Seamless carbon pipes with suitable specifications are utilized for high-temperature services. For example, as American pipe items, the entire spectrum of pipe is offered. Unlike other standard bodies, ASTM includes almost all types of pipes. Stainless steel pipes and fittings are subject to over 100 standards. This organization has currently served 12000+ standards that are utilized in businesses all around the world. ASTM International provides service standards and industrial materials for a wide range of industries. It is also an accurate saying for stainless steel pipes.ĪSTM is an abbreviation for the American Society for Testing and Materials. The buyer must first grasp the fundamentals of various industrial specifications for their projects, before actually doing the purchasing operations. The manufacturing and testing results may differ due to differences in various organization standards for a wide variety of application ranges. It is a classic saying that industry and standards are closely tied. A part of a reference table for stainless steel pipe materialsĭifferent Types Based on ASTM Specifications The table below gives a useful overview of these different standards. One can consult a cross-reference table to find equivalent grades. The most used standards when designating steel pipes are DIN (German), EN, and ASTM grades. However, while trying to find out the grade of a specific stainless steel pipe, various types of nomenclatures can be encountered. ![]() So, it is no surprise that they can be classified in terms of their chemical compositions. The chemical composition of steel overall has a great influence on end-products mechanical properties and application areas. Difference between seamless and welded pipes, in terms of their production method and appearance Stainless Steel Pipe Types – Based on Alloy Grades In varied diameters, the seamless pipes were completed to the wall thickness and dimensional specifications. Since there is no seam on the body of the pipe, these pipes are utilized in high-pressure applications such as oil and gas transportation, industries, and refineries.įigure 2. ERW pipes have joints that are welded along their cross-section, whereas seamless pipes have joints that run the length of the pipe. There is no welding in seamless pipes since the whole production process is done through solid round billet. Seamless pipe of any length may be manufactured via metal extrusion. There are also seamless types of stainless steel pipes in markets. In more detail, following the production of electric resistance welding, metal is rolled throughout its length.
