Dhina railway fastener are widely used in urban rail construction. In recent years, rail fasteners have been put into the field of railway and steel structures, and they are very popular and sought after Rail joints of railways are the source of vibration. In order to overcome this source of vibration and reduce the occurrence of rail joint diseases, the use of railroad track bolts and nuts is the best choice. They can eliminate the diseases of rail joints and increase the resistance of joints. Although the construction of railways is inseparable from the role of railway fasteners, not all specifications and types of railway bolts and nuts are suitable for railway construction. The strength of some ordinary railway fasteners cannot adapt to the vibration of high-speed rail, railway, and subway. All rail transportation requires high- strength railway fasteners. As railway construction continues to increase, the demand for high-strength railway fasteners around the world will also rapidly increase. As one of the leading railway fastener factories in China, DT can provide you with quality railway fasteners at great prices. Feel free to contact at any time. If you need any kinds of quality fasteners, please contact us, as a professional fastener factory, Datian is willing to offer you high quality products.

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: ●The 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; ●The 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: ●In 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. ●Selected materials (grades) include medium carbon alloy steels: 35CrMo (applicable temperature +100-525℃); 25Cr2MoV (applicable temperature>-20- -575℃); 42 CrMo (applicable temperature +100-525℃). The strength is between 690~890Mpa, that is to say, the medium carbon alloy steel is tempered at high temperature (550℃<=tempering temperature<=600℃) to obtain comprehensive mechanical properties to meet the service of high-temperature environment. ●Stainless steel materials selected are: 0Cr18Mi9 (applicable temperature -196--800 ℃); 0Cr17Mi12Mo2 (applicable temperature +196--800 ℃); the strength of stainless steel material obtained by solution treatment is between 690~890Mpa, and the performance level is A2- 70 A4-50 A4-80 grade. ●Using American standards, using stainless steel grades and materials: ASTM A193 B8 CL.2 (for temperature +196-525℃); A193 B8M CL.2 (for temperature +196- 525℃); A453660 (for temperature +29- 525℃); also includes A320L7 suitable for low temperature and high-pressure environment (applicable temperature -100℃). ●Special grade nut material (grade) can choose medium carbon alloy steel: 30CrMo, 35CrMo; guaranteed load There are many fastener manufacturers, but we are one of the best choices for you.
