Galvanized rigid conduit (GRC) is galvanized steel tubing, with a tubing wall that is thick enough to allow it to be threaded. Its common applications are in commercial and industrial construction. [1] It is designed to protect wire and connectors. Intermediate metal conduit (IMC) is a steel tubing heavier than EMT but lighter than RMC. It may ...
In the recent past, HSS was commonly available in mild steel, such as A500 grade B. Today, HSS is commonly available in mild steel, A500 grade C. Other steel grades available for HSS are A847 (weathering steel), A1065 (large sections up to 50 inch sq made with SAW process), and recently approved A1085 (higher strength, tighter tolerances than ...
When steel pipes were introduced in 19th century, they initially were riveted, and later clamped with H-shaped bars (even though methods for making weldless steel tubes were known already in the 1870s [5]), until by the early 1930s these methods were replaced by welding, which is still widely used today.
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...

It is also weldable and can be used in structural applications, although ASTM A500 tube, which is available in the same NPS sizes, is sometime preferred. [ 2 ] This is a standard set by the standards organization ASTM International , a voluntary standards development organizations that sets technical standards for materials, products, systems ...
Galvanized surface with visible spangle. Galvanization (also spelled galvanisation) [1] is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are coated by submerging them in a bath of hot, molten zinc. [citation needed]
For thickly galvanized steel, aluminium and brass tubing. Widely used in electrical industry. Used in dairy industry. Broad melting range, can form fillets and bridge large gaps. 34: 16: 50: Ag 50 Cu 17 Zn 33: Ag–Cu–Zn 780/870 [41] – BAg-6b, BVAg-6b, Braze 502, Braze 503 (VTG grade for vacuum systems, with reduced volatile impurities ...
