Frequently Asked Questions

What is a stainless steel flange?

A stainless steel flange is a circular component used to connect pipes, valves, pumps, and other equipment in a piping system. It provides a means for easy assembly and disassembly of these components.

How do I choose the right size and class of stainless steel flange for my application?

The size and class of a stainless steel flange depend on factors such as pipe size, pressure rating, temperature, and application requirements. Consult us, at Naysha Steel is recommended for proper selection.

Are there any special considerations when working with stainless steel flanges?

Yes, stainless steel flanges require proper handling to avoid contamination and damage. Welding should be done using appropriate techniques for stainless steel to maintain corrosion resistance.

Industries served by Flanges

In the oil and gas industry, blind Alloy Steel flanges are used in pipelines, storage tanks, and offshore platforms. They are employed for closing off openings during maintenance, repair, or when a branch connection is not required. Petrochemical plants utilize blind Alloy Steel flanges in equipment such as reactors, distillation columns, and storage vessels. These flanges provide a secure and leak-proof seal when closing off unused openings or isolating sections of the process.

Oil and Gas Industries

The oil and gas industry includes a wide range of from drilling and production to refining and marketing. Some of the major players in this include oil and gas companies, service providers, equipment.

Petroleum Industries

In the drilling process, stainless steel is used to make drill bits, pipes, and other equipment that must withstand high pressures and temperatures. Stainless steel is also used to make pumps, valves, and fittings for the transportation.

Shipbuilding in India

In storage applications, stainless steel is used to make tanks and containers that can safely store corrosive and hazardous chemicals. It is also used in piping systems for chemical transfer and distribution chemical industry.

Marking & Pricing

Products are packaged to ensure that there is no damage during of goods transport. In case of exports, standard export packaging is done with utmost care in wooden covering or boxing. All products are marked with Grade, Lot No, Size, Degree and our trade mark. On special requests we can also, make customized marking on our products.

Quality Assurance

At Naysha Steel, all fittings and flanges are subject to strict inspection at each and every stage of the production process, from starting material purchasing to product dispatch. They are visually examined for compliance to ASTM, ASME, MSS, DIN, EN, and JIS codes and standards. Upon request, official certified Inspection Agencies can be called in to witness the material reports, dimensions and quality compliance of products.
