Product Description:

1. Product Description:

Hot dip galvanized pipe is made of molten metal and iron substrate reaction to produce alloy layer, so that the substrate and the coating two. Hot dip galvanizing is first to pickling steel pipe, in order to remove iron oxide in the surface of steel, pickling, by ammonium chloride or zinc chloride aqueous solution or ammonium chloride and chloride zinc mixed aqueous solution groove cleaning is then fed into hot dip tank.

 

2. Product Characteristic:

Hot dip galvanized coating with uniform, strong adhesion, long service life, etc.. The complex physical and chemical reactions of the steel tube matrix and the molten bath have formed the structure of corrosion resistant. Alloy layer is integrated with the pure zinc layer and the steel tube. Therefore, its corrosion resistance.

Q:Is 30CrNiMo8 a kind of high alloy STEEL?
Yes,30CrNiMo8 is a high grade alloy steel. *These steels generally contain higher carbon concentration (0.25%). As they are hardenable their mechanical properties can be tailored to specific needs by suitable adjustment of the annealing temperature. Finished products can be hardened to have a high surface hardness in combination with a tough and ductile core. The mechanical properties increase with increasing carbon concentration. Cr and Ni add additional improvements in properties. The Mn grades are a little cheaper. V and Mo add improved temperature resistance. The grades Cxx are developed for less stringent quality requirements but are cheaper.
Q:Element Copper. How does copper make the world better? and also where do you find copper?
Copper is used in pipes and wires. It doesn't poison us like lead pipes and it's a better conductor than Aluminum wires. The best place to find copper is to rip out the pipes from an old abandoned building. Be sure to do this at night so nobody will catch you. If you're rich you can buy it at Home Depot or Lowes.
Q:What are the causes of the powder moisture in the ceramic filter?
The main speed of the ceramic filter is too fast.The vacuum of ceramic filter is not enough.The cleaning of ceramic filter has not met the requirement.The ceramic filter plate has a near life and a serious blockage.The selection of ceramic filter plate is different.Too much residual of ceramic scraper after discharge.
Q:Can wall bricks be pasted on the indoor glass fiber gridding cloth?
Yes. Glass fiber gridding cloth is used for roofing waterproofing and wall or board reinforcement such as gypsum and mosaics.
Q:Cleaning Aluminum Tanks?
If you do not get a direct answer from someone who knows the answer, maybe a boat builder conversant with all aspects of aluminium might be able to help. The one which springs to mind is Sea Otter Boats in Chesterfield, England - they are probably the experts in all things aluminium. They do have a web site.
Q:been working on copper pipes plumbing?
Sorry but teflon tape is the industry standard and works great when properly used. You may be over tightening or one of the fittings could be slightly out of round, either would cause your problem.
Q:Who knows about the grade C fireproof door materials?
I am happy to answer your questions. Wood or steel materials are usually used. The new national standard fire doors: According to the enacted GB12955-2008, the fire endurance of grade C fire doors is 0.5 hours and that of grade A and B are 1.5 hours and 1.0 hours respectively. I hope my answer can help you.
Q:Welding problems of two I-beam combinations
First, in the front, middle and back of the steel welding joint, fix the steel structure, and then according to the first in the middle and the two sides of the welding sequence welding (intermittent welding), if better control deformation, it is best to weld both sides at the same time
Q:Does anyone know where to sell parts for mechanical assembly on copper?
Which building materials market can you sell as long as you sell it by brass?
Q:Does asbestos gasket contain plasticizing agent?
No asbestos gasket is according to the requirements of various specific conditions to non asbestos sealing materials (using aramid fiber, high temperature resistant synthetic mineral fibers, rubber oil resistant materials, etc.) by the rolling method or stamping tools, sealing products of various shapes and shear. The non asbestos gasket is according to the international use of the new product, i.e. high temperature, high pressure resistance, corrosion resistance, and the product is.
