What standards do Mindreks Metall’s accumulator tanks comply with?

Mindreks Metall’s high-quality accumulator tanks are manufactured in accordance with specific production requirements. Mindreks Metall accumulator tanks come with a 5-year warranty.

When manufacturing tanks, we follow these principles:

• European Union Pressure Equipment Directive 2014/68/EU;
• the principles of good engineering practice, or SEP;
• the standard series of non-flammable pressure vessels, EN 13445;
• the EN ISO 3834-3:2021 welding quality standard;
• the EN ISO 9606-1 qualification standard for welders.

The Pressure Equipment Directive and Good Engineering Practice

The European Union’s Pressure Equipment Directive 2014/68/EU, also known as the PED, establishes requirements for the design, manufacture, materials, inspection, and safety of pressure equipment.

Mindreks Metall accumulator tanks are manufactured in accordance with good engineering practice (SEP), as described in Article 4, paragraph 3, of the directive.

Good engineering practice means that recognized technical principles are followed in the manufacture of the tank. Attention is paid to structural strength, suitable materials, the quality of welded joints, production control, and product traceability.

EN 13445 series of standards

EN 13445 is a series of European standards covering the design and manufacture of non-flammable pressure vessels.

The standard series includes:

• selection of materials;
• structural and strength calculations;
• soldering solutions;
• manufacturing;
• inspection and testing.

This provides a technical framework for assessing whether a tank is suitable for the specified capacity, pressure, and operating conditions.

EN ISO 3834-3:2021

The EN ISO 3834-3:2021 standard specifies quality requirements for fusion welding of metals.

It covers the entire welding process: work planning, materials, equipment, work instructions, employee competence, quality control, and documentation.

A controlled process helps maintain consistent weld quality throughout the entire production process.

EN ISO 9606-1

The EN ISO 9606-1 standard addresses the qualification of steel welders.

A welder’s competence is assessed through a practical test that takes into account the welding method used, the material, the thickness, and the working position. Qualified welders help ensure the strength and consistent quality of welded joints.

High-quality storage tanks with a 5-year warranty

The reliability of a accumulator tank is established throughout the entire manufacturing process. A well-designed structure, the right materials, high-quality welded joints, and thorough inspection are all essential.

Each accumulator tank has a model number, order number, and serial number. This links the finished product to its technical specifications and production documents and ensures traceability.

We offer a 5-year warranty on Mindreks Metall accumulator tanks. This reflects our confidence in the tanks’ design, materials, and manufacturing quality.
