EIL approved Flanges

Engineers India Limited provides technical regulation for petroleum refineries like pipe fittings, flanges, engineering, technical applications, etc. EIL approved Flanges are highly resistant to extreme temperatures and all forms of corrosion. These flanges are strong and durable and can last for long periods. Apart from this, they offer good mechanical properties not seen in other flanges. They are essential products for oil and gas refineries, chemical, fertilizer, and construction industries. We are the top manufacturers of the EIL approved Flanges in the country from the past decade. We thrive to produce the best products, which are available to all at low rates.

EIL Reducing Flanges

Manufacturer of EIL Approved Slip on flanges in India.

The EIL Approved Slip on flanges is the most preferred and cost-effective flange. These flanges can be easily slid on pipes or valves and welded at the right positions. The EIL Approved Weld Neck flanges can be recognized for their long tapered hub matching the bore of the pipe. This hub provides support to pipes in high-temperature and pressure applications. EIL Forged Flange is prepared by heating a billet and mixing two components of a pipe and then welding them onto piping systems. Our renowned workers make use of the best raw materials using the best technology following international and national standards.

The EIL Reducing Flange is used to join pipes of different sizes and pressures together. These flanges have a shorter neck as compared to other flanges. They are preferred for low-pressure applications. The EIL Approved Expander Flange is an alternative for reducing flange. These flanges increase the pipe size at the flange connection area. Our experienced staff can help customize all our products in different shapes and sizes as per our client’s requirements. If you have any questions about our EIL approved Flanges or other products, contact us to know more.
