Russian-standard pipe caps are a common fitting for closing the ends of Russian-standard pipeline systems. They are manufactured in accordance with the GOST 17379-2001 standard for steel butt-welding pipe fittings and are used in conjunction with Russian-standard pipeline and flange systems such as GOST 17378 and GOST 17376. The products are used to close end ports of pipelines, reserve standby pipe openings, and isolate the flow of media in pipelines, reducing impurity accumulation, media leakage, and pipeline corrosion, and helping to maintain stable pressure in the pipeline system. Specifications adopt the Russian-standard DN nominal diameter system, covering DN15-DN1200, with wall thickness grades Sch10-Sch160 and pressure ratings PN10 to PN100. In terms of materials, carbon steel is mainly ST20, 09G2S low-temperature steel, and 16Mn; stainless steel is mainly 12X18H10T, 08X18H10, and 316L; alloy steel can be adapted to special working conditions such as extreme cold and high pressure. Production processes include three types: integral hot-pressed seamless forming, steel plate rolled and welded forming, and forged precision-machined forming. We supply to customers such as engineering general contractors in Russian-speaking regions, EPC contractors, oil and gas energy developers, and cross-border B2B traders, and can confirm specific specifications, materials, and delivery arrangements according to project requirements.
