Product Description:

1、Structure of Welded Steel Pipe API SPEC 5CT:

Welded Steel Pipe is to be used for conveying gas, water, and petroleum foroil and natural gas industries. And used for structural steel pies purpose. 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.

Q:Seamless steel pipe is how to do it?
Probably with 10, 20, 30, 35, 45 and other high-quality carbon steel, 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other composite steel hot-rolled or cold rolled.
Q:What does carbon seamless steel pipe mean? What is the difference between a seamless 20# and an ordinary one? What is it used in detail?
Carbon steel is actually relative to alloy steel, mainly carbon content, and 20# seamless steel is carbon steel! In addition, there are stainless steel, stainless steel is considered a kind of alloy steel, but the processing is not the same, the performance is not the same, good looking outside!The description of the material in alloy steel is actually the content of the metal elements in the steel (usually the percentage number).
Q:What is the difference between the stainless steel pipe welded pipe and seamless pipe?
Grain size: usually, the grain size of the metal is related to the heat treatment temperature and the time at which the metal is kept at the same temperature. Therefore, the welded pipe and seamless tube annealing of the same grain size. If the minimum tube cold treatment, the grain size of the weld metal is smaller than the grain size, welding or grain size is the same.Strength: the strength of the pipeline in the composition of the alloy and alloy containing the same and the same heat treatment of seamless tube and seamed tube essentially consistent strength. After the tensile test and three-dimensional vibration test, tube tearing almost all occurred in the welding point or away from the heated area where. This is because there is little impurity in the weld and the nitrogen content is slightly higher, so the strength of the welded joint is better than that of other parts. However, the ASME Boiler and Pressure Vessel Association believes that the seamed tube can withstand 85% of the allowable pressure, which is mainly due to improved welding equipment data collection prior to today. The provisions of ASME 100% completely under license by ultrasonic testing pressure tube. Similarly, Europe and Asia also stipulates that can ensure the quality of welding performance by eddy current test tube, the eddy current testing is subject to legal procedures and licensed institutions. Trent's eddy current test was approved by the Swedish power division. ASME believes the current loss is relatively small, high-quality performance based on the seamed tube.
Q:Why can't stainless steel be put together with carbon steel tube?
Stainless steel can not be put together with carbon steel because of galvanic corrosion
Q:What is ND steel pipe?
ND steel 09CrCuSb steel is currently the most ideal "resistance to sulfuric acid dew point corrosion in steel (ND steel, ND steel, 09CrCuSb steel, 09CrCuSb steel), ND steel is widely used in the manufacture of economizer, served in the high sulfur content in flue gas of air preheater, evaporator and heat exchanger equipment for resist sulfur smoke gas dew point corrosion.
Q:How to calculate the maximum bending stress of steel pipe? Is there a list of the maximum flexural normal stresses for steel pipes of different materials and diameters?
Strength design of steel pipe by this formula to calculate the maximum normal stress in the steel pipe should be less than the value (based on your choice of different grades of steel, steel strength design value is not the same, this value can also be found through the design manual of steel structure), meet the requirements, it can meet the requirements of steel pipe under the action of bending moment strength.
Q:Material of welded steel pipe
GB/T3091-1993 (galvanized steel pipe for low pressure fluid delivery). Mainly used to transport water, gas, air, oil and heating, hot water or steam, etc. generally lower pressure fluid and other use tube. Its representative material is Q235 grade a steel.
Q:Difference between seamless steel pipe and welded pipe
Seamless steel pipe can be used in various industries, such as liquid, pneumatic, pipeline and gas pipeline.
Q:Are there specifications for scaffold steel pipe with 48mm * 3.2mm?
Previously used steel pipe GB 51*3.0mm, the latest national standard JGJ130-2001 stipulates that the use of steel pipe for construction projects need to be 48*3.5mm specifications, the wall thickness should be 3.5mm square for qualified products.
Q:What does "1.5" steel tube mean?
DN refers to the nominal diameter of the pipe (also known as nominal diameter), all piping accessories in the piping system are numerically represented in order to distinguish the parts that are represented by threads or outside diameters. Nominal diameter is used as a reference, after rounding the figures, and processing numerical value is not exactly the same, nominal diameter can be expressed as metric mm, also can be used in English in.
