- Q: Does the seamless steel pipe need rust removal?
- The main use of steel wire brush and other tools to polish the surface of the steel, you can remove loose or tilted skin, rust, welding slag and so on. Manual tool derusting can reach Sa2 level, power tools derusting can reach Sa3 level, if the surface of the steel attached to the solid oxide sheet, tool rust removal effect is not ideal, can not reach the corrosion protection requirements of the anchor depth.
- Q: How are steel pipes measured and labeled?
- Steel pipes are typically measured and labeled based on their diameter, wall thickness, and length. The diameter is measured in inches or millimeters, while the wall thickness is often expressed in inches or schedule numbers. The length is usually specified in feet or meters.

- Q: Are steel pipes suitable for use in nuclear power plants?
- Yes, steel pipes are suitable for use in nuclear power plants. They are commonly used for various purposes including cooling systems, steam generation, and containment of radioactive materials due to their high strength, durability, and resistance to corrosion.
- Q: How do you calculate the pipe thermal expansion coefficient for steel pipes?
- In order to calculate the pipe thermal expansion coefficient for steel pipes, it is necessary to take into account both the linear expansion coefficient of the material and the temperature change. The typical linear expansion coefficient for steel is approximately 12 x 10^-6 per degree Celsius. To begin with, establish the initial length of the pipe, which is represented by L0. Then, measure the temperature change, indicated as ΔT. Proceed by multiplying the initial length of the pipe by the linear expansion coefficient and the temperature change: ΔL = L0 * α * ΔT. The resulting value, ΔL, signifies the alteration in length of the steel pipe caused by thermal expansion.
