FAQ:
where can i buy 6 round steel pipe?
If your purchase quantity is relatively small, it is recommended to purchase through a local metal supermarket. If the purchase quantity is relatively large, it is recommended to purchase directly from round tube factories such as Yuantai Derun, which is more cost-effective.
What is round steel pipe used for?
Many round steel pipes are used in the fluid transportation industry, such as the transportation of oil, natural gas, water, etc. A small number are used to manufacture mechanical components and apply them to steel structures.
What is the difference between round pipe and round tube?
There are several important distinctions between tubes and pipes: a pipe serves as a vessel, while a tube is considered structural. Pipes are measured by their inside diameter (ID), whereas tubes are measured by their outside diameter (OD).
How to Bent round steel pipe?
The method of manually bending a round steel pipe includes the following steps:
1、 Before bending the round steel pipe, it is necessary to prepare some fine sand and two plugs in advance. Firstly, seal one end of the pipe with a plug, then pour fine sand into the round steel pipe, and finally seal the other end of the round steel pipe with another plug.
2、 Before bending, place the circular pipe section that needs to be bent on a gas stove and heat it for a period of time to reduce the hardness of the pipe, making it softer and easier to bend. When heating, keep rotating to ensure uniform heating around the entire circumference of the tube.
3、 Prepare the roller according to the required bending shape and size of the round steel pipe, and fix it on the cutting board. Hold one end of the round steel pipe with one hand and the other end with the other hand. Place the part that needs to be bent against the roller and gently bend it with force to easily achieve the desired curvature.
In addition to manual bending, machines can also be used. Pipe bending machine is a device that can be used for both bending pipes and as a jack. It is mainly divided into CNC pipe bending machine and hydraulic pipe bending machine, and is widely used in pipeline laying and maintenance work in fields such as power construction, railway construction, bridges, and ships.
How to calculate the weight of round steel pipes?
The formula for calculating the weight of a circular steel pipe is: weight (kg)=π/4 × (outer diameter ^ 2- inner diameter ^ 2) × length × density, where π ≈ 3.14159, the units of outer and inner diameters are mm, length is m, and density is kg/m ³.
how to make a round steel pipe from plate steel?
ERW Round Steel Pipe Making Process: Uncoiling->Shear welding->roll forming->High-frequency welding->Sizing->Cutting->Testing->Package to storage
LSAW Round Steel Pipe Making Process: Test->Steel plate trimming->Pre bending->JOE cold forming->Pre welding->inside welding->External welding->Sizing->Testing->Packaging and storage
