Q:What does "SC50" steel pipe mean in civil engineering?
SC50: laying on welded steel tubes of diameter 50mm. SC is usually used in electrical installation drawings.
Q:Difference between seamless steel pipe and welded pipe
Seamless steel tubes are made of high quality carbon or alloy steel. They are hot-rolled and cold-rolled (drawn).The welded pipe is rolled into the steel tubular to sew or spiral seam welded in the manufacturing method, and is divided into low pressure fluid delivery with welded steel pipe, spiral welded steel pipe, welded steel pipe, welded pipe roll etc..
Q:Will the steel tube dance?
The steel tube dance tube has a rotating steel tube and a fixed steel tube, so that different types of steel pipe can be chosen according to the type of pipe dance performed by the dancer.
Q:What are the lengths of scaffold steel tubes?
Scaffold tubes are our name for materials used to build scaffolding, because most scaffolding uses tubular bamboo or steel tubing. Bamboo and other bamboo is for a long time in the use of the scaffolding tube, but due to lack of safety and durability, now only in rural and urban area construction is lagging behind some of the home building small building has been used. The modernization construction, the most commonly used type of scaffolding pipe is steel pipe, the scaffolding should not only meet the demand of workers, but also to meet the characteristics of scaffolding firm and durable, so tough hard steel is the best choice. The selected steel pipe generally requires smooth surface, no cracks, no bending, no rust, and meet the relevant national standards.
Q:What is the weight of hot galvanized steel tubes? DN150 4mm wall thickness
GB/T3091-2008: DN150 welded steel pipe, wall thickness of 6mm, the theory of the weight of welded steel pipe 24.02kg/m, galvanized steel pipe should be multiplied by the weight coefficient after galvanizing, C, DN150, wall thickness of 6mm, C=1.02, DN150, theoretical weight and wall thickness of 6mm galvanized steel 1.02*24.02= 24.5kg/m.
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 does the diameter of a steel pipe project mean?
Nominal surface meaning can be understood as a public address. It's as if everyone agreed to call something as a "devil", and he was the devil.Don't be confused by the numbers behind the nominal diameter. For example, DN50, this 50 is really close to the outer diameter or inside diameter of the steel tube, but DN50 is only a general model of the caliber of the national standard.
Q:Are steel tubes and round steel in weight or length when purchased?
The price must be measured by weight, and the length, volume and other specifications should be entered
Q:What quota should be installed for heating seamless steel pipe?
Installation quota of seamless steel pipe project, if it is indoor engineering, sets of welded steel pipe, the price adjustment can
Q:How many fasteners are there in a ton of steel tubes?
In general, 180-200 fasteners per ton of steel pipe.
