Shanghai Dragon Industrial Engineering's Explosion Venting Bolts Certified to American FM Standard


2018-12-03  |  Class : 螺絲

The explosion venting bolts developed by Shanghai Dragon Industrial Engineering (SDIE) passed the certification audit of American FM, a third-party inspeciton body. SDIE becomes the world's second and China's sole FM-certified company for its explosion venting bolts.

FM is one of the most stringent QC inspection bodies in the U.S. and represents the world's top level certification. It indicates to consumers that a product or service passes the inspection under American and international standards. Acquiring the FM certificate means the performance of SDIE explosion venting bolts is approved by a renowned third-party inspcetion body, recognized by global clients, and that the bolts are allowed for global sales and application.

Explosion venting bolts are used in hazardous chemicals warehouses, nuclear power plants, and industries including petrochemical, electronics, new energy, medical and military, where indoors explosion is a potential threat. They are used to ensure instantaneous accurate pressure relief from explosion venting doors/windows/walls/roofs, resolving issues of inaccurate pressure relief from calcium silicate explosion venting walls/roofs.

Explosion venting bolts can release pressure via quantizing explosion venting pressure. Fire-proof construction design regulates that explosion-prone factories must have pressure relief facilities. The shank of explosion venting bolt is specially coated for chemical corrosion and rust resistance. The aluminum washer of the bolt is curved at a certain degree and attached with EPDM rubber from the bottom for water resistance. The load capacity of the bolt ranges from 30-70kg, adding more convenience to designing the bolt.
