A Long weld neck flange (LWN flange) which is also called Integral Flange, is used for high pressure situations, Long weld neck flanges are used and for very high pressure cases Long Welding Neck flanges are preferred. In this case, the weld are far from the ring to avoid bending stresses and weld stress being combined.
When we set up our stockholding division ‘Stock Services’ in 2008 we begun with the goal of becoming one of the top three distributors of stainless steel SEAMLESS fittings, buttweld pipe fittings, forged pipe fittings & pipe flanges in India. In 2010 we’ve got our own manufacturing plant in India and Ras Al Khaimah & since then we have developed our range further to include Long Weld Neck Flanges, ANSI B16.5 Long Weld Neck Flanges, ASME B.16.5 Long Weld Neck Pipe Flanges, DIN Long Weld Neck Flanges. Our range of seamless pipe fittings and pipe flanges are held in dual certified grades 304/304L and 316/316L, and you can find accurate & best price here on our website.
We can now provide fittings and flanges in one package, and with our experience in distribution, can ship Stainless Steel Long Weld Neck Flanges, ASTM B.16.5 Long Weld Neck Flanges, Carbon Steel Long Weld Neck Flanges all over the world on quick lead times.
Below are our available Long Weld Neck Flanges that will meet your project needs. We will help you put together your entire project and ship it to your closest port. We ship globally!
