  These feelings with each other in flange production work, especially easy to output to the spark of innovation thinking, give a person on spiritual incentive. Second, heating specification and forging temperature range, the furnace heating surface carburizing easily, so first to avoid contact with any carbon material, and used the oxidation of heating medium, thereby reducing steel carburizing phenomenon, prevent intergranular corrosion. Because some caliber has a few meters large, weld a need a relatively long time, need fire makes sweet malt.

  butt welding steel flange and pipe flange is used for welding, mainly use in welding technology, the use of good characteristics and performance, 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 for.. The butt welding of flange with concave and convex type sealing surface. Large blind flange is a solid circle, with handle for conditions usually held in a state of isolation system. Shall not adopt steel plate machining directly into with butt welding neck flange; Butt weld ring should be heat treatment after welding, and 100% ray and ultrasonic flaw detection, and radiographic conform to the requirements of the JB4730 of class II, ultrasonic testing conform to JB4730 class I requirements.

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