Carbon Steel Welding Neck Flange
Butt welding flange is not easy to deformation, good sealing, wide application, suitable for pressure or temperature fluctuations of pipeline or high temperature, high pressure and low temperature pipes, advantage is that the price is cheaper, nominal pressure no more than 2.5 MPa;Also used to transport is expensive, inflammable, explosive medium pipeline, nominal pressure around PN16MPa.
Scooter in forging, casting, flat welding flange connection Single-sided, double-sided nut connection.Product features Beautiful shape, the surface level off is smooth, acid and alkali resistance, corrosion resistance, simple sense strong performance.Production process and the cutting oxygen furnace, forging press cutting forming or finished product as a whole.High precision CNC lathe turning processing way, nc rocker drill hole.Product parameters: (1) the flange diameter 75 mm to 2190 mm (2) the central circle diameter of bolt holes: 50 mm - 2130 mm (3) the bolt hole diameter: 11 mm to 30 mm (4) the number of bolt hole: 4-48 (5) thread: M10 - M27 flange thickness (6) : 12 mm - 58 mm (7) : pipe diameter (17. 2-2032 - mm) B (14-2020 - mm) flange diameter (8) : A (18-2036 - mm) B (15-2024 - mm) (9) of the flange theory weight: 0.36 kg - 234.6 kg (DN1800)
