Q:What material is RHS in the steel tube?
RHS is a rectangular hollow section steel. The RHS structure represents a rectangular hollow section steel.
Q:What is the production process of seamless steel tube?
Main production process of cold rolled (drawn) seamless steel tube:Blank preparation, pickling, lubrication, cold rolling (drawing), heat treatment, straightening, finishing and inspectionThe 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:Which is better, galvanized steel pipe or stainless steel?
Most of the use requirements are to maintain the original appearance of the building for a long time. In determining the type of stainless steel to be chosen, the main consideration is the aesthetic standards required, the corrosivity of the atmosphere in the area, and the cleaning system to be adopted. However, other applications increasingly seek only structural integrity or watertightness. For example, the roof and side walls of industrial buildings. In these applications, the construction cost of the owner may be more important than the aesthetic, the surface is not very clean can also. The use of 304 stainless steel in a dry indoor environment is quite effective.
Q:What quota is reserved for buried DN20 steel pipe?
It is an embedded sleeve control sub item, if the reserved hole, then there is no need to cover, special subject structure adjustment factor of the cost of the water supply and drainage engineering, water supply and drainage engineering he is buried under the charge.
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?
It is made up of steel pipe, fastener, base, foot board, safety net and so onSteel pipe rod: generally there are two kinds, an outer diameter 48mm, wall thickness 3.5mm; another kind of outer diameter 51mm, wall thickness 3mm; according to its location and function is different, can be divided into vertical pole, horizontal rod, sweeping rod, etc..Fasteners: fastener is the connection between the steel tube and steel tube, which has three forms, namely the right angle fastener, rotating fastener, butt joint fastener: rectangular fastener for connecting the two vertical pipes, it depends on the friction between the fastener and the steel pipe to transfer load. Swivel fastener: used for connecting two steel tubes intersecting at any angle.
Q:What quota should be installed for heating seamless steel pipe?
Should be in low carbon steel welding installation set industrial pipeline engineering quota, material to input the name and type of seamless steel pipe specifications and price; according to the description of the contents of related items can be set.
Q:Is the steel frame on each floor supporting formwork (floor) called full scaffolding?
The use of scaffold as its height, when the ceiling height below 3.6M, no matter what the ceiling decoration, decorative scaffolding are calculated
Q:Are galvanized steel tubes the same as degaussing steel tubes?
Degaussing steel tubeThe degaussing method specifies the following demagnetization in the established process document
Q:Who knows what is the difference between double submerged arc welded pipe and longitudinal submerged arc welding?
The straight seam welding is relative to the spiral welding and the T-shaped welding, and so on.
Q:What does "steel pipe SC" mean?
SC is an ordinary welded pipe, equal to water professional DN, SC is welded steel pipe concealed, general pipe wall is relatively thick, S represents pipe material, C represents laying mode, TC stands for wire pipe concealed, pipe wall is thinner.
