DIN Flanges | DIN 2527-2638 | PN6-PN100
DIN flanges are standardized pipe flanges used across European and international piping to make strong, leak-resistant connections between pipes, valves, pumps, and other equipment. Built to DIN and related EN standards, they come in several designs, including welding neck, slip-on, blind, loose, and threaded flanges, which covers a wide spread of industrial work. You will find them in water treatment plants, chemical processing units, oil and gas systems, power stations, food and beverage facilities, and general mechanical piping, anywhere dimensional consistency and a dependable seal matter. PM Industries manufactures, supplies, and stocks DIN flanges in a full range of types, sizes, and PN ratings.
The standardized drilling pattern is a big part of the appeal. With accurate dimensions across the board, DIN flanges interchange easily, simplify maintenance, and go in without fuss. They are made in PN pressure classes such as PN6, PN10, PN16, PN25, PN40, and higher, so engineers can match the flange to the working pressure of the line. We produce them in carbon steel, stainless steel, alloy steel, and other special grades, picked to suit the corrosion resistance, temperature, and service the job demands. The design supports solid gasket seating and strong bolting, which keeps leaks down and lifts system safety over the long run.
DIN flanges also earn their place through flexibility. The right standard and material grade lets them serve both low-pressure and high-pressure systems. Getting the flange type, face finish, pressure rating, and material right is what keeps the flange compatible with the piping and delivers long service life, and our team will help you confirm those before you order.
For industrial piping that needs accuracy, strength, and standardized performance, DIN flanges are a dependable, widely accepted choice. PM Industries holds stock ready to ship, with certification and test documentation on every order. Tell us your flange type, size, PN class, face, and material, and we will quote it.
