Since its invention, stainless steel has been chosen widely by various industries. Added with chromium, this metal has a resisting capacity against corrosion. Stainless steel round bar manufacturer says that one can demonstrate resistance in reduced acids and against pitting attacks in chloride solutions. Stainless steel needs minimum maintenance requirements and the familiar shine makes it an excellent choice for pipes. Stainless Steel Pipe Fittings are available in a wide range of choices, such as seamless or welded pipes. 

If the composition is changed, steel grades like 2207 stainless steel can be used in different sectors. Steel pipes are used regularly in many different industries. Here we discuss various types of stainless steel pipes and Stainless Steel Flanges. We classify stainless steel products based on the manufacturing methods and standards used to produce them. 

Stainless steel pipe varieties based on their production method

The method of manufacturing welded pipes and Stainless Steel Forged Fittings through continuous plate or coil rolling where the plate or oil is rolled in a circular section using a roller or any bending equipment. The filler material is employed in large-scale manufacturing. When compared to seamless pipes, welded pipes are less expensive and come with a more cost-intensive production method. 

These manufacturing methods, especially welding methods are significant for stainless steel pipes. Welding methods usually come in abbreviations and it is essential to understand the abbreviations. There are different welding methods and techniques. The most popular welding methods used to manufacture stainless steel include:

• ERW– Electric resistance welding 
• EFW– Electric fusion welding 
• SAW– Submerged arc welding
• HFW– High-frequency welding 

Seamless method for manufacturing stainless steel pipe includes electric resistance welding, where the metal is rolled throughout its length. Using metal extrusion, Carbon Steel Round Bar manufacturers can make any length of seamless steel pipes. ERW pipes come with joints that can be welded over their cross-section but at the same time, joints in the seamless pipes run the length of the pipe. Welding has no role in seamless pipes because the entire manufacturing process is accomplished through a strong round billet. Seamless pipes accomplish their wall thickness and dimensional standards in different diameters. It does not have any seams on the body of pipes, hence these pipes can be employed in high-pressure applications such as refineries, oil and gas transportation, and industries. 

Based on metal grades 

Stainless steel contains a mechanical composition that can greatly influence the mechanical elements and application areas of the end products. This is why they are classified in terms of their chemical compositions. When it comes to identifying the grade of a particular stainless steel pipe or Carbon Steel Flanges, we have to find out the different types of nomenclatures. Some of the commonly used standards for steel pipes are EN, DIN, and ASTM grades. You have to check and ensure that your chosen stainless steel variant possesses the expected grade and quality. 

Thus, hope you get a clear idea of the types of stainless steel and how it is classified based on different measurements and standards.
