GroupThis 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 Welding. Outside weld is the tandem multi-wire submerged arc welding on the outer part of the LSAW steel pipe welding. 8. Ultrasonic Testing. This test is checking outside and inside a straight seam
Difference 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). How is the large diameter thick wall pipe welded?In this process, large-diameter thick-walled pipes usually require pressure. There are many energy sources for welding, including gas flame, electric arc, laser, electron beam, friction and ultrasonic waves. Before the end of the 19th century, the only welding process was metal forge welding that blacksmiths had used for hundreds of years.

The same work under pressure, unified diameter spiral welded pipe straight sesm welded pipe wall thickness can be reduced. The pipeline development trend of large-diameter
LSAW Large diameter welded carbon steel pipe Usage:Fluid,boiler,hydraulic,gas,oil,chemical fertilizer,structure pipes etc.For low pressure liquid delivery such as water,gas and oil Alpine zone,the sea,the city densely populated areas. Large Diameter Pipes Dimension Large steel pipe weldingWeld:Adopt multi-wire submerged arc welding on the outside tandem LSAW steel pipe welding. ultrasonic testing:. According to the standard of straight seam welded steel pipe inside and outside the weld metal and the weld heat affected zone on both sides of Longitudinal Submerged Arc Welding (LSAW) Processes In LSAW pipe mills, processing is carried out by cold forming heavy carbon steel plates, the pipe prematerial on which many of the pipe properties depend. The material of LSAW steel pipe is unit middle or heavy thickness sheet, coiled in the molding or forming machine, welded by double submerged arc welding and expand the diameter.
The developing trend of LSAW steel pipe in the future:in terms of the onshore gas,with the large diameter LSAW steel pipe, its single-tube gas transmission capacity could reach the level of 50 billion cubic meters / year, pipe diameter can reach 1422mm, steel grade achieve X80, and gas transmission pressure can reach 12MPa; SSAW Steel Pipe, Spirally Submerged Arc Welded - LandeeWelded Steel Pipe (39) LSAW Pipe (18) SSAW Pipe (7) ERW Pipe (10) Seamless Steel Pipe (112) Cold Drawn Seamless Pipe (13) Hot Rolled Seamless Pipe (16) Hot Expanded Seamless Pipe (6) Precision Seamless Pipe (16) Large Diameter Thick-Walled (6) OCTG Pipe (34) OCTG Tubing (4) OCTG Casing (8) OCTG Drilled Pipe (15) OCTG Sucker Rod (7) Surface dn1400 large diameter lsaw steel pipe, dn1400 large Jul 04, 2020 · 80 dn1400 large diameter lsaw steel pipe products are offered for sale by suppliers on , of which steel pipes accounts for 2%, stainless steel pipes accounts for 1%.
