Product Description:

1Structure of Straight Welded Steel Pipe: 

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 Straight Welded Steel Pipe:

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

• Reasonable price

Q:What does "buried steel pipe" 6*2SC100 mean?
This is the electrical drawings, such as water supply and drainage, HVAC is that DN, SC is the laying of electrical wiring, which is defined as threading pipe laying. 100 is the nominal diameter of the pipe, unit millimeters.
Q:What are the uses of welded steel pipes?
The spiral submerged arc welded pipe (SY5036-83) for the delivery of pressurized fluid is made of hot rolled steel strips for tube billets, often spirally formed, welded by double submerged arc welding and used for the transmission of pressurized fluid. The steel pipe has strong pressure bearing ability and good welding performance. After a rigorous scientific examination and test, it can be used safely. The utility model has the advantages of large caliber of the steel pipe, high transmission efficiency, and investment in laying pipelines. Mainly used in the transportation of petroleum and natural gas pipelines.
Q:What is the difference between steel pipe and round steel?
Making ring parts with steel tubes can improve data application rate, simplify manufacturing process, save data and work hours, such as rolling bearings, rings, Jack sleeves, etc., and have been widely used in steel pipe manufacture.
Q:What's the difference between straight steel pipe and seamless steel pipe?
The welded pipe is made of rolled steel plates, and small ones are straight welded, and big ones are spiral welded. Because the welded pipe has weld, the mechanical performance of weld is poor, so its applicable range is limited, but its price is cheap. Significant difference is that there are welded pipe, seamless steel pipe is not, of course, the welded pipe treatment of good, layman do not see the difference.
Q:Will the steel tube dance?
The steel tube dance tube has a rotating steel tube and a fixed steel tube, so that different types of steel pipe can be chosen according to the type of pipe dance performed by the dancer.
Q:What is hot rolled steel pipe? What is a cold drawn steel tube?
Hot rolling is relative to cold rolling, cold rolling is performed under recrystallization temperature, while hot rolling is rolling above recrystallization temperature.
Q:Is the steel frame on each floor supporting formwork (floor) called full scaffolding?
After the use of full scaffolding, more than 3.6 meters of interior wall decoration is no longer calculated decorative scaffolding, and the interior wall of the scaffolding is still in accordance with the provisions of the scaffolding.
Q:Seamless steel pipe 8162 and 8163 what is the difference?
8163 GB is fluid delivery tube, need to use eddy current detection, fluid transport, liquid, gas, solid, such as natural gas, water, gas, coal and stone, 8162 and 8163 of the popular point that is 8163 more than 8162 senior, 8163 inspection, 8162 inspection. I hope you understand!
Q:How many fasteners are there in a ton of steel tubes?
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:What does "steel pipe SC" mean?
DN100 and "SCH80" refer to the outer diameter and the wall thickness of the steel pipe;
