Why is ASTM A53 black steel pipe hot-dip galvanized?
Nov .07.2024
ASTM A53 black steel pipe also referred to as ASME SA53 pipe, is an excellent candidate for most processing. Featuring a semi-smooth surface coated with black lacquer. Black steel pipe is intended for mechanical and pressure application. Common applications include steam, water, air, and gas systems. ASTM A53 is the standards specification covers seamless and welded, black and hot-dipped galvanized nominal (average) wall pipe for coiling, bending, flanging and other special purposes and is suitable for welding.A53 bare steel pipe sizes are specified by two non-dimensional numbers. Nominal pipe size (NPS) or inside diameter (ID), and pipe schedule (SCH) referring to the wall thickness.
What is The Difference Between API 5L X42 And X52 Pipe?
Nov .05.2024
API 5L steel pipe standards are A25, A, B and "X" Grades such as X42, X46, X52, X56, X60, X65, X70, X80 and so on. The two-digit number following the "X" indicates the Minimum Yield Strength (in 000's psi) of pipe produced to this grade. Some people really confused about the X42 and X52, today here I will show you the comparison between them.
Standards for seamless steel pipes for high-pressure boiler tubes
Oct .31.2024
Seamless steel pipes for pressure vessels are also called high-pressure boiler tubes, which refer to seamless steel pipes used to manufacture various pressure vessels and boilers. The main function of seamless steel pipes for pressure vessels is to transport media to various equipment under high temperature and high pressure, such as power station boilers, chemical equipment, nuclear power plant equipment, etc. Therefore, the performance requirements of seamless steel pipes for pressure vessels are very high, and they must have good mechanical properties, high temperature resistance, corrosion resistance and reliable welding performance.
