What is forged and rolled alloy steel?
Forged and Rolled Alloy Steel is not a single standard designation, but refers to alloy steel materials produced through forging or rolling processes. In industrial fields (especially in pipe fittings, your area of focus), this term is commonly used to describe the material condition of flanges, fittings, or valves. It emphasizes the production process and…

What is a valve?
A valve is a control component in fluid delivery systems. Its primary function is to change the cross-section of the flow path and the flow direction of the medium, with functions including flow diversion, shut-off, regulation, throttling, check, diversion, or overflow and pressure relief. Simply put, a valve is the “switch” and “regulator” of a…
What is a nickel alloy steel plate?
Nickel alloy steel plate refers to a high-alloy steel plate material that takes nickel as the base element, with one or more alloying elements added — such as copper, chromium, molybdenum, iron, titanium, aluminum — and manufactured through smelting, rolling and other processes. It is not ordinary nickel-plated steel plate, but a plate made of…
What is a chromium-molybdenum alloy steel pipe?
Chromium-Molybdenum Alloy Steel Pipe, often abbreviated as Cr-Mo steel pipe or simply Cr-Mo steel, is a type of seamless steel pipe specifically designed for service in high-temperature, high-pressure, and hydrogen-corrosive environments. It is based on carbon steel, with the addition of two key alloying elements: chromium (Cr) and molybdenum (Mo). The combination of these elements…
How to take moisture-proof measures for pipe fittings?
The purpose of taking moisture-proof measures for pipe fittings is to prevent rust, corrosion or water stains on metal surfaces and ensure the fittings remain in good condition during storage, transportation and before use. The following are common and effective moisture-proof methods applicable to various steel pipe fittings, stainless steel pipe fittings, alloy pipe fittings,…
Welding Procedure Specification for Pressure Vessels
Welding Procedure for Pressure Vessels (also often referred to as Welding Procedure Specification, WPS, or Welding Operation Instruction) is a set of technical documents used to guide the welding production of pressure vessels. It serves as a critical basis for ensuring welding quality and safe, reliable operation of equipment. It must be formulated in accordance…
