1Structure of Seamless Pipe API SPEC 5L: 

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.

 

Standard: API SPEC 5L
● Application: To be used for conveying gas, water, and
petroleum for oil and natural gas industries

Q:What does "SC50" steel pipe mean in civil engineering?
The corrosion resistance of Ni is very strong in acidic environment. In the environment containing sulfuric acid or hydrochloric acid, the higher the content of Ni in the welded pipe is, the stronger corrosion resistance is. In general circumstances, the addition of Cr in a T-junction steel pipe prevents erosion. The marginal condition of the steel strip is another important cause of the wrong edges. The influence of mass flow rate, heat flux density and structural parameters (ratio of spiral curvature diameter and diameter of T-shape welded tube Dc/D) on heat transfer coefficient of saturated bubble boiling in vertical helical tubes.
Q:What are low-pressure carbon steel tubes?
Pipe fittingsA pipe fitting is a piece of pipe that is connected to a pipe. According to the connection method can be divided into socket type pipe fittings, threaded fittings, flange fittings and welding pipe four categories. Multipurpose; made of the same material as pipes. Elbow (elbow), flange, three pipe and four pipe (crosshead) and reducer (reducer) etc.. Elbow for pipeline corner; flange for the pipe and pipe interconnected parts, connected to the pipe end, three pipe for three pipe collection; four pipe for four tubes together place; for two pipes of different diameters connected to different diameter pipe.
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 steel pipes are buried for outdoor heating pipes? Seamless or welded tube? Are there any rules for specific countries? Can use the seamed tube?
The pipe material of heating pipe network should be designed according to the requirement. When the design is not specified, the following requirements shall be met:1 when the pipe diameter is less than or equal to 40mm, welded steel pipe shall be used.2 when the pipe diameter is 50 ~ 200mm, welded steel pipe or seamless steel pipe shall be used.3 when the pipe diameter is greater than 200mm, spiral welded steel pipe shall be used.
Q:What's the difference between No. 20 steel pipe and 27SiMn Steel Pipe?
27SiMn =27 - steel pipe, which is a seamless steel tube material, the carbon content in 0.24 - 0.32%, SIMN single because it five elements (carbon manganese silicon Si, C, Mn, P P, S, guimeng sulfur) the high content of about 1.10 - 1.40%.
Q:How to distinguish seamless pipe and welded pipe?
The way to distinguish seamless pipes and welded pipes is to see if there is weld marks on the port.
Q:What are the main types of steel pipe ah? How to judge which kind of steel pipe performance is better?
Welded steel pipe for different welding process and divided into the furnace pipe welding (ERW) pipe and automatic arc welding, because of the different forms of welding seam welded pipe and spiral welded pipe is divided into two kinds, end its shape is divided into circular welded and shaped (square, flat) pipe.The welded pipe is rolled into the steel tubular to sew or spiral seam welded in the manufacturing method, and is divided into low pressure fluid delivery with welded steel pipe, spiral welded steel pipe, welded steel pipe, welded pipe roll etc.. Seamless steel pipe can be used in various industries, such as liquid, pneumatic, pipeline and gas pipeline. Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.Press materialSteel pipe according to the pipe material (ie steel) can be divided into: carbon tube and alloy tube, stainless steel tube.Carbon tube can be divided into ordinary carbon steel tube and high quality carbon structure tube.The alloy tube can be divided into: low alloy pipe, alloy pipe structure, high alloy tube, high strength tube. Bearing tube, heat resistant acid resistant stainless pipe, precision alloy (such as cutting alloy) pipe, high temperature alloy tube, etc..
Q:When can I use the PVC pipe and when to use the galvanized pipe?
PVC pipeline use temperature is -5 to 90 degrees or so, according to the current market price of around 6000 yuan per ton, the price is cheap. Its corrosion resistance is good, can resist most of the acid and alkali, and unlike the steel pipe that is easy to rust, so in the construction of the upper and lower water pipes and other fields have gradually replaced the trend of steel pipe.
Q:Seamless steel tube 89X4 meters, how heavy?
According to the theory, each meter is 8.3844 kilograms. If you want to be precise, you'll lose your own weight.
Q:What is the theoretical weight per square meter of the steel pipe diameter of the outer frame and the thickness of the tube wall 3mm 48mm?
The outer steel tube diameter is 48mm, the tube wall thickness is 3mm, the theoretical weight per meter is 3.3291kgCalculation formula: (outside diameter wall thickness) * wall thickness *0.02466(48-3) *3*0.02466=3.3291kg
