Liner
The inner strength for your pressure vessels

Thermoplastic liners

Our thermoplastic liners form the heart of many modern gas and liquid storage systems. As a thermoplastic inner liner, they ensure safety, leak-tightness and stability – perfectly tailored to your requirements. Whether hydrogen, CNG or other media: Elkamet supplies you with high-precision liners for the next generation of pressure vessels.

Liner
Where is our product used?

Practicality meets precision

Our liners are used wherever pressure vessels have to meet the most stringent requirements:

  • Hydrogen (H₂)
  • Compressed Natural Gas (CNG)
  • Nitrogen (N₂)
  • Other gases and liquids

Construction:
A thermoplastic liner serves as an internal, sealed shell and is combined with a fibre-resin wrap for mechanical reinforcement. The valve connections are realised via so-called boss parts and can also be provided in multiple versions if required.

We are experts in both – and can advise you on which to choose

Which method is the right one?

Rotational moulding

Rotational molding offers a high degree of design freedom for complex geometries and is particularly well-suited for larger components. It also allows for a wide variety of materials and is ideal for medium-volume production.
