Detailed Introduction

The Russian-standard cross is a cross-node pipe fitting in GOST standard pressure piping systems, undertaking the functions of four-way medium diversion, convergence, and cross transfer. The product follows GOST 17380-2001 general technical conditions, and its size system matches Russian-standard steel pipes, with outer diameter, bevel, wall thickness reduction, and dimensional tolerances controlled according to Russian-standard specifications. The nominal diameter covers DN15-DN1400; small diameters adopt seamless hot-pressed forming, while large diameters adopt steel plate rolled and welded process. The pressure rating covers PN10-PN160, and materials include 20# carbon steel, 09G2S low-temperature steel, 12Х18Н10Т stainless steel, and 15CrMo alloy steel, among which the 09G2S material can adapt to -40℃ or even lower temperature environments, suitable for projects in Siberia and the permafrost regions of Central Asia. Before leaving the factory, hydrostatic testing and UT/RT non-destructive testing can be performed, and Russian-English bilingual material certificates can be provided. The product is used for new construction and old pipeline network renovation of oil and gas fields in the CIS, central heating, municipal gas and water supply and drainage, power stations, and chemical plants, meeting local supervision acceptance and customs clearance requirements.
