During the use of Steel Structural Parts, regular inspection is an important part to ensure its safety and reliability. The following are some of the regular inspections that need to be carried out.
First, appearance inspection is essential. Check whether the surface of Steel Structural Parts has rust, wear, deformation, etc. Rust will reduce the strength and durability of steel, and rust removal and anti-corrosion measures should be taken in time. Wear may be caused by long-term use or friction with other objects. Severe wear may affect the bearing capacity of the structure. Deformation may be caused by external forces such as overload and earthquake, and its impact on structural stability needs to be further evaluated.
Secondly, inspect the welds. The welds are the key connection parts of Steel Structural Parts, and their quality is directly related to the overall strength of the structure. Non-destructive testing methods such as ultrasonic testing and magnetic particle testing can be used to check whether the welds have defects such as cracks, pores, slag inclusions, etc. For important welds, sampling destructive tests can also be carried out to determine their actual strength.
In addition, measure the dimensional changes of Steel Structural Parts. During long-term use, the steel structure may change in size due to various reasons, such as the vertical deviation of the column and the increase in the deflection of the beam. Use measuring instruments such as total stations and levels to regularly measure the dimensions of key parts, compare them with the design values, and determine whether the structure has undergone unacceptable deformation. If the deformation is found to exceed the allowable range, it is necessary to further analyze the cause and take corresponding reinforcement measures.
At the same time, check the tightness of the connecting bolts. Bolt connection is one of the common connection methods in steel structures. Loose bolts will reduce the integrity and stability of the structure. Use tools such as torque wrenches to regularly check whether the torque of the bolts meets the requirements, and tighten the loose bolts in time.
In addition, the anti-corrosion coating of the steel structure should also be inspected. The integrity of the anti-corrosion coating is crucial to prevent steel from rusting. Check whether the coating has peeling, blistering, cracking, etc. If there is a problem, it should be repaired or repainted in time.
For Steel Structural Parts used in harsh environments, such as seaside and chemical plants, the frequency and items of inspection need to be increased. For example, the corrosion rate of steel is monitored and chemical composition analysis is performed regularly to determine whether the steel is seriously affected by environmental factors.
In short, Steel Structural Parts need to be comprehensively and systematically inspected regularly during use to detect problems in a timely manner and take effective measures to deal with them, so as to ensure the safe and reliable operation of the steel structure.
