Loose Flanges Manufacturer

Loose Flanges Manufacturer

To fit elbows, valves, or almost every form of pipeline component currently in use, there are loose flange types. To make one side of a flanged coupling, a device called a loose flange is welded onto the end of a piece of pipe. The component can be built of carbon steel or stainless steel depending on the desired application. It consists of a flat steel forging with bolt holes all the way around and an opening in the middle that is the right size for the pipe that will be welded onto a loose flange.

We are a reputable company offering a wide selection of high-quality Monel Loose Flanges that are guaranteed to have great reliability, stability, strength, and enduring characteristics and are in high demand in the Indian market. We specialise in the supplying and trading of a wide range of top grade Hastelloy Loose Flanges that have undergone testing and verification for strength, accuracy, and precise building requirements. Our exported and supplied titanium alloy loose flanges are renowned in the industry for their strength and exact design features. Numerous mechanical, engineering, and structural industries use nickel alloy loose flanges.

We at JK Engineering Works would like to take the opportunity to introduce as a leading Industrial Carbon Steel Loose Flanges Exporter in India. Stainless Steel Loose Flanges are stocked or available in the following range of materials and sizes for the oil, gas, petrochemical and allied industries. Pipes with Loose Flanges can be assembled and disassembled easily. Loose Flanges can be forged or plate.
