Pre-treatment and use of straight seam steel pipePre-treatment of straight seam steel pipe:Non-destructive inspection of the inside of the weld. Because the pipeline belongs to the extra-large steel pipe in the water supply project, especially the steel pipe with a thickness of t=30mm is used as a p
How to solve the deformation problem of spiral seam submerged arc welded steel pipeThe spiral seam submerged arc welded steel pipe is drilled in rotation and begins to enter the soft formation. Under the action of the tri-cone, the drill first produces elastic shear deformation of the stratum and th
Development status and prospects of domestic and foreign oil and gas pipelinesAn important driving factor for the development of oil and gas pipelines is the imbalance in the production and demand of oil and gas resources in various regions. Since the development of the oil and gas industry, most co
Overview:ASTM A234 is the standard specification for pipe fittings of wrought carbon steel and alloy steel for moderate and high-temperature service. The Cr-Mo low alloy steel pipe fittings has been separately listed on our website. Carbon steel pipe fittings manufactured to ASMT A234 are usually fu
ASTM A192 boiler tubes are made of grade 192 stainless steel that has undergone numerous test sample hardness tests, flattening tests, flaring tests, flange tests and hydraulic tests. We basically manufacture these ASTM A192 boiler tubes according to the seamless cold drawn process to maintain their
As oil and natural gas resources are often located in remote areas and harsh environments, greater pressure pipelines transporting, complex and corrosive media, and pipeline welding assembly ring general in the wild, which not only requires pipeline steel with high strength, and requirements should
ASTM A210 seamless medium carbon steel pipe is applied for boiler pipe and boiler flue pipe with the minimum thickness, including safety end, vault, supporting pipe and super heater pipe.SpecificationHot rolledOutside Diameter , mmTolerance, %OD≤101.6, WT≤2.4+40/-0OD≤101.6, 2.4＜WT≤3.8+35/-0OD≤101.6,
Also known as spiral or helix spiral steel pipe, is a low-carbon steel or low-alloy structural steel strip at a certain helix angle (called molding angle) rolled into a tube, and the tube is made of welded joints It can be produced with a narrow strip of large diameter pipe. Classes of spiral steel
Threeway Steel is in the conventional austenitic stainless steel, based on strict control of impurities on components made further refined and improved composite - Diverse developed from strengthening means, is dedicated to a new supercritical unit boiler austenitic stainless steel . In this steel,
EN 10025 includes a series of European standards for structural steel products, delivery condition is specified as hot rolled. For example, hot rolled steel coils, hot rolled steel section. EN 10025 standard (6 parts) covers a wide range of structural steel product.Tolerance Chart of En 10025 Cold D
