Butt Weld Pipe Fittings

It is well known that ASTM A234 steel pipe fittings are used in pressure piping and pressure vessel fabrication for service in medium and high temperature. Fitting materials in this standard include killed steel, forgings, bars, plates, seamless or fusion welded tubular products with filler metals added.

The source raw material for ASTM A234 WPB steel pipe fittings may come from steel pipes such as ASTM A106 Gr.B and C. Also from steel plates like ASTM A285 Gr.C, ASTM A516 Gr 70, ASTM A572 etc.

ASTM A234 includes both seamless and welded pipe fittings, seamless steel pipe fittings refer to pipe fitting raw materials made from seamless steel pipes and pipes; therefore, welded steel pipe fittings cover fitting raw materials from welded steel pipes.

The manufacturing process of pipe fittings includes forging and forming operations. As well as pressing, hammering, piercing, extrusion, upsetting, rolling, bending, fusion welding and machining. Or a combination of two or more of these operations.

ASTM A234 carbon steel pipe fitting grade, alloy steel pipe fittings are made of chromium, molybdenum, nickel alloy, Hastelloy, Monel, Inconel and other alloy elements, with higher pressure rating, better strength, good corrosion resistance resistance and longer durability. Widely used in oil and gas pipelines, chemical industry, power plants, nuclear power plants, servers and other fields.

ASTM A234 alloy steel pipe fittings include long and short radius alloy steel elbows, alloy steel eccentric and concentric reducers, alloy steel caps and crosses, alloy steel joints, alloy steel tees, alloy steel joints, alloy steel caps and other forms. It is available in seamless, welded and fabricated types.

Different pipe fittings have different materials. The main difference between carbon steel pipe fittings and stainless steel pipe fittings is steel, and stainless steel belongs to alloy steel.

Tensile Strength and Weight – Both carbon steel and stainless steel are quite high in tensile strength and weight. Piping applications are based on the requirements of the manufacturing program for the application. The ductility of the material depends on the gauge at the time of extrusion, which is similar for both alloys. Typically these fittings are milled; metalworking can expect similar results between the two materials. Manufacturers want materials that have the required ductility, such as adding aluminum to stainless steel, because of its corrosion resistance.

Knowing the finish of these steels can be helpful if your pipes are visible and appearance is on the list of considerations. Stainless steel is usually glossy and can retain that gloss if exposed to weather and other factors. Carbon steel, on the other hand, is darker in color and usually has a matte finish when painted. Unfortunately, it can also rust and look bad if left exposed. Galvanizing is also an option.

Carbon steel pipes are a popular choice for a variety of applications. Ventilation and steam ducts, municipal ducts and sewage ducts are usually made of carbon steel. It helps if you consider additional properties that may be required in chemicals or temperature. The above details can help you determine which steel is right for you.

ASTM A234 is a standard specification for steel pipe fittings, including carbon and alloy steel materials for medium and high temperature service. It covers seamless and welded types of steel fittings. Steel pipe fittings are used in the manufacture of pressure pipes and pressure vessels. These fitting materials include killed steel, forgings, bar, sheet, seamless or HFW (fusion welded) pipe products with added filler metals.

Generally speaking, carbon steel pipe fittings and flanges are widely used in applications that do not require higher corrosion resistance materials such as stainless steel and nickel alloys. Carbon steel products are easy to corrode and rust when exposed to water.

Choosing between stainless or carbon steel is a question many designers, engineers, mills and industry workers face at some point. Both carbon steel and stainless steel pipes are good choices for a variety of purposes. However, if we dive into the basics of various steel alloys and their uses, you must better determine the type of steel that fits your application needs.

ASTM A234 WPB Elbow is a standard specification for Piping Fittings of Wrought Carbon Steel and Alloy Steel suitable for for Moderate and High Temperature Service.

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.

Carbon steel is a base steel composed of carbon and iron. It may contain other substances in unmeasured quantities or in trace amounts. Carbon steel is classified according to the carbon content mixed with iron. Medium and low carbon steels may have a carbon content of less than 0.3%, while high carbon steels may have carbon content as high as 2%. The percentage difference in content is usually chosen based on solderability. Carbon is known for its ability to withstand high temperatures and strength/stress.

Grade WPB is the most common material for medium and high temperature pipelines in these standards. W stands for “weldable,” P for “pressure,” B for “grade b,” and Y for “yield strength.”

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 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.

Our Carbon Steel Butt Welded Pipe Elbow is a carbon steel pipe solution made of forged carbon steel and is mainly used in the high temperature service range.

When you need to decide on a metal, the first deal breaker is determining whether it can perform with some corrosive media, such as brine or processing chemicals. If so, you will need a less reactive metal. It’s probably best to choose stainless steel tubing, but double-check the properties of the materials you’ll be using to see if they’ll react.

Carbon steel butt welded seamless pipe fittings are the most commonly used fittings. We have a large inventory of carbon steel welding fittings such as elbows, caps, reducers, tees, couplings, unions, and more, ideal for pressure vessels as well as chemical and acid manufacturing.

Carbon steel pipes are known for their ability to withstand high temperatures and are ideal for steam pipes. However, if you are trying to work in extreme climatic conditions (for example, transporting cryogenic liquids), you must use a different grade of pipe.

We are also shareholders of carbon steel pipe fittings, such as carbon steel butt welding elbows, butt welding carbon steel crosses, butt welding carbon steel tees, butt welding carbon steel end caps, carbon steel butt welding short pipe ends, etc.

Fortunately, both carbon steel and stainless steel are very affordable compared to nickel alloys. Carbon steel pipes are often listed as the cheapest steel for plumbing, but stainless steel is often a close second. It allows you to choose the right material that best suits your project without major consideration of cost.
