Stainless Steel Long Weld Neck Flange
Manufacturer of LWNRF Flange in India, At Lowest Price
Long Weld Neck Flange has an extended neck that is welded to the flange. The extended neck guides the pipe into the flange and has additional surface for fitting and grip. This type of flanges provide an added reinforcement to the connection. The Stainless Steel Long Weld Neck Flange is constructed from grades of austenitic stainless steel of 304 and 316. However, there are other materials namely carbon steel, duplex steel and high alloy steels used in construction of the flanges.
The material grade is chosen based on the chemical, mechanical and physical property requirements of the applications. The Carbon Steel Long Weld Neck is used in high wear and tear applications. The carbon steel flanges are also tougher than their stainless steel counterparts. There are different sizes and dimensions to these flanges according to different standard specifications. The Pn16 Long Weld Neck Flange has a pressure number of PN16 while there are flanges that range from Pn6 through PN64. These are also noted by the pressure classes of the pressure classes ranging from class 150 through the class 2500. The Asme B16.5 Long Weld Neck Flange can have an overall siz get determined between the range of ½ inches to 48 inches.
The pressure numbers and pressure classes are dependent on the flange material, the diameter and dimensions of the flanges. The ASME 16.48 Spectacle Long Weld Neck is a special type of flange in which the shape resembles a spectacle. There is a disc and a ring joint together at one point on the exterior so that the disc or the ring could be switched to fit onto the pipe. The usage is that the pipe can be opened and closed as necessary by just rotating the ring or disc into place.

ASME B16.5 Long Weld Neck Flange
Weld Neck Flanges means a circular fitting with a ring on the circumference. These are machined from a forging and these are butt welded to a pipe. This is used in the industries where high pressure is required. Weld neck flanges manufacturers are India can be found in bulk, but the one which is leading and trust-worthy one is regal sales corporation. We use “A” grade quality material and thus the product is manufactured in a perfect way. Weld neck flanges dimensions consists of outer and inner diameter of the body, bolt circle and bolt hole diameter, length of the hub and many other factors are involved.
