ASTM A105 1-12 150# SORF 1.4565 X2CrNiMnMoN25-18-6-5 EN 10088 – 2 : 2005

ASTM A234 is the standard specification for pipe fittings of wrought carbon steel and alloy steel for moderate and high-temperature service. Carbon steel pipe fittings manufactured to ASMT A234 are usually furnished in butt-welding form in accordance with ASME B16.9 or ASME B16.49. There are two carbon steel grades: WPB and WPC, of which ASTM A234 WPB is mostly often used in pipeline industry. The A234 WPB butt-welding pipe fittings include elbows, bends, returns, tees, reducers, end caps, crosses, lap joint stub ends, nipples and couplings.
After forming at an elevated temperature, fittings are cooled to a temperature below the critical range under suitable conditions to prevent injurious defects caused by too rapid cooling, but in no case more rapidly than the cooling rate in still air. Heat treatment temperatures specified are metal (part) temperatures. Heat-treated fittings are to be treated according to paragraph 7 in Specification A960/A960M.

carbon steel ASTM A105 Flange are made up of carbon steel or mild steel material. The material composition can have carbon, manganese, phosphorus, sulfur and iron in the composition.

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.

Due to the high chromium content, these carbon steels have very good corrosion resistance.

ASTM A694 flanges are available in different grades such as F42, F52, F60, F65 and F70.

ASTM A106 is the same as ASME SA-106 and is the standard specification for carbon steel seamless pipe for high temperature service. It covers pipe sizes from NPS 1/8 [DN 6] to NPS 48 [DN 1200] with nominal wall thicknesses given in ASME B36.10M.

In the manufacturing industry, the production is done by obviously using the best possible quality of crude materials and alloys. It thus tends to offer various good attributes.

Forged pipe fittings refer to pipe fittings formed by forging in pipe fittings manufacturing industry. What is said here refers to the latter forging.

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 regular products of A234 WPB pipe fittings are elbows,tees,reducers,caps,cross.There are seamless and ERW A234 WPB pipe fittings,the seamless A234 WPB pipe fittings means the fittings are made from the seamless steel pipes,ERW means the fittings are made from ERW steel pipes.

This is called as the “center to face” distance and is equivalent to the radius through which the ASTM A234 gr WPB elbow is bent.

Carbon steel forgings, manufactured in accordance with ASTM A105, are generally used for piping applications. These forged carbon steel piping components (including flanges, fittings, and valves, etc) are used for ambient- and higher-temperature service in pressure systems. The A105N, which is designated with a suffix ¡°N¡±, denotes that the A105 forging shall be furnished in normalized condition. If the forgings are used for piping applications of ASME BPVC or ASME B31, the material shall be its identical equivalent of SA-105 or SA-105N. In short, the heat treatment of normalization distinguishes A105N from A105, or SA-105N from SA-105. ASTM A105 Flange is a specification of flanges. The specification can include different grades of stainless steel material made flanges. The flanges are of forged carbon steel and are meant for high temperature services.

These fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures.

ASTM A694 F46 forgings can be made from carbon, low alloy or alloy steel. Steel should be made by open hearth, electric furnace or basic oxygen process and should be fully deoxidized. Its forged flanges and forged fittings can be easily fabricated from ingots, blooms, billets, slabs or bars. All grades of ASTM A694 F46 shall be heat treated. Heat treatment of carbon steels and high strength low alloy steels can include normalizing, normalizing and tempering, or quenching and tempering. The heat treatment of alloy steel may include normalizing and precipitation heat treatment or quenching and precipitation heat treatment.

These flanges are best suited to the high demands imposed by the oil, gas and petrochemical industries

Usually, these applications are pressure systems, and it is seen in many instances, the ASTM A105 Threaded Fittings add value to said application.

Hex bolts are used to fasten two or more parts together to form an assembly either because it cannot be manufactured as a single part or to allow for maintenance and repair disassembly. By definition “A Bolt is a headed and externally threaded mechanical device designed for insertion through holes in assembled parts to mate with a nut and is normally intended to be tightened or released by turning that nut.” When used with a preformed internally threaded (tapped) hole, the hex bolt’s head is turned to tighten, which technically makes it a screw (see our Tech Data section for a discussion regarding the differences between bolts and screws). Hex bolts are also known as: hex head bolts, cap screws, hex cap screws, hex head cap screws, machine bolts, hex machine bolts, hex head machine bolts and, if fully threaded, tap bolts, hex tap bolts and hex head tap bolts. A hex bolt is often differentiated from a hex cap screw by its underhead bearing surface: if it has a circular boss, called a washer face, it’s a hex cap screw¡ªif it doesn’t then it’s a hex bolt.

ASTM A234 WPB Fittings are made up of different material grades.ASTM A234 WPB WPC WP5 WP9 WP11 WP22 Fittings Specification
ASTM A234 (ASME SA234) is standard specification of carbon and alloy steel pipe fittings for moderate and high temperature services.

Carbon steel A350 LF2 flanges have excellent corrosion resistance. Carbon steel A350 LF2 threaded flanges have excellent strength and excellent machinability.

Carbon steel forgings, manufactured in accordance with ASTM A105, are generally used for piping applications. These forged carbon steel piping components (including flanges, fittings, and valves, etc) are used for ambient- and higher-temperature service in pressure systems. The A105N, which is designated with a suffix ¡°N¡±, denotes that the A105 forging shall be furnished in normalized condition. If the forgings are used for piping applications of ASME BPVC or ASME B31, the material shall be its identical equivalent of SA-105 or SA-105N. In short, the heat treatment of normalization distinguishes A105N from A105, or SA-105N from SA-105. ASTM A105 Flange is a specification of flanges. The specification can include different grades of stainless steel material made flanges. The flanges are of forged carbon steel and are meant for high temperature services.

Steel flanges provide an easy access for cleaning, inspection or modification. They usually come in round shapes but they can also come in square and rectangular forms. The flanges are joined to each other by bolting and joined to the piping system by welding or threading and are designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.

A flange can be a plate for covering or closing the end of a pipe. This is called a blind flange. Thus, flanges are considered to be internal components which are used to support mechanical parts.

ASTM A420 WPL6 Pipe Fittings are one kind of butt welding pipe fittings,they are commonly produced from the steel pipes of ASTM A333 Grade 6.

The ASME SA 234 Gr WPB Pipe Elbow and other fittings can come in different dimensions according to the ASME/ ANSI B16.9 and B16.28 standards.Common use material are ASTM A234 Grade WPB, WPC, WP5, WP9, WP11, WP22 and WP91. It covers the butt-welded pipe fittings of Elbow, Tee, Reducer, Cap and Cross, and some socket welding, threaded pipe fittings.

The amount of other elements that may be present in stainless steel is immeasurable compared to carbon steel. The most notable feature of stainless steel is that it is not easy to corrode or rust. Avoiding corrosion is a unique property of steel, as most mild steels are primarily made of iron, which rusts quickly when exposed to conventional oxygen-containing atmospheres.

Often the angle of elbow is 90 degrees but there are different types of elbows with different angles as well. The Carbon steel welded pipe fittings are also one of the cost efficient methods to apply with other types of steel.

Carbon steel nut and bolt grades are divided into three different categories based on the carbon content of mild, medium and high carbon steels. Mild steel hex bolts are the most widely used category of all carbon steel groups. Mild steel threaded bolt alloys typically contain less than 0.25% carbon by weight. Since this type of carbon steel bolt cannot be hardened by heat treatment to promote the formation of martensite, the alloy is cold worked.

ASTM A234 standard steel pipe fittings have been widely applied in pipeline systems, it includes carbon and alloy steel material.ASTM A234 WPB Fittings are made up of different material grades.

ASTM A105 is a standard material specification for forged carbon steel piping components including bolts, nuts, studs and other fasteners to standard or custom dimensions, for use in ambient and higher temperature service in pressure systems.

To strengthen and harden the steel and cast iron alloy Carbon Steel Slip On Flanges are passed through a process known as quenching.

The ASTM A420 Grade WPL6 can be seamless, welded or fabricated. There are different types of the fittings such as the unions, plugs, couplings, bends, caps and elbows.
