The "Chemical Industry" segment includes applications in the chemical and petrochemical industries.

Typical applications are heat-resistant and stainless steel bolted connections on

  • Compressors
  • Heat Exchangers
  • Pressure Vessels
  • Couplings
  • Split Lines
  • Anchorages

and many more.

On the one hand, existing plants can be upgraded – e.g. in the course of an overhaul – and on the other hand, new plants can be optimized during design.


HEICO-TEC® Tension Nuts – ideal replacement for standard nuts on pressure equipment subject to approval

A frequently encountered case in the chemical industry is the replacement of standard nuts (hexagon nuts) on pressure equipment subject to acceptance by Multi-Jackbolt Pretensioners. Here, the certified HEICO-TEC® Tension Nuts and Reaction Nuts available from stock offer a particularly economical and quick solution. They meet the requirements of the Pressure Equipment Directive (PED) as standard, while offering the familiar advantages of Multi-Jackbolt Pretensioners and do not require more space than standard nuts.

As an authorized sales partner in Switzerland for HEICO-TEC® Tensioning Systems, we will be happy to serve you with these products in such specific applications


If more stringent requirements are made, we develop the optimum bolted connection solution in close cooperation with the customer and ensure professional certification of the MJP in accordance with the Pressure Equipment Directive (PED), so that safe operation of the system is guaranteed. As far as technically possible, we supply standard MJP of the PM08, PM10 and PM12 series. Where necessary, special solutions in suitable materials are individually designed and manufactured for each application.

Radial Pretensioning Bolts (RPB) are the ideal solution on large couplings for the safe transmission of high torques.

All products are made of high-quality materials. Audits, tests, verifications and certificates of all kinds are possible.
