16mn spiral steel specifications of the material
16mn spiral steel pipe material is 16mn, 16Mn called low-alloy high-strength structural steel: carbon content of 0.1% -0.25%, adding the main alloying elements manganese (Mn), silicon (Si), vanadium (V), niobium (Nb) and Titanium (Ti) and the like.
16Mn is the old country brand name, and now classified as a low-alloy high-strength structural steel, now known as the Q345 grades.
Production Process of 16mn Spiral Steel
Inspection of raw materials - Uncoiling - First flat - Cut to butt welding - Finishing - Milling - Delivery - Molding inside and outside welding - Welding slag clearance External inspection - Automatic repair welding, X-ray inspection, filming and Manual ultrasonic re-inspection - pipe end groove machining - hydrostatic pressure test - automatic length measurement weighing - spray signs - the final inspection - storage
16mn spiral steel pipe implementation standards
SY / T5037-2008 (Ministry superscript, also known as ordinary fluid pipeline with spiral submerged arc welded pipe)
GB / T9711.1-2008 (GB, also known as the oil and gas industry delivery of steel pipe delivery technical conditions Part I: A grade steel pipe (strict requirements are GB / T9711.2 B grade steel pipe)), API-5L (American Petroleum Institute , Also known as pipeline steel pipe; which is divided into PSL1 and PSL2 two levels), SY / T5040-2008 (spiral welded steel pipe pile)
16mn spiral steel pipe use
For liquid delivery with: water supply, drainage. For gas transportation with: gas, steam, liquefied petroleum gas. For structural use: for piling, as a bridge; terminals, roads, buildings and other structures.
