Hebei stainless steel pipe industry Chiho eccentric head Material: Stainless steel-diameter pipe (304304l316316l) eccentric reducer, alloy steel, carbon steel size head diameter pipe diameter pipe 20 steel q234q345 and other eccentric reducer is characterized by intensity. significantly higher than the same amount of carbon carbon steel, has good toughness and ductility and good weldability and corrosion resistance. eccentric reducer made of carbon steel, representation is the largest diameter multiplied by the small head diameter stainless steel necking eccentric head forming process is the same diameter as the diameter pipe big end of the tube into the forming die, along the axial direction of the tube pressing the metal along the cavity forming motion and contraction according reducers Reducing the size of the tube, into one or more press-forming press-forming eccentric reducer standard: GB American Standard British standard and non-standard high-pressure press is one of the chemical eccentric reducer eccentric reducer pipe production Manufacturers, for connection of two different diameters. Quality Chiho Hebei Industry 304 concentric reducer should be consistent with existing national standards, "welded steel seamless pipe fittings" GB / T 12459-2005, and should meet the following requirements: 1) size of the first concentric circle of 304 should not exceed 1% of the respective ends of the outer diameter, and the tolerance of ± 3mm eccentric reducer, concentric reducer centerline ends should overlap, their eccentricity tolerance For ± 5mm 2) 304 concentric size head appearance should not have cracks, heavy leather wall thickness greater than the thickness of the large diameter end of the tube section 304 concentric size head inside 12459-2005 standard tolerances DN15-65 caliber: +1.6 - 0.8 inner diameter: ± 0.8 height: ± 2DN80-100 Diameter: ± 1.6 inner diameter: ± 1.6 height: ± 2DN125-200 Diameter: +2.4 -1.6 inner diameter: ± 1.6 height: ± 2DN250-450 Diameter: +4 -3.2 inner diameter: ± 3.2 height: ± 2DN500-800 Diameter: +6.4 -4.8 inner diameter: ± 4.8 height: DN500-600 ± 2 DN650-750 ± 3 DN800 ± 5 wall thickness of not less than 87.5% of nominal wall thickness deviation of positive and negative absolute roundness sum. But generally below 500 roundness within 4MM. Quality 15316L head size should be consistent with existing national standards, size, head size tolerances shall comply with standards. Roundness head size should not exceed 1% of the respective ends of the outer diameter of the eccentric head appearance should not have cracks, heavy leather butt eccentric reducer, thickness should be greater than the thickness of the large diameter end of the pipe section and allow deviation ± 3mm; concentric size head centerline ends should overlap, their eccentricity tolerance of ± 5mm.
