Spiral Steel Pipe rust mainly using tools such as steel wire brush the surface grinding, cleaning and pre-heating coil can be removed loose or tilt of the oxide scale, rust, welding slag. Hand tools rust can reach Sa2 level, power tools rust can be achieved Sa3 level, if the coil attached to a solid surface oxide skin, tools rust effect is not ideal, of the anchor pattern depth of less than anti-corrosion construction requirements.
Standards and classifications
Common standards generally divided into spiral: SY / T5037-2000 (Ministry of standard, also known as general fluid pipes with spiral submerged arc welded pipe), GB / T9711.1-1997 (GB, also known as the oil and gas industries - Steel pipe technical delivery conditions for the first part: a grade steel (demanding a GB / T9711.2 B grade steel)), API-5L (American petroleum Institute, also known as line pipe; which is divided into PSL1 and PSL2 two levels), SY / T5040-92 (pile with spiral submerged arc welded pipe).
