Materials for use in high temperature piping systems associated with petrochemical and power generation plants have to be alloys that can continue to have their mechanical characteristics intact after a long period of thermal exposure. Stainless Steel 310 Pipe is a chromium nickel steel grade, which is capable of resisting oxidation from high temperatures up to 1100°C in intermittent service. It is supplied in seamless, ERW, and EFW forms, and as per the requirements of ASTM A312, ASTM A213, and ASME B36.19. It is offered in sizes ranging from 0.5" NB to 36" NB in schedules 5S to XXS. Chromium content of the alloy enhances the resistance to scaling, while maintaining the carbon content at a low level leads to an improvement in creep strength.
When selecting materials for the expansion of refineries in Dammam, the aspect of stabilizing welding and cyclic heating is often given first consideration. Titanium-stabilized grades help cut down on the risk of carbide precipitation during the fabrication process as well as after long exposure at elevated temperatures in the range of 427°C to 816°C. Under these circumstances, Stainless Steel 321 Pipe offers an increased level of intergranular corrosion resistance because the titanium additions are usually at least five times the amount of carbon present. Besides meeting the ASTM A312 TP321 and ASTM A213 standards, the grade is generally available in seamless and welded forms with the possibility of dual certification and complete mill test documentation. Dimensions vary significantly, thus allowing support to pressure classes that are consistent with ASME B31.3 process piping codes.
The suppliers of these two grades that are both reputable and reliable can be found through pipingmaterial.sa, a B2B platform focused on Saudi Arabia, which is a place where genuinely interested buyers can meet the approved suppliers who provide traceable material certificates and project-specific compliance documentation.
