FIELD: process engineering.
SUBSTANCE: invention relates to application of polyamide moulding mix for pipes, pipeline or sewers intended for transfer of heat carriers, water, oils, gas or the like. Method of fitting the insert in pipe or pipeline when pipe or pipeline ID is smaller than insert OD comprises decreasing the cross-section of insert made of polyamide moulding mix under action of external forces and fitting said insert into pipe. Invention covers also the pipeline with above described insert.
EFFECT: easy and tight fitting of insert in pipe, longer service life of pipelines.
