ASTM A333 Gr.1 Low Temperature Seamless Medium Carbon Steel Boiler And Pressure Vessels Tubes
1. Product Description
ASTM A 333 Gr.1 low temperature conditions seamless steel flue pipes are suitable for low temperature, which's conditions of - 45-195, including low-temperature pressure vessels, low-temperature pressure pipes, low-temperature heat exchangers, etc. There are 11 grade levels of materials in this standard. Now we mainly make GR1 and GR6 levels, and other grade levels because there are very few customers, if necessary, we need to independently confirm whether they can be produced. In addition, besides chemical analysis inspection and physical test, the standard steel pipe shall also be exam the impact test under - 45 °C environment.
ASME SA333 Gr.1 series steel pipes for export can be painted and marked on the surface, threaded and chamfered on both ends, with pipe caps and protective covers on both ends, and can be packed in various ways to ensure the safe transportation of products.
Our products sell well all over the world, and high quality products are unanimously recognized by customers.
2. Industrial application
ASTM A333 Gr.1 Seamless carbon steel tubes are suitable for low temperature condition industries purpose. The temeperature are normaly between -45 to -195 degree centigrade.
