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
A179 scopeASTM A179/A179M, ASME SA179/SA179M is the standard applicable to Seamless cold drawn low carbon steel heat exchanger and condenser tubes, Those Standard require minimum-wall thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat tran
Overview of inconel productsA nickel-chromium alloy with good oxidation resistance at higher temperatures. With good resistance in carburizing and chloride containing environments. Our inconel is non-magnetic, has excellent mechanical properties and a combination of high strength and good workabilit
What is API 5CT?API 5CT is standard technical specifications for steel casing and tubing pipes used for oil wells in petroleum and natural gas industries.Besides casing and tubing, it also includes pup joints, coupling stock, coupling material, and accessory materials, and establishes requirements f
Inconel alloys are ideal for extreme pressure and temperature applications. They’re right for situations where steel and aluminum may fail because of thermal creep. When heated, Inconel alloys form a thick yet stable oxide layer, which protects surfaces from increased attack. When alloyed with other
What is Pipe?The pipe is a pressure-tight circular hollow section that used in piping systems to transport gases or fluids.Pipes are used in all kinds of process fluids and services. Tubes are generally used for heat transfer applications such as heat tracing lines, heat exchange, and fired heater a
Seamless surface cracks, opening wide outside off who called the opening is narrow, are known as fine as hair hairline. This deficiency is mainly caused by genetic tube surface cracks, but also affect the rate of qualified products mainly seamless. Seamless billet surface cracks causes, with the pro
ASTM A252 is pipe piling material standard that has been widely used in constructions and structural buildings.This specification covers nominal thickness of the wall steel pipe piles of cylindrical shape and applies to pipe piles in which the steel cylinder acts as a permanent load-carrying member,
