コンプライアンス概要

この概要は現在英語のみで提供しています。

適用範囲

This standard is mandatory and applies to the design, manufacturing, testing, and inspection of non-metal atmospheric pressure tanks used in road tankers transporting liquid dangerous goods. It specifically covers tanks made of polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP), and glass fiber reinforced plastics (GFRP) with a working pressure of less than 0.1 MPa. This standard is not applicable to metal tanks, vacuum insulated tanks, military tanks, tanks with a volume greater than 20m³, or tanks carrying extremely or highly hazardous toxic media. It is intended for tanks permanently connected to a vehicle chassis or semi-trailer frame.

技術要求

The standard specifies comprehensive requirements for non-metal tank materials, including mechanical properties and corrosion resistance. For GFRP tanks, it mandates a multi-layer wall structure consisting of an inner surface layer, a secondary inner layer, a strength layer, and an outer surface layer, with specific resin content requirements for each. Design requirements include calculations for design pressure, design temperature, and allowable stress based on the specific plastic material used. The standard outlines formulas for calculating the minimum thickness of the tank body and heads, taking into account static and dynamic loads during transportation. Manufacturers must ensure the tank's design pressure is not less than the maximum working pressure and that the calculated thickness accounts for external pressure stability. Manufacturing processes are strictly regulated, covering plastic welding, rotational molding, and GFRP lamination. The standard requires non-destructive testing (NDT) for welds and laminated structures, including radiographic, ultrasonic, and penetrant testing, to ensure structural integrity. It also details the installation of safety accessories, such as emergency shut-off devices and venting devices.

試験方法

The standard mandates a hydrostatic pressure test as the primary method for verifying the tank's structural integrity, with the test pressure set to the tank's calculated pressure. For rotational molded PE tanks and GFRP tanks, mechanical property testing (tensile strength) is required using samples cut from the manhole area. Additionally, pneumatic testing is required for loading and unloading hoses, and specific NDT methods—radiographic for welded joints, ultrasonic for rotational molded tanks, and penetrant testing for nozzles and flanges—are specified to detect internal and surface defects.

よくある質問

What types of materials are covered under GB 18564.2-2008?

This standard covers non-metal tanks made from polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP), and glass fiber reinforced plastics (GFRP). It specifies different technical requirements and manufacturing processes for each material type.

What is the maximum working pressure allowed for tanks under this standard?

The standard applies to atmospheric pressure tanks with a working pressure of less than 0.1 MPa. Tanks operating at or above this pressure threshold fall outside the scope of this standard.

Are there specific temperature limits for the non-metal materials used in these tanks?

Yes, the standard specifies allowable temperature ranges. For PVC and PP, the range is -10°C to 50°C, while for PE and GFRP, it is -20°C to 50°C. The surface temperature of tank components must not exceed these limits under any circumstances.
