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:what's the varieties of fire-proof sealing material?
Fire blocking material currently on the market include: fire stopping board, foam blocking material, flame resisting module, fire-resisting sealant, flexible organic caulking, WXY-II and fire retardant bag, etc. fire-proof sealing material is widely used in building construction and can ensure high-temperature flame and smoke from fires not spread to another fire compartment, different buildings generally use different sealing methods. Pipeline is generaly sealed by pouring concrete board or mortar.
Q:What's the fireproof specification for constrcution external wall thermal insulation materials?
incombustible material: Class A1 (homogenous): such as YT inorganic active insulation material for wall thermal, foam glass, rock(ORE) wool, glass wool, insulation board of aerogel,expanded perlite series, expaned glazed hollow bead, foam insulation boards, ETC. Class A2 (non-homogeneous composite): such as phenolic foam, gelatine powder polyphenyl granule thermal insulation material, inorganic coating materials and other nonflammable material. phenolic foam insulation board, urea resin foam and board, high flame-retardant polyurethane rigid foam and board, high flame retardant polystyrene cystosepiment, gelatine powder polyphenyl granule heat insulating slurry and other combustible materials. Requirements for combustion levels of common antiflaming EPS, common inflaming retarding XPS, common antiflaming rigid PU foam board: Class A is incombustible material (product); B1 nonflammable material (product); B2 combustible material (product); B3 combustible material (product).
Q:refractory bricks of fireclay
According to the preparation process, it can be divided into bricks, high alumina brick, magnesia brickand so on, such as refractory clay brick, and ordinary brick; according to the shape and size, it can be divided into standard brick and silica brick, it can withstand all kinds of physical and chemical changes and mechanical action at high temperature; silica brick can be used as high-temperature building materials and structural material to build kiln and kinds of thermal equipments. Refractory material and fused brick with a certain shape and size are called refractory brick for short.
Q:What kind of foundry ingot refractory materials are there? Please be more detailed.
This question is a little bit extensive, because there are too much foundry ingot refractory materials.
Q:What refractories are resistant to fluorine gas?
It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
Q:If external insulation material is insulation putty, is it necessary to wrap external corners of mesh?
Before being paving, mesh shoule be scraped a leveling blamket with cracking resistant mortar on insulation layer. Then paste mesh, slightly press it with trowel, and scrape another cracking resistant mortar to make sure that mesh is outside of the cracking resistant mortar so that it is crack-resistant.
Q:How much is refractory spraying coatings?
Different brands and models have different prices. For example: Refractory temperature: 1580 ~ 1770 ℃ | Brand: Hengli | Product category: dedicated castable for biomass burning machine | Material: castable Price: 3000.00 refractory temperature: 1770 ~ 2000 ℃ | Brand: Great Wall | Category: unshaped refractory material | Material: corundum mullite Price: Refractory temperature: 1580 ~ 1770 ℃ | Brand: Guanghuayaoye | Product category: refractory material| Material: high alumina Price: 2500.00 The above prices obtained from the Internet are for reference only, and please pay attention to the purchasing price.
Q:Could you tell me the fire-resisting time of class B fire proof door?
Could you tell me the fire-resisting time of class B fire proof door?
Q:is general aluminum sheet fire-proof?
nonfireproof
Q:The advantages and disadvantages of waterproof aluminum film and aluminum foil
There are no EPE in aluminium film, so that it can not preserve the heat.The aluminum in the aluminum foil is thin so that its waterproof is weak.
