Abstract
Lining material is pressed or drawn in pieces between two spaced joints in the pipe, so that o.d. of the lining agrees with the i.d. of the pipe. The individual pieces are joined by polyfusion so that they form a continuous length corresponding to the distance between two joints. Specif. the lining is an easily polyfusible, plastics-elastic materials, pref. a polyolefin, esp. low pressure polyethylene.
