Neck Steel Pipe Flange

NeckSteel Pipe Flange

Neck steel pipe flange isa pipe fitting which has a neck and is welded to the pipe. Neck steel pipeflange has a strong rigidity and it is not easy to deform and performs a goodsealing task. Its price is low and its nominal pressure is less than 2.5 MPa. The neck steel pipe flange is widely used in largepressure and temperature variation pipelines as well as high or low temperatureand high pressure pipelines. Besides, neck flange with nominal pressure PN16MPais also used in pipelines transporting expensive, inflammable and explosivematerials.

The neck steel pipe flange is widely used in electricity, oil and gas,petrochemical, chemistry, ship building, heat supply, paper making,metallurgical and other industries. Neck steel pipe flange is mold forged first and thenmachine finished. The neck flange out diameter ranges from 3/8"to 160" and its nominal diameter ranges from DN10 to DN4000. It hasbeautiful shape with smooth surface. It is acid and alkali resistance withanticorrosion as well.

Our company provides neck steel pipe flanges to work under pressure inaccordance with American standards such as CLASS 150, CLASS300, CLASS 400, CLASS 600, CLASS 900, CLASS 1500 and European standards such as PN6, PN 10, PN 16, PN 25, PN 40, PN 63 and PN 100. What’s more, our companyoffers different flange facing types in accordance with American standards likefull face, raised face, tongue, groove, female, male and ring joint. To theEuropean standards we offer full face, raised face, tongue, groove, female, male and ring joint.
