Q:What are the uses of welded steel pipes?
The spiral submerged arc welded pipe (SY5036-83) for the delivery of pressurized fluid is made of hot rolled steel strips for tube billets, often spirally formed, welded by double submerged arc welding and used for the transmission of pressurized fluid. The steel pipe has strong pressure bearing ability and good welding performance. After a rigorous scientific examination and test, it can be used safely. The utility model has the advantages of large caliber of the steel pipe, high transmission efficiency, and investment in laying pipelines. Mainly used in the transportation of petroleum and natural gas pipelines.
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 does seamless steel tube mean? What are the main uses? What are the classifications?
The production process of seamless steel tube in general can be divided into two kinds of hot rolling and cold drawing, cold-rolled seamless steel pipe production process than hot-rolled billet to complex, first to three roller rolling and extrusion to sizing test, if the tube through the cutting machine cutting surface without crack growth response after cutting blank about one meter. Then enter the annealing process, annealing and pickling to use acid pickling liquid, should pay attention to the surface if there are a lot of bubbling, if there are a large number of bubbling pipe shows that the quality is not up to the standard. The appearance of cold rolling seamless steel tube shorter than hot-rolled seamless steel pipe, cold rolled seamless steel pipe wall thickness is generally higher than hot-rolled seamless steel pipe to be small, but the surface looks better than thick wall seamless steel pipe is more bright, rough surface is not too much, not too much burr diameter.
Q:Fastener type steel pipe scaffold external parts name
Foot board can be made of steel, wood, bamboo and other materials, each quality should not be greater than 30kg. Stamping steel foot board is a kind of commonly used foot board, usually with thick 2mm steel plate pressing, length 2-4m, width 250mm, the surface should be anti-skid measures. Wooden feet can use the thickness of not less than 50mm fir wood or pine production, length 3~4m, width of 200-250mm, both ends should be galvanized steel band two, in order to prevent the wooden foot end of the destruction.
Q:What does cathodic protection of steel tubes mean?
The corrosion of metals causes great economic losses directly or indirectly. Foreign statistics show that every year due to corrosion and scrap metal materials, equivalent to 20~40% of metal production, the world every year due to corrosion and loss of metal reached more than 1 tons.
Q:Is the PVC tube a plastic tube or a plastic tube?.
PVC is actually a vinyl polymerization substance, whose material is a non crystalline material. Polyvinyl chloride (Poly, Vinyl, Chloride, PVC), it is obviously impossible to steel, we often say that iron and steel, the steel must be the main component of iron, Fe, inorganic. And PVC, polyvinyl chloride, is an organic substance. Therefore, PVC can not be called steel, and PVC constitutes a large number of substances, not confined to the pipe type.
Q:Can stainless steel pipes spray black paint?
Can. The surface roughening with a thick gauze, do not use ordinary paint intensity difference. With resin paint, paint can be
Q:How can the immersed pipe pile put steel cage into the steel pipe? Which expert to answer?
Pile: refers to the use of hammer piling method and pile vibration method, steel casing with valve type pile tip or precast reinforced concrete pile boots into the soil, then pouring concrete (or first in the tube into the cage), while hammering or vibration of a pile side pull tube. The former is called hammer sinking pipe cast-in-place pile, and the latter is called vibrating sinking pipe cast-in-place pile.
Q:How many fasteners are there in a ton of steel tubes?
The fastener generally refers to the intermediate connecting parts connecting two members, in the construction project for external diameter of steel pipe scaffold with 48mm fixation, the fastener is divided into rectangular fastener (cross directional fastener fastener) rotary fastener (universal movable fastener fastener) (a direct docking fastener fastener fastener) etc..
Q:What steel pipes are buried for outdoor heating pipes? Seamless or welded tube? Are there any rules for specific countries? Can use the seamed tube?
The pipe material of heating pipe network should be designed according to the requirement. When the design is not specified, the following requirements shall be met:1 when the pipe diameter is less than or equal to 40mm, welded steel pipe shall be used.2 when the pipe diameter is 50 ~ 200mm, welded steel pipe or seamless steel pipe shall be used.3 when the pipe diameter is greater than 200mm, spiral welded steel pipe shall be used.
