Product Description:

1、Structure of  Conveying low pressure fluid seamless steel: 

Seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.

 

2、‍‍Main Features of  Conveying low pressure fluid seamless steel:

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

• Reasonable price

Q:Seamed steel pipe seamless steel pipe, carbon steel pipe, galvanized pipe, four how to distinguish between
Major use differentiation:1, seamed tube can withstand the maximum operating pressure is generally less than 20 kg, which is the most secure use. It is generally used in water, gas, compressed air and other low-pressure fluid;2 seamless tube can withstand ultra-high pressure, of course, its wall thickness will also increase, which needs to be designed according to pressure requirements. It is generally used in high-pressure oil pipes, boiler tubes and other high temperature and high pressure equipment. There are also seamless tubes for structural purposes, depending on the design requirements.3, there are some seamed steel pipe seamless treatment tube, it is the weld annealing treatment, eliminate the residual stress of the weld, the weld and base material, the pressure range of basic and seamless pipe is. May also consider the use of.4, of course, the market also has some use overall heating after drawing steel pipe joints or mandrel rolling seamless steel pipe, mainly in small size, only in the shape of this kind of pipe belongs to the seamless tube, it is not very good
Q:ASME seamless tube how to express, what is the form, I did not find on the ASME, thank God!
You can refer to the ASME B31.10, such as the requirements for the SA106GRB seamless steel tube outer diameter of 168.3 x 7.11, specifications can be marked as NPS6 SCH40 SMLS, the real mark should include pressure steel pipe factory name or trademark, and the material level, specifications, standards, wall number, batch number, pressure test (if any), NDE detection (if any)
Q:How much is the wall thickness standard of building 48?
Steel tube (Steel pipe) production technology development began in the bicycle manufacturing industry, the rise of the early nineteenth Century during the oil development, the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry of petroleum and natural gas drilling and transportation, will effectively promote the the yield and quality of varieties, the development of steel tube industry.
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 connections are there for concrete filled steel tubular column foundations?
The Liang Duan local widening joint is achieved by the continuous construction of longitudinal steel bars around the steel tube. At the beginning of the creation of additional stirrups should be widened longitudinal reinforced wrap, Liang Duan local widened joints of steel reinforced concrete beam and corbel overlapping transition zone can transmits beam internal force, bending steel bracket in both shear and participation. The node form is used in building engineering in Xiamen. The force transfer path of this joint is clear and reliable, with less welding on site and more convenient for construction. This kind of node passes shear stress through the bracket, and the stress is more concentrated.
Q:How to make the internal tooth of the steel pipe?
Compared with the ordinary light pipe, tube can effectively prevent the formation of steam film between the seal and the pipe wall, increase the light disturbance flow inside the tube, the tube wall temperature is more uniform, which can avoid the light pipe damage, and improve the heat transfer efficiency of boiler. The number of thread head of internal thread pipe is 4, 6 head and 8 head according to need. The main materials are 20G, SA210C, T2, T12, 12Cr1MoVG, 15CrMoG, T22, T23 and so on. China needs 2.5~3.0 tons per year of inner thread tube.
Q:Is there any difference between HFW steel pipe and ERW steel pipe?
Resistance welding, as the name suggests, resistance welding is a method of welding by welding electrode after exerting pressure on electrode and utilizing electric current through the contact surface of connector and adjacent zone. High frequency welding: high frequency current through the metal conductor, will produce two kinds of peculiar effects: skin and proximity effects, high frequency welding is the use of these two kinds of effects of steel pipe welding, the effects of the two is based on the high frequency welding metal.
Q:What's the difference between round and round tubes?
Round steel is solid and round tubes are hollow
Q:How to perform nondestructive inspection of steel tubes
Including fluorescence, coloring two kinds. Because of its simple equipment and convenient operation, it is an effective method to check the surface defect of magnetic particle inspection. It is mainly used for surface defect inspection of non-magnetic materials.
Q:RC is it welded steel pipe or galvanized steel pipe?
The basic knowledge of wire tubes - wire tubes, SC is welded steel pipe, RC is galvanized steel pipeThe basic wire pipe is the minimum requirement in the steel pipe. For so long, I wonder if you will adopt it
