Q:Water, gas, steel pipes, thick steel wire means?
Thick steel wire pipe is the same wire pipe, but the wire pipe is thin tube, easy to damage, so with thick as the outer diameter can protect the wire tube, so called thick steel wire pipe.
Q:What type of steel pipe for security windows?
25 parties, 70 parties in general! Good point of about 90; 25/38 general 90, a good point of about 120! The model is usually 202. If 304 is used, it is usually multiplied by 2! Plastic steel window material is hard plastic! Inside a single glass lined steel prices have 75/90/120/150/ different brand price this is the price of the window! Aluminum alloy is generally 100/120/150/175/190 area, different prices different
Q:How can galvanized steel tubes be painted on the surface?
The market is commonly used in alkyd iron red primer, iron red epoxy primer are not suitable for galvanized parts, otherwise it is easy to fall off. It is important to point out that the saponification of the galvanized sheet with alcohol, acid and paint will result in the failure of the coating and the damage of the original zinc coating.
Q:Why can't stainless steel be put together with carbon steel tube?
Stainless steel can not be put together with carbon steel because of galvanic corrosion
Q:What is ND steel pipe?
ND steel 09CrCuSb steel is currently the most ideal "resistance to sulfuric acid dew point corrosion in steel (ND steel, ND steel, 09CrCuSb steel, 09CrCuSb steel), ND steel is widely used in the manufacture of economizer, served in the high sulfur content in flue gas of air preheater, evaporator and heat exchanger equipment for resist sulfur smoke gas dew point corrosion.
Q:Are metal spiral tubes the same as metal bellows?
Hello. The two are not the same. The difference lies in. The pitch of a spiral pipe is much larger than that of a bellows. The maximum material thickness of the spiral tube is much thicker than that of the bellow. The diameter of a spiral tube can be very large. But the bellows can't be too big in diameter.
Q:Is the steel frame on each floor supporting formwork (floor) called full scaffolding?
After the use of full scaffolding, more than 3.6 meters of interior wall decoration is no longer calculated decorative scaffolding, and the interior wall of the scaffolding is still in accordance with the provisions of the scaffolding.
Q:Is hot dipped plastic pipe steel?
The characteristics of hot dipped plastic pipe are:1., hot dipped plastic pipe superior anti-static performance: through the formula to add antistatic agent, so that its internal and external surface resistance value reached and exceeded the national industry standards.2., such as the use of plastic raw materials, add flame retardants. The flame retardant performance index conforms to the national standard, and the steel plastic composite structure has better flame retardance than the pure plastic pipe material, and is suitable for underground inflammable, explosive and other places.3. hot dip coating steel strong adhesion: steel surface after special treatment, curing, coating adhesion is greater than or equal to 30N/10mm.4., dense internal and external resin layer: coating thickness of more than 0.5 mm, no pinholes, with excellent corrosion resistance.The mechanical properties of plastic steel pipe superior 5. hot dip: can withstand the harsh conditions of use: coating steel has good toughness, high mechanical strength, impact bending and other foreign influence, has a strong bearing capacity, has better performance than other mine plastic pipes.6. hot dip steel corrosion and fouling, the fluid resistance is small: corrosion and fouling, especially suitable for the underground conveying high sulfur water and transport of calcium and magnesium plasma water, save the maintenance cost, service life is much higher than that of the other pipe, high economic benefit.7. self lubrication: smooth wall, no fouling, small transmission resistance, under the same conditions, can improve the transport capacity of 30%.8. convenient and reliable connectionThe utility model completely overcomes the defects of the difficult connection of the pure plastic mining materials, and can be connected with the underground steel pipe and the valve by using flanges, fast couplings, etc., and has strong interchangeability.
Q:How long is the seamless tube?
Welded pipe is generally 6912 meters fixed length, seamless pipe on the market in general non fixed foot, but usually more than 6 meters
Q:What does "HBB" glass steel pipe mean?
HBB glass fiber reinforced plastic cable protection tube is suitable for power, communication and communication cables laying protection pipes in all kinds of occasions. Especially in the traffic crossing through cable and cable bridge across the river, the use of the special environment, more fully reflects its simple construction, high strength performance, widely used in the construction of infrastructure, transportation, electricity, communications and other fields of Civil Aviation Airport
