The range of welded pipe sheet piles manufactured at the enterprises of Trest Zapsibgidrostroy includes about 500 variants of profiles of steel pipe sheet piles that provide a maximum adaptation to the project conditions and are intended for construction of retaining walls under various climatic and geotechnical conditions.
The range of steel pipe sheet piles produced by Trest Zapsibgidrostroy is developed for pipe diameters 530, 630, 720, 800, 820, 1,020, 1,120, 1,420 and 1,620 mm with a wall thickness of 8, 9, 10, 12, 14, 16, 18 and 20 mm. A variety of the welded pipe sheet piles produced by Trest Zapsibgidrostroy, availability of "small" and "large" sizes distinguished by a wide nomenclature of geometric dimensions, the resistance moments and the moments of inertia of structures make it possible to design cost-effectively the retaining wall structures with a minimal metal consumption. When developing the range of steel pipe sheet piles of Trest Zapsibgidrostroy, it was taken as a basis, that the economic efficiency of the construction made of welded pipe sheet piles is also determined by the labor costs of its manufacturing.
The range of steel pipe sheet piles of Trest Zapsibgidrostroy is developed for provision of the design organizations with information about the possibilities of the plants of Trest Zapsibgidrostroy to produce steel pipe sheet piles with a wide range of geometric and physical-mechanical properties, as well as to inform designers about the possibility to choose among a large number of the designs of welded pipe sheet piles such piles that would ensure the most cost-effective solutions for retaining walls in relation to metal consumption and labor costs.
Production processes used for welded pipe sheet piles by Trest Zapsibgidrostroy make it possible to produce steel pipe sheet piles not only from the pipes of the RF range but also from the rolled pipes with a diameter of up to 3,000 mm, with the moment resistance up to 150.0 th. cm³ / m and the
