Reasons and advantages of steel welding for large-diameter steel pipes1. The use of large-caliber stainless steel can be divided into oil well pipes (casings, oil pipes, and drill pipes, etc.), line pipes, boiler pipes, mechanical structure pipes, hydraulic prop pipes, gas cylinder pipes, geological
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
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

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
