Weld Neck Flange and Stainless/ Carbon Steel WNRF Flanges manufacturer

ANSI/ ASME B16.5 Stainless Steel Weld Neck Flange manufacturer And supplier In Mumbai, India

Flanges available in the market are in different forms, shapes, and sizes. One such type is the Weld Neck Flange that is recognized by its long tapered hub that goes towards the wall thickness. Due to the welded neck of the WN Flange, they are used in applications with high pressure, high temperature, along with the ones that work in sub zero temperature. The transition of the WNRF Flange from flange thickness to pipe is said to be beneficial under conditions of bending that are caused by line expansion.to avoid restriction of product flow ASME B16.5 Long Weld Neck Flange are bored to match the inside diameter. This prevents erosion of LWNRF Flange as well as prevents turbulence at joints.

Reducing Weld Neck Flanges provide good sealing and are not easy to deform. JIS 16k Long Weld Neck Flange has a corresponding rigid and elastic demand along with good butt thinning transition. These Raised Face Weld Neck Flange are used in a wide range of applications and are said to be suitable for temperature and pressure fluctuations of pipe. Carbon Steel Weld Neck Flange used in low temperature pipes has a PN greater than 2.5 MPa valve connections. 6 Inch Weld Neck Flange is also used for transferring flammable, expensive, and explosive media. However these 3 Inch Long Weld Neck Flange also have certain disadvantages such as they are expensive and heavy in weight.

According to Stainless Steel Weld Neck Flange Manufacturer In India, these flanges are large and are difficult to install. WNRF Class 150 Flanges distribute stress through the tapered hub. Aluminum Weld Neck Flange can be easily radiographed for flaw detection. Weld Neck Pipe Flange provides a superior and natural form of connection between the pipes. Table E Weld Neck Flange are beveled and are inspected post-weld to ensure that the seal is uniform and does not look abnormal. As per Dimensions Weld Neck & Blind Flanges, ASME B16.47 Series A Class 300 the blind flange has greater thickness and weight when compared to the weld neck. We have been producing supplying various flanges including Welding Neck Flange Type 11 at affordable prices to our customers for decades now.

Long Weld Neck Flange Weight Calculator

ASME/ ANSI B16.5 Class 150 LWNR flange can be calculated by using the following equation:

Mass = [ ( X + B ) / 2 * ( X – B ) / 2 * 0.0246615 * ( Y – T ) * 10-3 ] + [ ( D2 – B2 – nd2 ) * T + ( G2 – B2 ) * t ] * 6.165375 * 10-6, Assume that the flange is made of carbon steel.

LWN Flange Vacuum Range

Elastomer seal: >=1 x 10^-8 Torr – High vacuum
EVAC metal seal: >=1 x 10^-11 Torr – UHV

Long Weld Neck Flange Temperature Range

Viton: -20°C to 200° celsius
Silicone: -50°C to 230° celsius
Buna: -30°C to 110° celsius
EVAC metal seal: -270°C to 150° celsius
