Long Neck Butt Weld Flange
I. product introduction
Long neck butt welding flange is not easy to deformation, sealed, widely used, suitable for pressure or temperature fluctuations of the pipeline or high temperature, high pressure and low temperature pipeline, the advantage is the price is relatively cheap, nominal pressure not more than 2.5MPa; Also used for conveying expensive, flammable, explosive medium pipeline, nominal pressure in PN16MPa or so.
Ii. Product parameters
Specification: DN500 pn 1.0m (convex)
Dimensions: od 640* id 500* thickness 44*
Height 106 24 holes 23 material:
Iii. Product advantages
Pressure vessel long neck butt welding flange JB/T4703-2000 is suitable for the pressure of 0.25-1.6 mpa, the working temperature is higher than 20 ~ 300 ° c steel pressure vessel, the connection is not easy to deformation, good sealing effect, wide application, apply to the temperature or pressure fluctuate dramatically pipe or high temperature, high pressure and low temperature pipes, also used for conveying expensive medium, flammable and explosive medium, toxic gas pipeline. Company can according to the international and domestic various standard (American standard series >. > Germany standard series. Series British standard >, Japan series standards >, the Italian standard, countries such as Australia and China standard standard) the production of various materials (carbon steel, alloy steel/high, low temperature steel, stainless steel/containing dual phase steel, etc.) of forging steel flanges, products have been applied in petrochemical industry, power (nuclear power, wind power and thermal power), light industry, machinery, metallurgy and shipbuilding and other fields.
Long neck butt welding flange (LWN) : it is actually an expanded form of butt welding flange with neck. Flange neck slightly straight cylinder type, neck height should be 229mm (≤DN100) or 305mm (> DN100). Flange neck does not process groove, groove processing can refer to the relevant requirements of hg20615-2009 related standards and customer consultation. Long neck flanges are often used in the CLASS series of pipe flanges. When the pipe flanges with nominal size less than or equal to DN50 are matched with the cylinder body, the use of long neck flanges can also avoid the welding difficulties caused by too thin wall thickness of the neck end of the flange.
