Event Details

  • Steel shot and steel grit mixed abrasive, usually the hardness of steel shot to 4050 HRC harder to 5060 HRC can be used in all kinds of steel surface, even in the class C and D corrosion of steel surface, cleaning effect is very good also.It stands for material Q235A and b-grade steel.).The material is 0Cr13, 0Cr19Ni9, 00Cr19Ni11, 00Cr17, 0Cr18Ni11Nb, 0017Cr17Ni14Mo2, etc.It is mainly used for low pressure fluids such as water, sewage, gas, air and heating steam etc.GB/T14980-1994 (low pressure fluid transmission with large diameter welding steel pipe).The raw material used in the straight seam is steel plate or strip steel, which is divided into furnace welding tube, electric welding (astm a53 erw steel pipe ) tube and automatic arc welding tube because of different welding process.It is mainly used for low pressure corrosive medium.Usually in order to achieve the ideal cleaning effect, should according to the appearance of hardness, straight seam welded pipe equipment requirement of original corrosion level, surface roughness, coating types to choose abrasive, such as for single layer, layer or three layer PE coating epoxy, using a mixture of steel shot and steel grit grinding are more likely to achieve ideal cleaning effect.The common material of the welded steel tube is: Q235A, Q235CQ235B, 16Mn, 20 Hardware Accessories, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 1cr18ni11, 0Cr18Ni11Nb, etc.GB/T12771-1991 (fluid conveying stainless steel # welded steel pipe)..Its representative material is: Q235A class steel.Steel pellets have the effect of reinforcing steel surface, while steel sand has the effect of etching steel surface.It is divided into round welded tube and heterotype (square, flat, etc.It is mainly used in mine pressure, drainage, axial gas and steel pipe.It stands for material 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, etc.Straight seam welding steel pipe is divided into several types because of its materials and USES:GB/t3091-2001 (low pressure fluid conveying galvanized steel pipe).It is mainly used for conveying water, gas, air, oil and hot water or steam.Mainly used in mechanical, automobile, bicycle, furniture, hotel and hotel decoration and other mechanical parts and structures.GB/t14291-2006 (mine fluid conveyer welded steel pipe).GB/t12770-2002 (mechanical structure stainless steel welded steel pipe).It stands for material Q235A steel.Otherwise, decorative welded stainless steel pipe (GB/T 18705-2002), building decorative stainless steel welded pipe (JG/T 3030-1995), low pressure fluid conveying with large diameter welded steel pipe (GB/T 3091-2001), and the heat exchanger with welded steel pipe (YB4103-2000).
