  Butt welding flange related knowledge

  Butt welding flange of technology standards and quality control: feed, physical and chemical, blanking, hot forging forming, heat treatment, inspection, payment processing, inspection, identification, finished goods inspection, identification, packaging type, delivery.

   butt welding flange and pipe flange is mainly used for welding, its structure is reasonable, the strength and stiffness is bigger, can withstand high temperature and high pressure curve and temperature fluctuation, and repeated the sealing is reliable. Nominal pressure of 0.25 ~ 2.5 MPa butt welding flange with concave and convex type sealing surface. Butt welding flange has widely used in pipe fittings and the promotion, need to be carried out in accordance with the corresponding ways and methods to use. Butt welding flange refers to with a neck and a circular tube transition and pipe butt welding flange.

  We have adopted advanced production equipment and technologies to manufacture our blind flanges and socket flanges,which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion.

  Processing method: high precision CNC lathe turning, ordinary lathe car, argon arc welding and other processing

  Nominal pressure: sch5s, sch10s sch20s, sch30s, sch40s, etc

  Manufacturing standards: gb, American standard, the standard, Japanese standard, etc

  Connection mode: flange nut, bolt connection.

  International butt welding flange corrosion resistance, acid and alkali resistant, long service life and so on, the price is reasonable, the surface is smooth, acid and alkali resistant high temperature resistant, reasonable prices, good appearance, texture performance is strong.
