The safety valve is an important accessory for safety protection of pressure limiting and pressure relief on special equipment (boilers, pressure vessels, pressure pipes, etc.). Safety valves are generally installed directly on special equipment. His design, manufacture, installation, use, inspection, etc. must comply with the requirements of special equipment, because its operational reliability and performance are directly related to equipment and personnel. Safe and closely related to energy conservation and environmental protection.


Material selection: 

a. What welding will be carried out? - Austenitic steels are generally more weldable than the other types. Ferritic steels are weldable in thin sections. Duplex steels require more care than austenitic steels but are now regarded as fully weldable. Martensitic and PH grades are less weldable.

b. What degree of forming is required to make the component? – Austenitic steels are the most formable of all the types being able to undergo a high degree of deep drawing or stretch forming. Generally, ferritic steels are not as formable but can still be capable of producing quite intricate shapes. Duplex, martensitic and PH grades are not particularly formable.

c. What product form is required? – Not all grades are available in all product forms and sizes, for example sheet, bar, tube. In general, the austenitic steels are available in all product forms over a wide range of dimensions. Ferritics are more likely to be in sheet form than bar. For martensitic steels, the reverse is true.
