The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all there elements to attain a joint, which has acceptable leak tightness.
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term “flange” is also used for a kind of tool used to form flanges.

Seamless pipe is not as strong as Duplex SS 2205 welded pipe, but is very dimensionally accurate. Dimensional accuracy is useful in highly sensitive applications where measurement and calculation accuracy is required.

The A182 Gr. F51 / S31803 material is a typical duplex stainless steel, which contains approximately 50% ferrite and 50% austenite.

The yield strength is also higher, allowing component designers to reduce section size for load-bearing applications.

The yield strength of 2205 is about twice that of austenitic stainless steel. This allows designers to reduce weight and make the alloy more cost-competitive compared to 316L or 317L.

Also known as standard duplex stainless steel, these 2205 duplex bolts are one of the most widely used stainless steel grades.

This is the main reason why Super Duplex Flanges note an improvement of tensile strength over ferritic and austenitic steel grades.

Duplex 2205 stainless steel is resistant to chlorides and H2S. Is a problem solver in most industry segments. Duplex 2205 is utilized in heat exchangers and piping in oil and gas, oil refinery, chemical, and petrochemical industry.

HT PIPE is the government certified and doing business in steel industry for long years and are manufacturing S32750 Duplex buttweld fittings at affordable rates.

ASTM A240 UNS S32750 Plate is a stainless steel alloy with excellent resistance to chloride stress-related corrosion cracking.

We manufacture and supply bar stock for machined, forged and cold formed Duplex 2205 Nuts. We can manufacture and supply Duplex 2205 nuts in imperial sizes from M2 to M150 and 1/4″ to 6″. The most commonly used nuts are heavy hex nuts, flange nuts, cap nuts, set nuts, etc. We can supply these duplex 2205 nuts with minimal lead time.

2507 has Good general corrosion resistance, Suggested for applications up to 600¡ã F, and Low rate of thermal expansion.

Duplex stainless steel, alloy 2205 was designed as comprising 22% chromium, 3% molybdenum, and 5-6% nickel nitrogen. Alloy 2205 combines the desirable aspect of properties of both austenitic and ferritic grades.

ASTM A815 specification covers two general classes, WP and CR, of wrought ferritic, ferritic/austenitic, and martensitic stainless steel fittings of seamless and welded construction. Class WP fittings are subdivided into four subclasses: Classes WP-S, WP-W, WP-WX, and WP-WU. The material for fittings shall consist of forgings, bars, plates, or seamless or welded tubular products.
Teel Industry has grown in the past few decades and there are a variety of products available in the market. ASTM A815 UNS S32750 Pipe Fittings are one of those products and are available in various sizes, shapes, and dimensions. ASTM A815 UNS S32760 Pipe Fittings are designed to be resistant to corrosion and are said to have perfect weldability. These Super Duplex S32750 Buttweld Fittings are resistant to erosion corrosion and fatigue. They have a mixed microstructure of 50% austenitic and 50% ferrite.

Alloy 2205 (UNS S32305/S31803) is a 22% chromium, 3% molybdenum, 5-6% nickel, nitrogen alloy duplex stainless steel plate that, in addition to high strength and excellent impact toughness, also has high general, Localized and stress corrosion resistance.

ASTM A479 Duplex Stainless Steel 1.4462 Bolts have excellent resistance to stress corrosion cracking, as well as excellent resistance to localized corrosion, including intergranular, pitting, and crevice corrosion.

A butt weld pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow change in direction or pipe diameter, or branching or ending.

This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, …) in a safe and efficient manner, over short or long distances.

In order to convey the pipeline, it is necessary to remove the straight hose in the pipeline. When using various pipelines, various pipelines must be used. When the pipeline is used, the elbow must be used to change the size of the pipeline. When bifurcating, the three-way pipe The flange connection used when the joint is used with various pipe joints, in order to reach the long-distance transmission pipeline, in order to reach the thermal expansion and cold contraction joint or effective connection aging of the pipeline, the long-distance expansion and cold contraction joint is used for the connection of the pipeline. , In the connection of various instruments, there are also the connectors and plugs of the instrument phase.

The round and hollow pipes are usual ones. In addition to the Duplex Stainless Hollow Pipes and the Duplex Steel Round Pipes there are square, rectangular and hexagonal pipes available in the market.

Stainless Steel Duplex SAF 2205 Hex Bolts are used in machinery and construction and can be used with nuts or threaded holes. Since they can be tightened with a wrench, fully threaded hex bolts are specially designed to work more efficiently. Additionally, 2205 hex bolts are stronger than standard stainless steel, meaning they can be used for jobs that require high workloads and good corrosion resistance.

The ASTM A182 F51 flanges refer to standard or non-standard flanges manufactured in accordance with ASTM A182 Grade F51, which is designated with UNS number S31803.

Duplex-grade stainless steel alloys have ferritic/austenitic properties, giving these materials superior strength and excellent resistance to oxidation.

The advantage of the dual-phase structure is that it combines the advantages of ferritic alloys (resistance to stress corrosion cracking and high strength) with the advantages of austenitic alloys (ease of manufacture and corrosion resistance).

Duplex stainless steels are approximately 50% ferrite and 50% austenite for optimum strength and corrosion resistance.

Astm A182 F51 flange is made up of carbon, chromium, manganese, silicon, phosphorus, sulfur, nickel, nitrogen, molybdenum and iron.
