We manufacture all type of flanges confirming to b. S. 10 standard table d, e, f, h, ansi b 16.5 class 150, 300, is 1538 12″ to 20″, plate thickness 6 mm to 40 mm. We have wide range of forged & machined flanges made from carbon steel material confirming to astm, din, jis, gost, etc. 1. Slip –on or hubbed flanges. This type of flange, as implied by its name, has a diameter slightly larger than the pipe so that it can slide over the pipe to fit snugly. Though they are thinner than most other flanges, they are strong, dependable, and cost-effective. 2. Threaded flanges . Similar to the slip-on, this flange slides over the pipe but is popular because it can be attached without welding since it is designed with tapered threads to work with pipes that have external threads. Also low cost, it’s great for small pipes and highly combustible areas where welding is dangerous. 3. Lap joint or loose flange. Used in conjunction with a universal stub end fittings, this flange is often used to avoid issues that could arise with the alignment of bolt holes. Stub end fittings are welded to the pipe, and the lap joint flange is designed to slide over the pipe and rotate around the stub end. They are commonly used in applications where the juncture does not come in contact with the fluid or gas making them reusable, and they are also beneficial in applications keeping down expenses when exotic metals are used. 4. Welding neck flanges… often used for high-pressure applications to reduce the concentration of stress, this type of flange has a neck that is welded to the base of pipes. One of the most popular options for high-pressure systems, the tapered hub offers strength and flexibility.
