Abstract

Pipes with the defects of the welded joint (cavities, inclusions, brittle fracture) are studied, and their relationship with the characteristics of the feedstock is shown. Qualitative and quantitative indicators of the concentration of volatile substances of various fractions in the granules of polyethylene are obtained. The value of moisture absorption of carbon black concentrates used in the production of PE100 is determined.
