Abstract
In order to provide a tubular moulding with a wall, which has high compressive strength and high mechanical stability with good temperature resistance and good chemical resistance, it is proposed that the wall comprises a composite, which comprises a plastics material layer, which is formed from a material containing a fluoropolymer material, and a reinforcement layer.
Claims54
Tubular moulding with a wall, wherein the wall comprises a composite, which comprises a plastics material layer, which is formed from a material containing a fluoropolymer material, and a reinforcement layer.
Method for producing a tubular moulding, comprising the following method steps:
- arranging a hose, which is formed from a material containing a fluoropolymer material, and a support hose in a blow mould;
- heating up the blow mould to a forming temperature;
- producing a pressure difference between the interior of the hose and/or the interior of the support hose, on the one hand, and the region of the interior of the blow mould located outside the hose and the support hose, on the other hand, so that the hose and the support hose are pressed against the inner wall of the blow mould and together form a moulding with a wall, which comprises a composite of the hose and the support hose;
- removing the moulding from the blow mould.
Method for producing a tubular moulding, comprising the following method steps:
- producing a tubular moulding blank made of a material containing a fluoropolymer material;
- connecting a support hose to the moulding blank to form a rigid bond in at least one composite portion, wherein the support hose, in at least one non-composite portion, is not connected to the moulding blank to form a rigid bond.
