BS 7122 is a British standard that specifies requirements for the material, design, construction, and testing of the tanks of road tankers used for the conveyance by road of liquefiable gases under pressure. BS 7122 applies to steel tanks having manually and/or automatically welded circumferential and longitudinal seams.
BS 7122 may also be used as a specification for the materials, design, construction, and testing of portable tanks (e.g., the tanks of tank containers) with a capacity greater than 1 000 L. The requirements for the design, manufacture and testing of tanks are based on those specified for the construction category 1 component of BS 5500 and as far as possible are covered by direct cross-references to the relevant requirements in sections 2, 3, 4, and 5 of BS 5500, and to the requirements of other relevant British standards.
Note: BS 7122 does not cover vacuum insulated tanks and drums.
BS 7122 on welded steel tanks for transportation is useful for:
Welded steel tanks are a better choice as they last longer than the others, lifetime cost is the lowest and they require the least maintenance. They are durable, can be customized into the required shape and size, and are hygienic and eco-friendly.
BS 7122 provides its users with general specifications for the manufacturing process, the information that needs to be supplied by the manufacturer and purchaser, material identification, analysis, and test methods for inspection of performance and production. Using BS 7122 guidelines ensures quality assurance, safety, and protection for its users during transportation.
