Outer Diameter:17-219mm. HDG and GI diffrence - Carbon Steel Pipe and FittingsFeb 18, 2017 · HDG:Also called hot dip galvanized and hot-dip galvanized:is an effective way of metal corrosion, mainly for various sectors of the metal structure facilities. Is immersed steel rust after about 500 melted liquid zinc, steel member attached to the surface layer of zinc, which serve the purpose of preservation.
Hot-dip galvanizing (HDG), as referenced is the process of dipping fabricated steel into a kettle or vat of molten zinc. While the steel is in the kettle, the iron metallurgically reacts with the molten zinc to form a tightly-bonded alloy coating that provides superior corrosion protection to the steel. Hot Dip Galvanized Steel Pipes & Fittings China Supplier Hot-dip galvanized steel pipes are widely used in fire fighting, electric power and highways. Cold galvanized steel pipe. Cold galvanized steel pipe is electro-galvanized, and the amount of galvanization is very small, only 10-50g/m2, and its corrosion resistance is much worse than that of hot-dip galvanized steel pipe.

Hot-dip galvanizing is done in accordance with long-established specifications. There are three main specifications governing the coating thickness, adherence, and finish for hot-dip galvanized steel and a handful of supporting specifications referenced in these specifications cover design practices, repair and touch-up, and painting/powder coating over galvanizing. Mechanical Properties of Galvanized Steel PipeDec 12, 2016 · Date:2016-12-12 View(s):2264 Tag:steel pipe, galvanized steel pipe, hot dip galvanized steel pipe Mechanical properties of steel is to ensure the ultimate use of steel performance (mechanical properties) an important indicator, it depends on the chemical composition of steel and heat treatment system.
Pre-galvanized steel refers to steel which has been galvanized while in sheet/ coil form. Pre galvanized tubes are manufactured using these coils. Pre-galvanized tubes have a lower coating of zinc which makes them economical to use versus hot dipped galvanized tubes. However, one of the advantages of pre- galvanized tubes has over hot dip Pre galvanized steel pipe, Pre galvanized steel pipe Pre galvanized steel pipe from Tianjin Guangxin Iron And Steel Industrial & Trading Co., Ltd..

Reliance Metal Resource Co., Ltd., Experts in Manufacturing and Exporting steel pipe, square steel pipe and 320 more Products. A Verified CN Gold Supplier on . The Allied Advantage In-Line Galvanized Tubing Allied Hot-dipped products, like pre-galvanized products, generally have a higher lead content than Allied´s products which are galvanized with four-nine zinc, which is 99.99% pure. Gatorshield ® tubing (50 ksi yield strength) is significantly stronger (66%) gauge for gauge, yet is at least 31% lighter (OD/OD) than galvanized schedule 40 pipe.
Allied uses special high-grade quality zinc for its galvanizing operation. Our zinc is 99.99% pure and contains only a trace amount of lead. Hot-dipped galvanized pipe or pipe made from pre-galvanized steel coils normally use Prime Western grade zinc and other grades which contain a high level of lead, sometimes more than 1% by weight. Why are the galvanized steel pipes popular in greenhouse Dec 03, 2019 · Galvanized pipe for greenhouses frame is made by plain carbon steel with hot dipped zine coating, low cost than stainless steel.
