Q:How big is the seamless steel tube of DN50?
Domestic steel pipe diameter is generally divided into A series and B series, DN50 pipe diameter of 60mm and 57mm respectively, the wall thickness should be based on your design pressure, temperature, pipe material to calculate.
Q:What is the theoretical weight per square meter of the steel pipe diameter of the outer frame and the thickness of the tube wall 3mm 48mm?
Formula: outside diameter - wall thickness * wall thickness *0.02466=, weight per meter! : 48-3*3*0.02466=3.3291
Q:What is the buckling type thin-wall steel pipe? What is a tight set of thin-walled steel tubes? What's the difference between the two?
The nut body and the junction box are connected at one end by adopting metric fine tooth thread, and the pipe is connected with the pipe, and one end is the same as the straight pipe joint (direct). Withhold the box joint points inside and outside teeth two. The diameter of straight pipe joint is divided into 16mm, 20mm, 25mm, 32mm, 40mm, 50mm.
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:Is it good to buy a simple wardrobe or a steel pipe?
Therefore, the simple solid wood wardrobe and steel pipe wardrobe is good or bad, according to personal preferences to set, and that environmental protection seems to have grades, easy to crack
Q:What's the difference between the fastener type steel pipe scaffold, the floor type steel pipe scaffold and the overhanging type steel pipe scaffold?
Butt fastener: used for connecting two steel pipe joints.The base and the pad: is set up in the bottom of the pedestal pole, pay attention to the distinction between base and the base plate, usually with steel plate and welded steel pipe, base usually put on a backing plate, and the plate can be wood can also be plate.The foot board (see the diagram below), safety net (no explanation, this is very simple).
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;
Q:Where is a steel pipe casing usually used?
Classification of casing: rigid casing, flexible waterproof sleeve, steel pipe sleeve and iron sheet bushing, etc..
Q:45 and 316 which steel tubes are of high hardness?
316 stainless steel by adding Mo element, the corrosion resistance, and high temperature strength has greatly improved, high temperature can reach 1200-1300 degrees, can be used in severe conditions. 316F stainless steel is easy to cut stainless steel with high sulfur content. Good corrosion resistance, easy processing, good smoothness, suitable for axial parts.
Q:Why seamless steel pipe called seamless steel pipe?
Seamless steel pipe is a hollow section, without the joint round, square, rectangular steel. Seamless steel tubes are made of ingots or billets made by piercing and are then made by hot rolling, cold rolling or cold casting. Seamless steel pipe with a hollow section, as pipe conveying fluid, compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, bike frame and construction using steel scaffolding.
