Code for design of metallic and non-metallic expansion joints
The design and calculation of expansion joint products are strictly according to the technical specifications of American Association of Expansion Joint Manufacturers Standard "EJMA", GB/T12777-2008 "General Technical Conditions for Expansion Joints of Metal Corrugated Pipe", GB 16749-97 "Corrugated Expansion Joints of Pressure Vessels", GB/15700-1995 "General Technical Conditions for PTFE Wave Compensator" and other standards, and computer-aided optimization design is carried out; The nominal diameter of the corrugated compensator series products produced by the company ranges from φ 32mm to 12000mm, which can meet the design and manufacture of any rectangular cross-section size. The working pressure ranges from "vacuum" to 10Mpa, and the design temperature is-196℃-1300℃, which can meet the needs of various projects at home and abroad.
Products are widely used in electric power, desulfurization and environmental protection (thermal power, nuclear power, hydropower, thermal power, etc.), iron and steel metallurgy, oil refining and oil storage and transportation, chemical industry (sulfuric acid, hydrochloric acid, phosphoric acid fertilizer, ethylene, etc.), cement, urban central heating, high-rise buildings, military industry, food light industry, electronics and other industries.
