Weld Neck Flanges
WELD NECK FLANGES
The Weld Neck Flanges in India are perfect choice for extreme fluctuations of temperature and environments where there may be excess bending and handling of the flanges. This flange has the buttweld joint.
Because the inside diameter of the flange should match the inside diameter of your pipe, at the time of order it is significant to specify the schedule pipe that is being used for. It has long tapered hub and are frequently used for high pressure applications.
