Poor quality 15crmo alloy steel pipe surface prone to scab and crack. High quality 15crmo alloy steel pipe composition uniformity, cold shearing machine tonnage high, cutting head face smooth and tidy, and poor quality material because of poor material, cutting the end of the face will often have the phenomenon of meat, that is uneven, and no metallic luster. Low-quality 15crmo allo y steel pipe prone to folding. Folding is a variety of lines formed on the surface of a 15crmo alloy steel tube, which often runs through the longitudinal of the product. Folding products will crack after bending, the strength of 15crmo alloy steel pipe greatly reduced. The appearance of inferior 15crmo alloy steel tube often has pock phenomenon. The pock is due to the irregularity of the surface irregularities of the 15crmo alloy steel pipe caused by the abrasion of the grooves.

ERW; outer diameter:21.3-660mm thickness:6-25mm LSAW; outer diameter:325-1524mm thickness:6-50mm SSAW: outer diameter:219-3200mm thickness:5-25mm ASTM A334 Grade 9 specification covers several grades of minimum wall-thickness, seamless and welded, carbon and alloy- steel tubes intended for use at low temperatures. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse affect on low-temperature impact properties.
