The standard refers to the American ASTM or ASME standard with new and unique technical clauses added, which is suitable for a type of petrochemical fasteners used in high temperature and high-pressure environments, including bolts, studs, nuts, etc.
The mechanical properties and materials specified in GB/T3098/8 "Mechanical Properties of Carbon Steel Fasteners Part VIII Heat-resistant Threaded Connections" are suitable for fasteners that can withstand high temperature, alternating loads, and to a greater extent. Be sure to tighten the axial force.
High temperature and high-pressure petrochemical fasteners - commodity fasteners and special fasteners
1. Common Commodity wind energy fasteners:
¡ñThe type and size of hexagon head bolts meet the requirements of GB/T5782, A and B grades. The mechanical properties of these petrochemical fasteners refer to the performance grades of carbon steel bolts according to GB/T3098/1 standard: A2-50, A4-50, A2-70, A4-70;
¡ñThe nut type conforms to GB/T6170 I-type nut and special nut (pipe flange nut). Its mechanical properties refer to the performance grades of carbon steel according to the GB/T3098/2 standard: grades 6 and 8; the performance grades of stainless steel nuts of GB/T3098/15 are A2-50, A4-50, A2-70, A4-70 ;
2. Special Petrochemical Fasteners:
¡ñIn order to be suitable for the conditions of high-temperature resistance, low-temperature resistance, and environmental corrosion resistance, formulate suitable special fasteners, such as full-threaded studs for pipe flanges, in accordance with the provisions of GB/T901. The dimensions of hexagon head bolts and nuts shall be carried out according to national standards.
