ASTM A106 Gr.B Ship Building Steel Pipe. The Seamless Steel Pipe for ships refers to the special seamless Steel Pipe in the shipbuilding process, a kind of steel pipe for ships, which relates to the technical field of shipbuilding; , anti-corrosion inner coating, waterproof inner coating, pipeline; the inner side of the steel pipe wall is provided with an anti-corrosion inner coating, the inner side of the anti-corrosion inner coating is provided with a waterproof inner coating, and the inner side of the waterproof inner coating is provided with a pipe The outer side of the steel pipe wall is provided with an anti-corrosion coating, the outer side of the anti-corrosion coating is provided with a waterproof outer coating, and the outer side of the waterproof outer coating is provided with an anti-impact layer. It can effectively avoid the loss caused by long-term water ingress and corrosion, and prolong the service life of the steel pipe. Steel pipes for ships refer to Seamless Steel Pipes for pressure-resistant piping systems of ships and boilers and superheaters. This type of steel pipe is made of High-Quality Carbon Structural Steel. The phosphorus and sulfur impurities in the steel are lower, and the comprehensive mechanical properties are better.

1. The main production process of hot-rolled seamless steel pipe (main inspection process):
Tube blank preparation and inspection→tube blank heating→piercing→tube rolling→steel reheating→fixed (reduced) diameter→heat treatment △→finished tube straightening→finishing→inspection (non-destructive, physical and chemical, Taiwan inspection)→warehousing
2. The main production process of cold-rolled (drawn) seamless steel pipes:
Billet preparation→pickling lubrication→cold rolling (drawing)→heat treatment→straightening→finishing→inspection
Our products aye widely used in water engineering,petrochemical industry,chemical industry,electric power industry,agricultural irrigation,urban construction.
Used for liquid conveying:water supply and drainage.For gas transport:gas,steam,liquefier petroleum gas.
For structural use:as pile pipe,as a bridge;Pipes for wharves,roads and building structures.
