* Application
Hot dip galvanized pipe is widely used in communications equipment, construction, machinery, coal, chemical industry, railway vehicles, automotive industry, roads, Bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery manufacturing industry.
Hot dip galvanized tube surface is plated layer or electric galvanized welded steel pipe. Galvanized steel pipe corrosion resistance can increase, prolong service life. Galvanized pipe USES is very wide, in addition to a general low pressure fluid such as water, gas, oil line pipe, also used as oil industry, especially the ocean oil field oil well pipe, oil pipe, chemical coking equipment of oil heater, the condensing, exchange of coal distillation wash oil cooler for tube, and trestle pile, mining tunnel supporting frame tube, etc.
*Production Process
Hot dip galvanized pipe is the molten metal and iron substrate reaction and produce alloy layer, so that the substrate and coating combination of both. Is hot dip galvanized steel pipes to pickling, in order to remove iron oxide on the surface of the steel tube after acid cleaning, by ammonium chloride or zinc chloride or ammonium chloride and zinc chloride mixed aqueous solution tank cleaning, and then sent to the hot dip plating tank. Hot dip galvanized with uniform coating, strong adhesion, long service life, etc. Galvanized pipe and hot galvanized pipe matrix molten solution of complex physical, chemical reaction, the formation of corrosion resistance of the structure compact zinc alloy layer. Pure zinc alloy layer and layer and steel substrate. So the corrosion resistant ability.

About Packaging.
1. by bundles, each bundle weight under 3 tons, for small outer diameter seamless steel pipe, each bundle with 4 - 8 steel strips.
2. after making by bundle, covered with Polyethylene waterproof cloth.
3. make black paints painting on each pipe, then make bundles
1. What is your minimum order quantity?
For steel plate;one piece is ok. For steel pipe;one ton is ok.
Too litter quantity,the cost relatively high added fregiht. Larger quantity, better price.
2.How long will it take to receive my order?
7 days for stock sizes, 20-25 days for new product
3.Which type of shipping do you usually choose?
Packaging
when each plate weight is under 1 ton, it will be in bundle with steel strips 2-4, when each plate weight is over 1ton, it will be piece by piece.
20 feet container contains dimension:Width under 2300mm, length under 6000mm
40 feet container contains dimension:Width under 2300mm, length under 12000mm
By bulk vessel:Freight charge is low by bulk cargo, and large heavy sizes can not be loaded into containers can shipping by bulk cargo
