Detailed Introduction

Main standards: DIN2391-94/C DIN1630 EN10305 DIN2445 ASTM A179 JIS G354 SAE J524
Main materials: ST35/E235 ST37.4 ST45/E255 ST52/E355
Delivery status: NBK(+N) BK(+C) GBK(+A) BKW(+LC) BKS(+SR)
Process Introduction: High quality carbon steel, precision drawing, non oxidizing bright treatment (NBK state), non-destructive testing, special equipment brushing and high-pressure flushing of the inner wall of the steel pipe, rust proof oil treatment on the steel pipe, and dust prevention treatment on both ends of the cover.
Main features: high precision, good smoothness, no oxide layer on the inner and outer walls of the steel pipe after heat treatment, good cleanliness of the inner wall, and the steel pipe can withstand high pressure without leakage. Cold bending does not deform, expanding and flattening without cracks can perform various complex deformations and mechanical processing treatments
