Properties of the Ceramic-lined Steel Composite Pipes

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

What is AISI steel?

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?

What is the meaning of ASTM standard?

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?

Difference between ERW, DOM and Seamless Tube

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
