We can apply any type of Bevel to any degree required. Beveling can applied to the face of any size or diameter of pipe. Other angles and special forms such as J-Bevels can also be produced on the ends of pipe or tube using automatic beveling machines. Why bevel a pipe? A standard pipe bevel … Continue reading Pipe Beveling
The seamless steel pipe manufacturing process starts with a solid, round steel billet.
Steel pipes are long, hollow tubes that are used for a variety of purposes. They are produced by two distinct methods which result in either a welded or seamless pipe. In both methods, raw steel is first cast into a more workable starting form. It is then made into a pipe by stretching the steel … Continue reading Steel pipe
Ceramic (Corundum: a-Al2O3) lined abrasion resistant straight pipe and fittings are lined with highly abrasion resistant ceramic by SHS -------Self-propagating High-temperature Synthetic process. Mechanical Propertie: Hoop Strength: Hoop strength is the resistance against radial pressure. The strength of the ceramic -lined steel composite pipe is 300 to 500MPa. Compression-Shear Strength: Compression-shear strength is the bonding … Continue reading Properties of the Ceramic-lined Steel Composite Pipes
ASTM A213 Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes
The US designations for steels are those of the American Iron and Steel Institute (AISI) and the Society of Automotive Engineers (SAE).
SAE International, as a standards organization, maintains several alloy numbering systems, one of which, for steel grades, is the SAE steel grades system. In the 1930s and 1940s the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels. Welcome to Sunny Steel Enterprise … Continue reading What is AISI steel?
ASTM International, known until 2001 as the American Society for Testing and Materials (ASTM), is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services. ASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of … Continue reading What is the meaning of ASTM standard?
Seamless Pipe. Tubular product made without a welded seam, manufactured in a hot-forming process using an extrusion or drawing process that can be followed by cold sizing or cold finishing to produce the desired shape, dimensions and properties.
This month we take a hard look at the differences between ERW, DOM and Seamless Tube. ERW (Electric Resistance Welded) The nomenclature ERW refers to a specific type of welding process that involves both spot and seam welding. Seam welding is commonly used during the manufacturing of round, square and rectangular steel tubing. The steel … Continue reading Difference between ERW, DOM and Seamless Tube
