Welcome to Henan BBN Steel
Hot Rolled Plates EN10025-4 S275M steel supplier MachiningAfter final forging/forming and Heat treatment process, all the pipe Fittings, Flanges, Fasteners, Etc. are sent for machining i.e. and preparation, O/D and I/D matching as per dimensional codes. An Expert Q.C. engineer is involved and he keeps constant vigil on every machining operation. Step machining is carried out as required by the codes. GO and NO-GO gauges are used to check the O/D & I/D of the fittings, Flanges, etc.
We have 4 typical production lines EN10025-4 S275M steel supplier, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. The Seamless pipe production line range is OD 10.3mm-965.2mm, wall thickness 1.0mm-60mm, Annual capacity is 500 thousand tons. LSAW pipe production line range is OD 406mm-1524mm, wall thickness 6mm-50mm, Annual capacity is 150 thousand tons.
After the official operation of the national pipeline network in October 2020, relevant oil and gas pipeline construction projects have accelerated. The main planned projects include West-East Gas Pipeline 4 and 5, New Gas Pipeline (Xinjiang Coal-to-Gas Export Pipeline Project) and LNG ( Liquefied natural gas) export pipelines, etc.
The blanking of the structural steel plate is first to find 90 degrees, and then use a tape measure and a powder line to draw the cutting range. According to the thickness of the carbon steel plate plus the cutting allowance, drilling is required. For the deep processing of EN10025-4 S275M steel supplier structural steel sections or profiles: First use a square ruler or a curved ruler to find 90 degrees, and then use a square ruler or a ruler to cut the line and add the cutting margin to the hole.
