<p>The clamp has an annular body formed from upper and lower half shells (1, 2), and two contact surfaces (13, 14) formed in the half shells such that the contact surfaces are turned towards each other in an area of a joint (12). The joint is formed between the half shells in an assembly condition. The contact surfaces carry a deformable sealing element (17), an outer sealing element and an inner sealing element. The sealing elements are made of polyurethane sealing foam. The upper half shells are made of thermally insulating material i.e. polyurethane-hard foam.</p> |
