ASTM A53 Seamless Steel Pipe. ASTM A 53 covers seamless and welded steel pipe with nominal wall thickness. The surface condition is usually black and hot-dipped galvanized. ASTM A 53 is produced mainly for pressure and mechanical applications, and is also used for transport of steam, water, gas line pipes. Design Considerations for Hot-dip Galvanizing:Cold Worked For steel sections with edges greater than 5/8" (16 mm) thick subject to tensile loads, cut using normal shop procedures. Edges of sections up to 5/8" (16 mm) thick may be cut by shearing. In critical applications, the steel should be hot-worked above 1200 F (650 C) in accordance with the steel manufacturer's recommendations.
As stated above, there are several different processes for galvanizing steel. Hot-Dip Galvanizing. The first and foremost method for galvanization is hot-dip galvanizing. The process is very similar to what the name suggests! In this method, steel or iron is dipped in a molten pool of zinc that maintains a temperature of around 860°F (460 °C).

Sep 07, 2016 · The hot-dip galvanizing of very thick steels (beyond 2-3 inches thick) presents process challenges to galvanizers such as a high zinc consumption rate and extra processing time. excessive immersion time (beyond an hour) is often the result of a cocoon effect which slows the heating of the steel MS ERW Black Steel Pipes Exporters MS ERW Hot Dipped SV Trade International- Manufacturer, exporter and supplier of Galvanized Corrugated Sheets, MS ERW Black Steel Pipes,MS ERW Hot Dipped Galvanized Steel Pipes (G.I Pipes) Square Hollow Sections Tubes, Preprinted Galvanized Steel Coil & Sheet, india MS ERW Black Steel Pipes Exporters MS ERW Hot Dipped SV Trade International- Manufacturer, exporter and supplier of Galvanized Corrugated Sheets, MS ERW Black Steel Pipes,MS ERW Hot Dipped Galvanized Steel Pipes (G.I Pipes) Square Hollow Sections Tubes, Preprinted Galvanized Steel Coil & Sheet, india
Apr 26, 2012 · The hot-dip galvanizing process takes place in a molten bath of zinc metal at a temperature of 840 ± 20°F. The coating process takes only a short time at this temperature, usually less than 5 minutes, so this limits the potential changes to the mechanical properties of the steel Pre Galvanized Steel Pipe, Hot Dipped Galvanized Steel Manufacting high-class Pre Galvanized Steel Pipe in India, Purchase Schedule 40 Hot Dipped Galvanized Steel tubing at factory price, contact Hot Dipped Galvanized Steel suppliers in Mumbai, Pune & Chennai - India for better price.
