Product Description:

1Structure of Hot Rolled Seamless Steel pipe Made in China: 

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. 

 

2‍‍Main Features of Hot Rolled Seamless Steel pipe Made in China:

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

• Reasonable price

Q:What are the lengths of scaffold steel tubes?
Used to build scaffolding of steel pipes in general have two kinds, an outer diameter 48mm, wall thickness 3.5mm; another kind of outer diameter 51mm, wall thickness 3mm; according to its location and role of different, can be divided into vertical pole, horizontal rod, sweeping rod, etc.. According to the technical specification for construction of steel tubular scaffold with couplers, JGJ 130 - 2011[1]. The scaffolding steel pipe should be specified with the current national standard "GB/T13793" or "straight seam welded steel pipe welded steel pipe for low pressure liquid delivery" GB/T3091 Q235 ordinary steel pipe; steel pipe steel quality should meet the requirements of current national standard grade Q235 steel "carbon structural steel" in GB/T700. The scaffold pipe shall be made of a diameter of 48.3 * 3.6 steel tubes. The maximum mass of each steel tube shall not be greater than 25.8kg.
Q:Seamless steel pipe and welded pipe what is the difference?
Identification method: see the inside of the pipe, because the external, will deal with the welded pipe is inside a gap, you can see some, some, is not easy to see, you can slowly by hand touch, or see the specifications are relatively thin, welded pipe
Q:How to identify stainless steel pipe and steel pipe?
Stainless steel (Stainless Steel) is referred to as the stainless steel, the resistance of air, steam, water and other weak corrosive medium or with stainless steel known as stainless steel; while the resistance to chemical corrosion (acid, alkali and salt chemical etching) corrosion of steel called acid resistant steel. Because of the difference in the chemical composition of the two, and make their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid resistant steel are generally stainless steel.
Q:How many meters per ton of steel tube?
Metric tons are metric units and China adopts metric system, so what we Chinese usually say "ton" means "metric ton", which can be regarded as "metric ton"1 metric tons (tonne/metric ton) = 1000 kg1 tons = 1000 kg1 kg = 1000 grams
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's the difference between steel pipe and pipe fittings?
Steel: steel pipe is a hollow steel strip, used as pipe conveying fluid, such as oil, gas, water, gas, steam, in addition, the bending and torsional strength of the same, the weight is light, so it is widely used in the manufacture of machinery parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
Q:How can seamless steel tubes be produced?
Seamless steel tubes are made of ingots or billets made by piercing and are then made by hot rolling, cold rolling or cold casting. Seamless steel tube plays an important role in the steel tube industry of our country. According to incomplete statistics, China's existing seamless tube production enterprises about more than 240, seamless steel pipe units about more than 250 units, with an annual output capacity of about about 4500000 tons. From the caliber, 35% of phi 76, less than phi 159-650, accounting for 25%. From the species point of view, the general use of 1 million 900 thousand tons of pipe, accounting for 54%; oil pipe 760 thousand tons, accounting for 5.7%; hydraulic props, precision pipe 150 thousand tons, accounting for 4.3%; stainless steel pipe, bearing tube, automobile tube 50 thousand tons, accounting for 1.4%.
Q:What are the specific differences between flexible pipes and rigid pipes?
Choose from the waterproof performance:A rigid waterproof sleeve is a steel pipe with an outer wing (a steel ring made of a steel ring), mounted in the wall (mostly concrete walls), used for general pipe wall crossing, and is beneficial to the waterproof of the wall;The flexible waterproof casing except external wing ring, flange ring and internal wire like, and have complete sets sold, but also their own processing, for pipeline damping needs, such as pipes and pumps connected through walls.
Q:Is there any difference between HFW steel pipe and ERW steel pipe?
The difference between ERW (longitudinal resistance welding) and HFW (high frequency welding) is mainly due to the different principle.
Q:What does GALV mean in a steel tube?
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.
