ASTM and ASME

ASTM is stands for American Society of Testing and Methods and ASME specs American Society of Mechanical Engineers (ASME). They are very similar and identical; an important difference is that pipe meant for use in pressure systems sometimes requires different or additional quality tests before it complies with the ASME standard.

For example, A106 B is a spec published by ASTM (the ASME spec would be SA106 B). The “A” designates a ferrous material. ‘106’ is an arbitrary number that designates it as a seamless carbon steel pipe suited for high-temperature service. Then, grades (such as A, B or C) are assigned that indicate certain characteristics of the steel based on differences in its chemical makeup and mechanical properties.

AISI and SAE

The American Iron and Steel Institute (AISI) and the Society of Automotive Engineers (SAE) share a numbering framework to arrange steels. AISI/SAE standards just portray the chemical substance of a steel. They do exclude producing, heat treating or testing data.

Utilizing 1020 steel for instance, the principal digit communicates the steel as plain carbon steel. The second digit demonstrates there are no additional compounds. The last two digits show the steel has around 0.20 percent carbon content.

For another case, prominent steel in the Oil & guys industries is 4130. The ’41’ demonstrates the steel contains chromium and molybdenum compounds. The ’30’ shows the steel has around 0.30 percent carbon content.

Once more, AISI/SAE just order steels. For instance, a purchaser who says, “I require 100 feet of 4130” has not sufficiently given data. The buyer additionally needs to give specific production and testing information found in an ASTM or ASME spec to get exactly the pipe they need.

API

Pipe for use in the oil and gas industry are characterized by the American Petroleum Institute’s (API) standard. API 5L is the most widely recognized standard to which line pipe in the oil and natural gas industry is evaluated. Since that is just a standard, extra data is expected to ensure purchase orders are executed precisely.

API 5L is separated into PSL1 and PSL2 conveyance conditions; those conditions are additionally separated into pipe grades. For example Grade B, X42, X52, X65, and so on.

Carbon Steel

A type of steel that is created with a proportion of carbon added to iron, and is generally weak on its own. Because it continues relatively few alloying elements, in low concentrations moreover, it is often inexpensive. However, carbon steel holds high ductility, strength, workability and is safe and durable. Carbon steel accounts for 90% of total steel production. Not suitable for extreme conditions or high pressure, it is less resistant to deal with stress. Carbon Steel Pipes, structural in nature, are used in fluid, Oil and gas transmission, tools, ships, automobiles, etc. Under load, carbon steel pipes do not bend or break and come in grades A500, A53, A106, ,A252 as seamless and welded.

Alloy Steel

The name itself suggests what it holds in the name itself. Alloying elements make steel stronger v and therefore, resistant to stress and pressure, also weld and ductility. It contains total amounts between 1.0 to 50 % by weight to improve its mechanical properties. The most common alloying elements are nickel, chromium, manganese, copper,etc. Different industries depending on the uses, hold various combinations, according to set specifications. Alloy steel is generally utilized in the piping industry for extreme conditions, as well as in Oil and Gas and power generation, due to its toughness. Alloy Steel Pipes are around 1/8’ to 20” in size and possess schedules such as S/20 to S/ XXS. Alloy steel pipes are also used in Oil refineries, chemical plants petrochemicals, sugar mills, etc. Alloy steel pipes are customized and designed according to your needs and provided at affordable rates.

Stainless Steel

This belongs to that family of steel that does not rust. It contains between 10 to 20% chromium, the alloying element that prevents corrosion. Other alloys in Stainless Steel include manganese, silicon, nickel and molybdenum, that helps prevent further corrosion. The size of stainless steel pipes range from ½” to 36” , schedules 5 to. 80. Stainless Steel Pipes are used in industries where corrosion resistance is very important and requiring high strength, including ships energy, poles, water treatment, pharmaceutical and Oil and Gas applications. Available in types 304/304L and 316/316L. The former is highly corrosion and strength resistant, while 314 L has low carbon content and can be subjected to welding.
