Long Weld neck Flanges
Long Weldnecks Flanges are shaped like a slip on flange with a piece of pipe already attached but are formed and machined in a one-piece construction. They are often used in vessel manufacturing. Long weldnecks are almost identical to weldnecks, but for two differences: they do not h...

MDS Petrochemical manufacture and supply the highest quality of Carbon Steel Flanges to meet the exacting requirements of the International Petrochemical Industry. Our Carbon Steel Flanges are available in various formats such as Slip On, Blind, Weldneck, Socketweld, Threaded, Lap Joi...
Socket Welding Flanges
The Socket Welding Flanges were initially developed for use on small size high pressure piping. When provided with an internal weld, their static strength is equal to, but their fatigue strength 50% greater than double welding slip-on flanges. Smooth bore conditions can readily be att...
Grooved Mechanical Rings
As a leader in engineered oil-field-application products, Pro-Flange supplies a line of approved Grooved Mechanical Rings (GMR). These are used as collars between two pipe ends, over which a gasket and a coupling are installed. We are the only Canadian manufacturer – and the only kn...
Lap-Joint Flanges
