Damage And Treatment Methods of Casing Pipe

There are four main types of common casing pipe damage, namely, crushing damage, breakage damage, anchoring damage and penetration damage. What are the specific situations of these damage types? How to deal with these problems?

Crushing damage

Crushing is a common type of casing pipe damage. The cause of crushing may be that the casing pipe is squeezed by other objects during transportation, or deformed due to excessive mechanical force.

For crushing damage, the following two treatment methods can be adopted:

1.Replace the damaged parts and select parts that meet the requirements for replacement.

2. Strengthen the protection measures of the casing pipe, such as thickening the packaging, tying around the casing pipe, etc., to avoid crushing damage.

Crack damage

Crack damage is a more serious type of casing pipe damage. Damage may be caused by excessive impact or abrasion of the casing pipe.

Damage generally requires repair or replacement. Specifically, the following two treatment methods can be adopted:

1. Small area damage can be bonded or reinforced.

2. Large-area damage requires replacement of damaged casing pipe.

Anchoring damage

Casing pipe detachment from the fixed position is called "anchoring", which generally occurs during the operation of the casing pipe.

The treatment methods for anchoring damage are:

1. Regularly check the casing pipe fixing device and replace the aging casing pipe fixing parts in time.

2. Install a gasket at the fixed position of the casing pipe to prevent the casing pipe from detaching from the fixed position.

Leakage damage

Casing pipe leakage may be caused by poor casing pipe sealing or cracks in the casing pipe itself.

For leakage damage, the following two treatment methods can be adopted:

1. Replace casing pipe with poor sealing or more cracks.

2. Take remedial measures at the casing pipe leakage, such as adding seals or bonding.

In summary, the types of casing pipe damage are relatively diverse, and different treatment methods need to be adopted according to the specific situation. Whether it is replacement or reinforcement, the key is to improve the protection measures of the casing pipe and regular inspection and maintenance.
