Beschreibung
Zusammenfassung:	The invention relates to production of long spiral-welded large polymer products, as required for pipelines production, chemical, oil and gas and petrochemical industries, agricultural complex and utility services. The object of the invention is to create variants of spiral-welded polymer product with a cellular wall, having the internal or external, or internal and external uniform smooth walls with little material consumption, weight and cost. It should allow making products on site due the use of a thin-walled, lightweight, flexible profile. The object is solved owing to fact that a long hollow thermoplastic profile is used in spiral-welded polymer products, wherein the cross-section of the profile has a form of a closed geometric figure with a convex part having essentially the semi-ring shape and flat part that are connected each other, forming the convex and flat parts of the external surface of the profile, respectively.
