Chiho Hebei Industry with neck butt flange means with a neck and a tube of transition and connected with the pipe flange welded. Welded flange for pipe or high temperature, high pressure and low temperature fluctuations pipeline pressure or temperature, but also for pipeline transport is expensive, flammable, explosive media. Welded flange distortion, sealed, and widely used, PN at about 16MPa. Butt flange with nominal size is changed, resulting in equal diameter flange often unable to dock, ordering, manufacturing, transportation, installation, repair, maintenance and other practical work is very troublesome, for 0.25,0.6 MPa flange use 1.0 MPa butt size, thickness still use the original three sizes, in order to achieve the docking size of simplicity. Hebei Chiho Pipe flanges production of industrial introduction of production processes forging, casting, scooters manufactured in welded flange connection form sided welding, double-sided nuts. Features beautiful shape, smooth surface with a diameter carbon steel flanges manufacturers, acid, anti-corrosion of carbon steel welded flange with a diameter, strong texture performance. The production process is expected to open sub-oxygen furnace, forged or finished forging cutting overall shape. Precision CNC lathe processing methods, CNC radial drilling holes. With a diameter welded carbon steel flanges, Hebei Chiho (certified), with diameter steel flange provided by Chiho Hebei Industry Co., Ltd. Hebei Chiho Pipe Co., Ltd. (www.hbqh628.com) (www.hbqh628.com) Hebei Cangzhou, forging leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer demand.
