Seamless pipes
Seamless pipes differ from electric resistance welded pipes by not having the connecting seam. Due to that seamless pipes have high durability and safety performance and they are usually used in sectors, where the human safety depends on durability of the material. Seamless pipes are manufactured from whole steel bars, in which during manufacturing process penetrating opening are formed. Manufactured according to standard: EN10220, DIN2448, GOST 8732, steel grade S235JRH, P235TR2, S355J2H, P355NH. Each pipe is tested under test pressure.
According to standard EN10220, DIN2448, GOST8732, steel grade S235JRH, S355J2H, P355NH.
