3 Terms and definitions

There are no terms and definitions that need to be defined in this document.

4 General requirements

Under the specified operating conditions, the materials (including metallic materials and non-metallic materials) in contact with various process gases should have corresponding resistance. Chemical properties, mechanical properties and heat resistance. In the temperature range of -20℃~60℃, the performance of the material should be stable and should be able to meet the design function requirements of the equipment. For the interconnection of different types of materials, the contact area should take anti-corrosion measures.

5 Special requirements

5.1 Metal materials 5.1.1 Equipment using acetylene The material in the contact part of the equipment with acetylene (and the gas with similar chemical properties to acetylene), the content of copper in its composition (mass fraction) Number) should not exceed 70%, so as to avoid the formation of acetylene compounds and cause explosion hazards. Except for the nozzle and the outer surface of the neck tube of the welding torch, the material should not be used. Use surface copper plating process (or other similar process that enriches copper on the surface of the material). ......
