Product Description
A weld neck flange features a long, tapered hub that smoothly connects to the pipe or fitting via butt welding. During installation, the pipe end is inserted into the flange and welded around its circumference, forming a strong, leak-proof joint. The hub's design reinforces the flange, reducing the likelihood of distortion or damage.
Widely used in high-pressure and high-temperature applications across industries such as petrochemical, oil and gas, and power generation, weld neck flanges are produced from materials like carbon steel, stainless steel, and alloy steel to meet diverse operational demands.
