Majid Mozan Ghtami Group


Our company established a quality management system with the ISO9001: 2008 standard, from the procurement of raw materials to the entire production process, testing the cost of goods, shipped and after-sales service, and has developed a corresponding control procedures to make the whole process of production In the monitoring. Quality inspection personnel and welding workers have been assessed by specialized agencies, special types of employment rate of 100%, so that the quality of products has been guaranteed.

Our company has four production line of Submerged Arc Welding Longitudinal, with an annual output of 750000 tons per year. Our company introduced a high technological equipment automatic welding equipment. And our Submerged Arc Welding Longitudinal steel pipes are widely used for oil, natural gas industry, heat pipelines, wall casing, construction piling, high-rise building frame structure and water supply.


How Do We Work ?

Longitudinal Submerged Arc Welding (LSAW) Processes Longitudinal Submerged Arc Welding is a specific welding technique used in pipe production where the finished product requires a particularly high wall thickness due to high internal or external pressures. With this in mind the main applications of LSAW pipes include oil, natural gas, gas, central heating, water supply, sewage treatment and other similar uses. Steel pipes are long, hollow tubes that are used mainly to convey products from one location to another. They are produced mainly by two distinct manufacturing methods which result in either a welded pipe or seamless pipe. In both the manufacturing methods, raw steel is first cast into a more workable starting form (slabs, hot billet or flat strip). It is then made into a pipe by stretching the hot steel slab/billet out into a seamless pipe or forcing the edges of flat steel strip together and sealing them with a weld. 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). Good performances on high pressure resistance, and low-temperature corrosion resistance. 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 specification scope is wide, and have good toughness, ductility, uniformity, compactness, etc. Longitudinal submerged arc welded (LSAW) pipes manufacture process is bending and welding wide steel plates to pipes from leveled hot rolled coils by both the JCOE and UOE (the forming process in which the plate like the letter “J”, “C”, “O” or “U” shape, then expansion) forming processes. In Figure 1 is shown a UOE method for production of longitudinally welded large diameter pipes. Longitudinally edges of steel plates are first beveled using carbide milling equipment. Beveled plates are then formed into a U shape using a U-press subsequently into an O shape using an O-press.

Quality Control

Our company has established a complete joint quality control system of ISO9001:2008/API Q1/pressure pipeline compents production, implements institutionalized management,programmed operation,and achieved nine 100% qualified controlling rate, which are:100% ultrasonic flaw detection for the material plate;100% automatic on-line UT test after welding; 100% whole-length seam X-ray test; 100% inside weld line industrial TV test; 100% hydrostatic test; 100% automatic on-line seam UT test after hydrostatic test, expanding; 100% X-ray test and make X-ray film or picture record on pipe ends; 100% pipe appearance and plate appearance inspection, and all above tests are proceeded by quality control department.The purpose is to ensure our product to meet standard requirement and satisfy the users.
