ASTM A312/A312M Hot Rolled TP321 Seamless Round Tube Price TP304 TP304H Welded SUS316 316L Stainless Steel Pipe Reliable Supplier Factory 63.5x3.0mm

ASTMA312/A312M is a specification developed by the American Society for Testing and Materials (ASTM) specifically for the manufacturing requirements and mechanical properties of seamless, welded, and cold worked austenitic stainless steel pipes. This standard covers pipes with diameters ranging from 1/8 inch (6.4mm) to 30 inches (760mm), and thicknesses ranging from standard (CH 5S to XXS (SCH XXS)), meeting the different needs of different industries for stainless steel pipes.
Common brand: TP304,TP304L,TP304H,TP310S,UNS S31254,TP316,TP316L,TP321,TP321H,TP347,TP347H,UNSN08810,UNSN08811, Waiting for the brand.
Common specifications: outer diameter 6.4mm~1626mm, wall thickness 1.2mm~150mm
Production method: welding, delivery status: heat treatment+acid pickling.
manufacturing process
The manufacturing process of ASTM A312 stainless steel welded pipes mainly includes raw material preparation, forming, welding, heat treatment, and surface treatment. The raw materials should be selected from austenitic stainless steel plates or strips that meet the standard requirements, and after pre-processing such as cutting and cleaning, they should be sent to the forming machine for rolling or compression molding. The formed pipe blank needs to be welded using automatic welding, manual welding, or combination welding methods to ensure the quality of the weld seam. After welding is completed, heat treatment is also required to eliminate welding stress and improve the overall performance of the pipeline. Finally, the inner and outer walls of the pipeline are subjected to surface treatments such as mechanical polishing, degreasing, acid washing, and cleaning to achieve the specified surface finish requirements.
quality control
To ensure that the quality of stainless steel welded pipes meets standard requirements, manufacturers need to implement strict quality control measures. Firstly, the raw materials need to undergo strict inspection to ensure that their chemical composition and mechanical properties meet the standard requirements. Secondly, in the manufacturing process, strict control of each process is required, such as forming accuracy, welding quality, heat treatment temperature and time, all of which must meet the process requirements. At the same time, it is necessary to conduct comprehensive testing and experimentation on the finished product, including mechanical performance testing, intergranular corrosion testing, hydrostatic testing, etc., to ensure the safety and reliability of the pipeline in actual use.
application area
ASTM A312 stainless steel welded pipes have a wide range of applications. In the chemical industry, stainless steel is widely used in pipeline systems for manufacturing, storing, and transporting chemical substances due to its excellent corrosion resistance, which can effectively prevent corrosion and pollution of pipelines by chemical substances. In the oil and gas industry, stainless steel pipelines can withstand harsh conditions of high pressure and high temperature, while also possessing good wear resistance, making them an important tool for drilling, mining, and transporting oil and gas resources. In addition, in the food and pharmaceutical industries, stainless steel pipes have become a key component in the production process due to their non-toxic, odorless, non polluting, and easy to clean and disinfect characteristics.
