API 5L Seamless and welded Line Pipe
Friday, 15 December 2017
API 5L also requires a monogram license for Manufacturer, and it maintains the Composite Index of approved Manufacturer. This means that, at the request of a potential manufacturer, API will send auditors to the mill to ensure that they have the capability to meet the requirements of the standard. This would be similar to a

ASTM A519 / A519M Seamless Steel Mechanical Tubing
Tuesday, 12 December 2017
ASTM A519 / A519M This specification covers for several grades of carbon and alloy steel mechanical tubing, either hot-finished or cold-finished. The steel used in the mechanical tubing may be cast in ingots or may be strand cast. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required. The

what is the forming technology of seamless square tube and its applications?
Wednesday, 29 November 2017
Wall thickness of seamless steel pipe is relatively thick, relatively small diameter thick. But the diameter is restricted, and its applications are limited, and production costs, especially for large diameter seamless steel pipe production costs are relatively high. There are mainly three kinds of forming technology of seamless square tube: hot-rolled, cold-drawn and welded. For
