stainless Steel Flanges

Om Tubes and Fittings is manufacturers & suppliers of Stainless Steel FlangesOm Tubes and Fittings Industries is one of the leading and foremost brands in the Steel industry. We are the best suppliers of steel products over a past decade and our product delivery is the fastest in the world. We are the most experienced and proficient makers of the nickel-based alloy. Om tubes mainly specialize in the various nickel, stainless, duplex and super alloys in the form of the plate, sheet, bar, tubing, pipe, flanges, fittings, wire and welding material. We serve customers in various countries with all size demands. We supply, process and custom fabricate product for various industries including chemical processing, mining, oil and gas, power generation, petrochemical and more. Great emphasis is paid to value added and after sales services. The main goal of this organization is to provide commodities of unparalleled quality, in addition to making our client’s buying experience world-class and a memorable one.Today, our industry is filled with high volume but low-quality suppliers which are below the mark of what the steel industry needs. Because of such circumstances, it results in the decline of the quality of goods and hence, the entire project. But today, our firm is one of the proficient organizations in the steel industry.All our hard work and commitment are directed towards our clients resulting in an excellent purchase cycle. That makes us unique from the rest. We boast of having distributing our products in more than 13 countries in the world, especially to several European, African and Gulf-based companies, for over a decade. Consequently, our clients give our company as a recommendation to other prospectors which itself is enough to prove our transcendence in the steel industry.


Stainless Steel Flanges are connection supports which look like a plate or a ring with holes for connecting bolts used in a pipeline to connect two major pipelines. The mechanical support provided by flanges provides a steady equipment design for the pipeline. For supporting a greater mass, a heavier flange body is required. The structural strength provided by the Stainless Steel Flanges is a great value addition required in the pipeline design. These flanges are connected to each other with the use of fasteners and gaskets. Stainless Steel Flanges are usually welded or screwed. Joints are formed by bolting together two flanges between them to provide a seal. The term “flange” is also used for a kind of tool used to form Stainless Steel Flanges. Pipes with these flanges can be assembled and disassembled easily.


Stainless Steel Flanges can be declassified into various types:

All the above Stainless Steel flanges can be made in raised face with the hub or without the hub.

Stainless Steel basically is an alloy of Iron with a minimum 10.5% of Chromium in it. The Chromium produces a thin layer of oxide on the surface of the steel known as the ‘passive steel’ and hence the “Stainless” appearance. Increasing the amount of Chromium increases the resistance against the corrosion of the steel. Along with Chromium, Stainless Steel also contains varying amounts of Carbon, Silicon and Manganese. Other elements such as Nickel and Molybdenum may be added to impart other useful properties such as enhanced sturdiness and increased corrosion resistance. As an element, Stainless steel is 100% recyclable, corrosion resistant, conserving-free, tenacious and hygienic.

The stainless steel family tree has several branches, which may be differentiated in a variety of ways e.g. in terms of their areas of application, by the alloying elements used in their production, or, perhaps the most accurate way, by the metallurgical phases present in their microscopic structures –

Martensitic (including precipitation hardening steels)
Duplex steels, consisting of mixture of ferrite and austenite.

Austenitic : Austenitic steels have austenite as their primary phase (face centered cubic crystal). These are alloys containing chromium and nickel (sometimes manganese and nitrogen), structured around the Type 302 composition of iron, 18% chromium, and 8% nickel. Austenitic steels are not hardenable by heat treatment. The most familiar stainless steel is probably Type 304, sometimes called T304 or simply 304. Type 304 surgical stainless steel is an austenitic steel containing 18-20% chromium and 8-10% nickel.

• Good to excellent corrosion resistance
• Good weldability and formability
• Good creep resistance
• Non-magnetic

Austenitic types have good to excellent type of corrosion resistance, and has exceptional molding ability and durability.

Ferritic : Ferritic steels have ferrite (body centered cubic crystal) as their main phase. These steels contain iron and chromium, based on the Type 430 composition of 17% chromium. Ferritic steel is less ductile than austenitic steel and is not hardenable by heat treatment. Molybdenum may be combined to some grades to improve corrosion resistance. These type of steels are magnetic because of their ferritic structure.

• Low Carbon and Nickel content
• Good Weldability and Toughness
• Magnetic

Martensitic : The characteristic orthorhombic martensite microstructure was first observed by German microscopist Adolf Martens around 1890. Martensitic steels are low carbon steels built around the Type 410 composition of iron, 12% chromium, and 0.12% carbon. They may be tempered and hardened. Martensite gives steel great hardness, but it also reduces its toughness and makes it brittle, so few steels are fully hardened. These grades contain no, or small, amounts of nickel, and molybdenum is seldom added. Adding some nickel and reducing the carbon content improves the poor weldability of martensitic grades.

• High Strength
• Formidable Wear-Resistance
• Low Corrosion Resistance.

Typical Applications of Stainless Steel Flanges include:

• Oil and gas industries.
• Research and development.
• Hydraulics – One of the topics in applied science and engineering that deals with the mechanical properties of fluids.
• Pneumatics – The branch of physics and technology that deals with the mechanical properties of the gases.
• Plumbing, pharmaceuticals, food and sanitary departments.

We offer our products at customer-friendly prices. Although the prices of the Stainless Steel Flanges will vary according to the particular element used for making the Stainless Steel Flanges  and also depending upon its specifications and its effective properties.
