UNI Flange

Check online Dimensions of Series 2282/ 1400/ 1300 UNI Flanges

A flange is an efficient device used to connect pipes, tubes, valves, and other equipment to create a versatile pipeline. A UNI Flange provides an economical method for making correct connections directly on the site. These flanges eliminate the problem faced due to pre-engineered or fabricated pipes. The uni flange 1400 allows deflection of the pipe during installation. This allows it to make a connection when other flange types fail. The flange has in-build anchoring and tie rods to hold them in place. A uni flange 1300 covers standard specifications for pressure and temperature rating of flange sizes of NPS ½ to NPS 24. These flanges have a smooth, stock, and concentric serrated finish. The flange uni 2282 can be threaded or welded in place. These flanges can have a ring-type joint, flat face, and raised face contact face. A UNI 2282 flange can work in temperatures up to 400 degrees F and can be availed in class 150 to class 2500. These flanges are produced following all international and national standards.

The UNI 1400 Lap Joint Flange is designed with a two-component assembly consisting of a stub end with a lap-joint ring flange as it is placed over it. These rings can be easily rotated to align them to the mating flange. The flange connection is well suited for large or hard-to-adjust flange types. Our company is a UNI Flange manufacturer who produces all our items with the best raw materials and cutting-edge technology to produce class apart products.

We keep ready stock of UNI 2223 flange and UNI Flange 1300 in Mumbai
