Kencotube is pioneer stockiest and manufacturer of Long Weld Neck Flanges, which can be differentiated from all other types of flange by their long tapered hub. In Stainless Steel Long Weld Neck Flanges, there is also a gentle transition of thickness in the region of the butt weld that joins them to pipe or a fitting. Carbon Steel Long Weld Neck Flanges is an external or internal ridge, or rim (lip), for strength, as the flange of an iron beam such as an I-beam or a T-beam. Alloy Steel Long Weld Neck Flanges are wheels with a flange on one side to keep the wheels from running off the rails. Alloy 20 Long Weld Neck Flanges is also used for a kind of tool used to form flanges, where pipes with flanges can be assembled and disassembled easily.
Duplex Steel Long Weld Neck Flanges are best suited for severe service conditions, whether loading conditions are substantially constant or fluctuate between wide limits. Super Duplex Steel Long Weld Neck Flanges is suitable for use in hostile environments that have extremes of temperature, pressure or other sources of stress. Meanwhile, the resilience of Monel Long Weld Neck Flanges is achieved by sharing the environmental stress with the pipe with which it is welded. Nickel Alloy Long Weld Neck Flanges with the wall thickness of the flange having the same dimensions of the matching pipe We also offer these flanges at best rates in customized sizes and shapes.
