Q:What does "SC50" steel pipe mean in civil engineering?
Welded steel pipe refers to the use of steel or steel plate bending deformation into a round, square and other shapes after welding into the surface of the joint of the steel pipe. The blank used in welded steel pipe is steel or strip steel.
Q:What place must use galvanized steel pipe to make lighting line?
Galvanized steel pipe with hot-dip galvanizing or galvanized coating on it. Galvanizing can increase the corrosion resistance and prolong the service life of the steel pipe. The use of galvanized pipe is very wide, except for water, gas, oil and other general low pressure fluid pipeline, is used in petroleum industry especially offshore oil well pipe and oil pipe, chemical coking equipment oil heater, cooler, oil pipe exchanger for coal distillation, and support piles, Zhanqiao mine tunnel the tubes.
Q:Heating system DN40 and DN32 welded steel pipe how to connect?
As for the flange connection: low pressure pipeline is generally not used in this way, can be divided into threaded flanges and flange welding flange, and the flange connecting pipes of different diameters, only the welded flange to diameter, said in a low pressure pipeline which has low pressure pipe connection make an unnecessary move, this is not much, but there are also people with non the standard flange for connecting different pipe diameter, which is not consistent with the technical specification!
Q:Is steel pipe made of profiles?
Large steel: large steel, I-beam, channel steel, angle steel and flat steel are hot rolled, round bar, Fang Gang, six angle iron in addition to hot rolling, there are forging, cold drawn and so on.
Q:What is hot rolled steel pipe? What is a cold drawn steel tube?
General use seamless steel tube: is with 10, 20, 30, 35, 45# and other high-quality carbon steel, 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steel hot-rolled or cold rolled. Seamless tubes made of low carbon steel, such as 10, 20, are mainly used for fluid delivery pipelines. 45. Seamless tubes made of medium carbon steel such as 40Cr, used for the manufacture of mechanical parts, such as parts of automobiles and tractors. General use of seamless steel pipe to ensure the strength and flattening test. Hot rolled steel tubes are delivered in hot rolling or heat treated conditions. Cold rolled in heat treated state.
Q:Are steel tubes and round steel in weight or length when purchased?
A large amount of words is calculated by weight, less is usually calculated. According to the length between the length and quality of a material is usually a scaling. Steel belongs to the section, with the length of valuation, according to the classification of wall thickness and diameter; round steel belongs to building materials, mostly for the amount of weighing per ton of valuation, a small amount of more than according to the length multiplied by the conversion ratio of weight to that theory. But the latter is the valuation of tons of steel products between the uneven thickness, with uniform proportion will produce larger price difference, so the general price of different manufacturers are not the same, mostly depends on the quality, to a certain extent is to balance the diameter difference.
Q:Can galvanized steel tubes simmer?
Galvanized pipe bending is one of the elbow, the surface of the pipe is coated with a layer of zinc material to improve the corrosion resistance of the elbow. Galvanized pipe bending hot galvanized and galvanized two kinds, hot galvanized, zinc coating thickness, zinc plating cost is low, the surface is not very smooth. Galvanized pipe bending cold tube, hot tube, the former has been banned, and the latter is also advocated by the state for the time being.
Q:What's the difference between straight steel pipe and seamless steel pipe?
Seamless steel pipe and welded pipe are separated because of different production process. Seamless steel tubes include hot rolling, cold rolling, cold drawing, and other rare, such as cold extrusion.
Q:What materials are used in scaffolding pipes?
Safety net with dense green net, safety net of flame retardant standards GB, and safety net of flame retardant performance detection for lighter lit mesh 12 seconds after leaving the fire, flame retardant, continued burning of not more than 4S. The application of 9MM safety net rope, rope, nylon rope woven, each network should be able to withstand the impact of the national standard 1.6KN test.
Q:Galvanized steel pipe in addition to good rust resistance, what are the advantages?
Because the zinc has been plated outside the steel tube, the time for oiling or painting outside is omitted, and the construction is more convenient;
All these steel pipes are suitable for the industries of oil, natural gas,ship building,chemical, environmental protection,boiler, water conservancy, electrical industry,steel structure, building and other related fields.Our company following the principle that ‘customer supemacy, business integrity’We will do our best to supply best products and service to our customers. We expect mutual benefit.
