Safety engineering requirements of design, construction, manufacture

Applying scopes:

This standard has been applied for:

Pressure vessels have working pressure which larger than 0.7 KG/cm2

Tanks, cylinders used for containing, transporting, LPG, or substances, which have working pressure

larger than 0.7Kg/cm2 or liquid, powder or solid substances without pressure but when discard having

pressure larger than 0.7 KG/cm2.

Bottle used for containing, transporting LPG, dissolved gases which have working pressure larger than

0.7 KG/cm2.

Electricity boilers have working pressure larger than 0.7 KG/cm2 or electricity autoclave have

temperature larger than 115oC.

This standard doesn’t apply for:

Vapor or water warming system.

Vessel have volume smaller than 25 liters if P.V< 200. P= pressure (Kg/cm2) - V= Volume (liter).

Compulsory responsibilities of people concerning design, manufacture and using pressure vessels.

Designers must have responsible for identify structure, calculation and selecting materials for each part

of vessel, establishing diagrams of equipment, measuring, monitoring and safety devices that complying

with this standard. In addition, designers have responsible for considering and agreeing these designing

changes of manufacturers.

Manufacturer must have responsible for setting up technology manufacture procedures in accordance

with requirements of designers, organizing quality tests in each stage during manufacturing processes

and also have responsible for their products’ quality according to designing and this standard.

When selling products, manufacturers must grant these technical records for buyer as follows:

History of vessel: 02 volume.

Structural drawings of vessel have adequate main dimensions and nozzles.

Manual instructions on erection and usage.

Testing report after manufacturing.

Technical documents must be maintained at least five years at manufacturing sites.

The pressure vessel vendors must have responsible for the quality and the parameters of vessels at the

working pressure that were announced in selling vouchers. Vendor must give warranty to vessel

according to state laws and at the same time they must supply technical records according to article 4.2

of this standard.

When the vendors lack of technical records in accordance with stipulation at article 4.2, they can ask
