Steel is a metal called a base alloy. Alloys are two or more natural metal elements fused together to form a unique metal. When we talk about steel we are talking about a metal alloy which is a mixture of iron or at least one other metal. Most types of steel have several metals mixed in, although their amounts may vary.

Pipe bending methods will vary based upon the metals used.

A 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.

304 stainless steel is the most common stainless steel. The steel contains both chromium (between 18% and 20%) and nickel (between 8% and 10.5%)[1] metals as the main non-iron constituents. It is an austenitic stainless steel.When it comes to uses, SS304 can be found in kitchen sinks and other appliances such as toasters and microwave ovens. SS304 is also used to make pressure vessels, wheel covers as well as for building facades.

Stainless steel fittings are made of corrosion-resistant 304 stainless steel for durability and dependability. Suitable for diverse industrial applications such as vibration, high pressure or corrosive conditions.

The alloy has great mechanical properties at subzero temperatures, and with a melting point of 2370¡ã ¨C 2460¡ã F, products can be used at temperatures up to 1000¡ã C.

ASTM A234 is the standard of pipe fittings material,it indicates the materials properties of different kinds of carbon steel and alloy steel,WPB is one of the steel grade in this standard.W means weldable,P means pressure,B is grade b,refer to the minimum yield strength,like the astm A106 A53,Gr.B or API 5L Gr.B.A234 WPB is the most common carbon steel pipe fittings material.

Duplex S31803 stainless steel butt welded pipe fittings are used in desalination, boiler manufacturers and brewing tanks. They are generally lower cost and have a lower percentage of alloying elements. They are suitable for ASTM A 815, A812 and ASME SA 815, SA 812 specifications.

Superior resistance to hydrochloric acid, aluminum chloride catalysts and other strongly reducing chemicals. Excellent high-temperature strength in inert and vacuum atmospheres.

In addition to the properties of 304, 316 stainless steel long and short tube ends have increased corrosion resistance due to the addition of molybdenum to their composition. There are duplex steel short end flanges and fittings.

304 fittings are standard “18/8” stainless steel; it is the most versatile and widely used stainless steel available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics.

This nickel alloy resists the formation of grain-boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in the as-welded condition.

Incoloy 800 Street Elbow is designed with female threads on one end and male threads on the other end. It allows pipes to connect with other pipes at an angle. The main advantage of this elbow is that it can be connected directly to other fittings without the need for fittings or short connecting pipes.

The advantages of stainless steel butt-weld end caps include permanent leakage prevention, increased strength and power of the pipeline structure, and reduced pressure loss, but the stainless steel cap is firmly fixed and cannot be loosened like a blind man to enter the pipeline flange.

Our ASME SA403M SS 304 caps are highly demanded by the printing and textile industries for their versatility and excellent solderability.

Titanium is also a ductile metal, especially in an oxygen-free environment.

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.

What makes this material a cost-effective alternative is that the nickel content that manufacturers use to produce dual-phase steel butt-welded pipe fittings is lower than that of super-duplex steel. While the reduction in nickel content gives the metal lower mechanical properties, the higher molybdenum and chromium content almost makes up for the lack of nickel in duplex stainless steel fittings.

Typical application for MONEL K500 which takes advantage of high strength and corrosion resistance are pump shafts, impellers, propeller shafts, valve components for ships and offshore drilling towers, bolting, oil well drill collars and instrumentation components for oil and gas production. It is particularly well suited for centrifugal pumps in the marine industry because of its high strength and low corrosion rates in high-velocity seawater.

Grade 2205 is the most widely used duplex stainless steel grade. Fittings of this grade finds applications due to both their excellent corrosion resistance as well as their high strength.

We manufacture premium duplex 31803/32205 fittings with many key properties such as high resistance to corrosion fatigue, stress corrosion cracking, especially chloride stress corrosion cracking, erosion, excellent workability and weldability.

Grade WPB fittings made from the steel pipes or plates maximum C is 0.35%.

Duplex UNS S31803 butt welded pipe fittings are duplex ferritic austenitic 22% chromium, 3% molybdenum, 5% to 6% nickel alloy stainless steel. Duplex UNS S31803 butt welded pipe fittings are formed according to the crystal structure of stainless steel.

Inconel Tube Fittings can be easily elongated by 40% and still possess excellent workability. These fittings have a melting point of about 1413 degrees C and have a long service life. The Inconel 600 Buttweld Fittings can be produced by hot or cold rolling processes.

These fittings commonly used in pressure pipelines and pressure vessel/tanks at lower temperature.

ASTM A403 WP316 Elbows are used to reduce pipe size from larger to smaller sizes. Reducers are one of the most commonly used fittings, as the complexity of large pipes often requires size reduction.

ASTM A234 Pipe Fittings include Tee, Concentric reducer, eccentric Reducer, 5D/6D bend, elbow, unions, plugs, cross tee, pipe cap and nipple, ect for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures.

The fittings are also hard with a Brinell hardness sore of 210HB maximum. These can also operate under very high temperatures up to 870 degrees Celsius.

For equal tee/straight tee, the center-to-end dimension of branch is same with the run, while for reducing tee, the center-to-end dimension of branch is smaller than the run to obtain the desired flow and pressure through the piping system.
