Q:What kinds of steel pipe are divided into?
According to the weld shape can be divided into longitudinal welded pipe and spiral welded pipeStraight welded pipe: the production process is simple, high production efficiency, low cost, rapid developmentSpiral welded pipe: strength ratio of longitudinal welded pipe is high, with a narrow billet production of large diameter pipe, also can use the blank production of the width of the same diameter of different pipe. But with the same length of straight pipe, weld length of 30~100%, and the production rate is low. Therefore, the smaller diameter pipe most used straight large diameter pipe welding, mostly using spiral welding.Dividedagain general welded pipe, galvanized pipe, blowing pipe, wire tube, pipe metric, roller tube, deep well pump, tube for automobile, transformer tube, welding, welding of thin-walled tube shaped tube and spiral welded pipe.General general pipe: pipe used for conveying the low-pressure fluid. Q195A, Q215A and Q235A made of steel. Also can be used for easy welding of mild steel. The other pipe to conduct water pressure, bending and flattening test, have certain requirements on the surface quality, usually the delivery length is 4-10m, often requires a fixed length (or size) of delivery. The specifications of welded pipe with nominal diameter (mm or inches) nominal diameter and different pipe wall thickness, according to the provisions of general steel and thicker steel two, steel pipe end is divided according to form of threaded and non threaded two.
Q:What are the specific differences between flexible pipes and rigid pipes?
The rigid waterproof sleeve is used in the wall of the building which does not need to bear the vibration and expansion deformation of the pipe, and the wall thickness is 200mm in general;Flexible waterproof sleeve is mainly applicable to the wall of buildings with seismic requirements, pipeline vibration and expansion deformation, and strict waterproof requirements, and the wall thickness is 300mm
Q:Can the KBG25 steel tube hold 4 six types of cables?
Over five types of cables, the outer cross section is about 24 square millimeters, over six types of network cable for the outer cross section of about 35 square millimeters, so 35*4/490=28.57%, far more than 20%. Therefore, according to the norm, only 3 super six categories can be worn. If the distance is short and the joint is not enough, it can be laid like this, but it does not conform to the construction standard
Q:What time what time for gas pipeline steel pipe PE pipe
PE pipe must be installed underground, the steel tube can be exposed, when not all PE pipe for pipe laying, overhead installation. But the steel tube is easy to rust, so it can be used where the basic use of PE pipe buried PE pipe.There are galvanized steel pipe and seamless steel pipe, galvanized pipe can only be used for low-pressure homes
Q:DN80 seamless steel tube, what is the standard thickness?
Generally speaking, the diameter of the pipe can be divided into outer diameter, inner diameter and nominal diameter. Tubes are made of seamless steel tubes. The outer diameter of the tubes is indicated by the letter D, followed by additional outer diameter dimensions and wall thicknesses such as seamless steel tubes with an outer diameter of 108.
Q:Is there any difference between thermal expansion seamless steel pipe and seamless steel pipe?
Differ,Thermal expansion seamless steel tube is what we often call "thermal expansion tube", the density is relatively low, but a strong contraction of the steel pipe, (seamless steel pipe) can be referred to as "heat expansion.". A finishing rolling process for pipe rolling by using oblique rolling or drawing method to enlarge pipe diameter. In a relatively short period of time, the outer diameter of the steel pipe becomes larger, and the seamless tube with nonstandard and special type can be produced, and the cost is lower and the production efficiency is high, which is the development trend of the international rolling tube field at present.
Q:What are low-pressure carbon steel tubes?
Any of various steels that contain less than 2.11% of the mass of carbon but contain no alloying elements. Sometimes referred to as plain carbon steel or carbon steel.Carbon steel, in addition to carbon, usually contains a small amount of silicon, manganese, sulfur and phosphorus.1) according to the use of carbon steel can be divided into carbon structural steel, carbon tool steel and easy to cut structural steel three categories, carbon structural steel is divided into engineering construction steel and machine manufacturing structural steel two kinds;(2) by refining methods can be divided into open hearth steel, converter steel;(3) according to deoxidization methods, they can be divided into boiling steel (F), killed steel (Z), semi killed steel (b) and special killed steel (TZ);(4) according to the carbon content of the steel can be divided into low carbon steel (WC = 0.25%), carbon steel (WC0.25% - 0.6%) and high carbon steel (WC>0.6%);(5) according to the quality of steel, carbon steel can be divided into ordinary carbon steel (phosphorus, sulfur, higher), high quality carbon steel (low phosphorus and sulfur) and high quality steel (lower phosphorus and sulfur) and super quality steel.Description: the carbon content in general carbon steel is higher, the hardness is higher, the strength is higher, but the plasticity is lower.
Q:The plastic pipe and steel pipe difference
Plastic pipe and plastic inner coating, and coated inside and outside. (of course, some are epoxy coated, and some are PE).The plastic tube is one kind of steel pipe, steel plastic pipe has many types, including plastic, plastic, and plastic coated, and epoxy, which are known are steel tubes.
Q:What is the outer diameter of the steel tube?
The outer diameter refers to the maximum diameter including the thickness of the steel tube, the inner diameter is the length of the hollow part inside, and the outer diameter minus the inside diameter is the thickness of the steel pipe
Q:What is the difference between hot dip galvanized steel pipe and galvanized steel pipe?
1, the process is different, one is chemical treatment, one is physical treatment; hot-dip galvanized coating is reliable, not easy to fall off2, hot-dip galvanized coating thickness, so strong corrosion resistance. And zinc plating (electroplating) coating evenly, surface quality is better, coating thickness is generally between a few microns to more than ten microns.3 hot galvanizing is a chemical process, which belongs to electrochemical reaction. Zinc plating is a physical treatment, just brush a layer of zinc on the surface, there is no galvanizing inside, so the zinc layer is easy to fall off. Hot-dip galvanizing is used in building construction.4 、 hot galvanized pipe is to make molten metal and iron matrix reaction and produce alloy layer, so that the substrate and coating two combination.
