Product Description Product DescriptionFlat welding flange is a flange connected with container or pipeline by fillet weld. It is an arbitrary type flange.1. According to the degree of integrity of the connection between the flange ring and the straight cylinder section, the flange is checked separately according to the integral type or loose type.2. Flange rings are available with neck and without neck. Compared with the welding neck flange, the flat welding flange has simple structure and saves materials, but its stiffness and sealing are not as good as the neck welding flange.3. Flat welded flange is widely used in the connection of medium and low pressure vessels and pipelinesKey Features:1. The flat welding flange not only saves space and reduces weight, but also ensures that the joint will not leak and has good sealing performance.2. The compact flange size is reduced because the diameter of the seal is reduced, which will reduce the cross section of the sealing surface.3. The flange gasket has been replaced by a sealing ring to ensure that the sealing face matches the sealing face. In this way, only a small amount of pressure is needed to compress the cover tightly. With the reduction of the required pressure, the size and number of bolts can be reduced accordingly, so the final design of a small size and light weight (compared with the traditional flange weight reduction of 70% ~ 80%) of the new product.Standard Specification:Dimensions : ANSI B16.5, ANSI B16.47 Series A & B, MSS SP44, ASA, API-605, AWWA, Custom DrawingsSize: 1/2" (15 NB) to 48" (1200NB)Class: 150 LBS, 300 LBS, 600 LBS, 900 LBS, 1500 LBS, 2500 LBS, DIN Standard ND-6,10, 16, 25, 40 Etc.BS: BS4504 , BS4504, BS1560, BS10Flange Face Type: Flate Face (FF), Raised Face (RF), Ring Type Joint (RTJ)Material: Stainless Steel, Carbon Steel, Low-Temperature Carbon Steel, Alloy Steel, ECT.Surface treatment: Anti-rust oil, transparent/yellow/black, Anti-rust paint, Zinc, Hot dipped galvanizedUsage: Oil field, Offshore, Water system, Shipbuilding, Natural gas, Electric power, Pipe projects, etc. PipeFlange theoretical weight (kg)Single head bolt configurationConfiguration of nutNominal diameterOuter diameterPipe pressure0.6MPa1.0MPa1.6MPa2.5MPaHexagon nut (crude) GB41-76Hexagon nut GB52-760.6MPa1.0MPa1.6MPa2.5MPaQty * Dia * LWeight (kg)Qty * Dia * LWeight (kg)Qty * Dia * LWeight (kg)Qty * Dia * LWeight (kg)Qty * Dia * LWeight (kg)Qty * Dia * LWeight (kg)10140.3130.4580.5470.6344*10*400.140084*12*400.197164*12*500.232684*12*500.232681000*6*52.321000*1.6*50.07515180.3350.5110.7110.8044*10*400.140084*12*400.197164*12*500.232684*12*500.232681000*8*55.671000*2*50.11920250.5360.7480.8670.9854*10*500.164724*12*500.232684*12*500.232684*12*600.26821000*10*510.991000*2.5*50.2225320.6410.891.1741.1744*10*500.164724*12*500.232684*12*600.26824*12*600.26821000*12*516.321000*3*50.39332381.0971.41.61.964*10*500.164724*16*600.48844*16*600.48844*16*600.48841000*14*525.281000*4*50.84440451.2191.7122.64*10*500.164724*16*600.48844*16*600.48844*16*700.55161000*16*534.121000*5*51.2450571.3482.092.612.714*10*500.164724*16*600.48844*16*700.55164*16*700.55161000*18*544.191000*6*52.31765731.672.843.453.224*10*500.164724*16*600.48844*16*700.55168*16*701.10321000*20*561.911000*8*55.67480892.483.243.714.064*10*600.189364*16*600.48848*16*701.10328*16*801.22961000*22*575.941000*10*510.991001082.894.014.864*16*600.48848*16*701.10328*16*801.22968*20*802.03681000*24*5111.91000*12*516.321251333.945.46.478.264*16*600.48848*16*701.10328*16*801.22968*22*902.71521000*27*51681000*14*525.281501594.476.127.9210.48*16*600.97688*20*802.03688*20*802.03688*22*902.71521000*30*5234.21000*16*534.121751945.547.448.8111.98*16*701.10328*20*802.03688*20*802.036812*22*1004.43041000*36*5370.91000*18*544.192002196.078.2410.114.58*16*701.10328*20*802.036812*20*903.350412*22*1004.43041000*42*5598.61000*20*561.912252456.69.311.7178*16*701.10328*20*802.036812*20*903.350412*27*1007.31161000*48*5957.31000*22*575.942502738.0310.715.719.912*16*701.654812*20*803.055212*22*904.072812*27*1007.31161000*56*514201000*24*5111.930032510.312.918.126.812*20*803.055212*20*803.055212*22*904.072816*27*11010.46881000*64*519121000*27*516835037712.5915.923.334.3512*20*803.055216*22*905.430416*22*1005.907216*30*12014.00481000*72*525841000*30*5234.240042615.221.83144.916*20*804.073616*22*905.430416*27*11010.468816*30*13014.89281000*80*533931000*36*5370.945047817.5924.440.251.9216*20*804.073620*22*906.78820*27*12013.98620*30*13018.6161000*90*548721000*42*5598.650052920.6727.755.167.316*20*904.467220*22*906.78820*30*13018.61620*36*15031.321000*100*567321000*48*5957.360063026.5739.480.3-20*20*905.58420*27*11013.08620*36*14029.72-The manufacturing process of forged flanges begins with the selection of high-quality steel, which is heated and shaped under high pressure in forging dies to enhance its strength and durability. After forging, the flanges are trimmed, heat-treated to relieve internal stresses, and precisely machined to meet the required dimensions. They undergo rigorous inspection and testing for quality assurance, followed by surface treatments for enhanced corrosion resistance. This process results in flanges that are strong, reliable, and suitable for demanding industrial environments.Company ProfileDingxiang Country Gu Cheng Forging Company Ltd. is a leading manufacturer in Dingxiang County, Shanxi Province, known as the "Forging Capital of China."
