How to protect seamless steel pipes in daily life?

Seamless steel pipes are produced from a solid, hollow steel billet, which is then processed without any welding on the surface. These pipes are called seamless due to the absence of welds.

Based on the manufacturing process, seamless steel pipes can be classified into several types, including hot-rolled, cold-rolled, cold-drawn, extruded, and jacked pipes.

Seamless steel pipes are also categorized by their cross-sectional shape, which can be round or special-shaped. Special-shaped pipes come in a variety of complex shapes, such as square, oval, triangular, hexagonal, melon seed, star, or winged. The maximum diameter of seamless steel pipes can reach 900 mm, while the minimum is 4 mm.

To ensure the longevity and integrity of seamless steel pipes, regular maintenance is essential. Here are some key maintenance practices:

Proper Handling:

When lifting seamless steel pipes, avoid pulling the wire rope at an angle to prevent it from coming out of the groove.

Stability During Operation:

Ensure that both personnel and equipment are stable and safe during operation.

Inspection of Stability Switches:

Regularly check the stability switches before and after the trolley, as well as the sensitivity and operability of the stability switch at the maximum hook lift limit.

Lubrication:

Regularly lubricate the gears, sprockets, chains, ropes, and other moving parts of the equipment associated with seamless steel pipes.

Cooperation with Crane Operators:

When operating the cantilever crane, work closely with the crane operator and follow the crane's instructions.

Full Loading of the Hook:

Ensure that the hook is fully loaded with coils during lifting operations.

Wire Rope Maintenance:

Replace the wire rope if 10% of it is found to be broken.

Brake Inspection:

Frequently check the hook lifting brake to ensure it is functioning properly and responsively.

Gentle Lifting and Lowering:

When lifting seamless steel pipes with steel coils, do so gently and steadily, ensuring accurate, stable, and light operation.
