Abstract
System for protecting machine parts, such as threads, from physical and chemical damage. The parts to be protected are cleaned, coated with a separating agent, and a mold is placed around them. A protective material is inserted in the interspace between the mold and pipe end. The protective material forms a tough, protective jacket. If desired, the mold can later be removed by means of a tear-open element or integrated weak spots. For the protection of pipe interiors, plastic material can be pressed into the end of the pipe such that it seals against the inside lining of the pipe.
