On-shore GOSP, KSA

 
 

Application Date:

2013

 
 

Application Situation:

The pipe line is nearly 25 years old and the Expansion joints # 3 & 4 started leaking during the start up. Under such circumstances, considering the safety of the plant & personnel, the customer opted to go for the repair and refurbishment of all the Expansion joints.

 
 

Problem:

During the start-up, the 34inch expansion joints in the flare header started leaking due to which the plant was forced to shut down under emergency situation. The customer called various contractors to sort out their problem and they could not find any proper solution. 

 
 

Products:

Belzona 4301

Belzona 4311

 

 

Substrate:

Rubber

 
 

Application Method:

The application was carried out in accordance with modified Belzona Know-How System Leaflet SHM-12. Belzona 9211 non-slip aggregate was embedded in  Belzona 2111 applied in chevron designed stripes.

 
 

Belzona Facts:

The customer had invited two major contractors and the solution provided by them was to replace the whole pipe line along with the latest “U” type expansion joints. The cost & time for replacement was very high. Both these contractors are not ready for repairing the expansion joints due to non – availability of Technical specs / drawings. Another “On line leak sealing” solution provider offered a solution to arrest the leakage of the expansion joints which is basically a clamping system. Technical evaluation was done by the customer’s technical team and they rejected the solution because the clamping system shall not allow the expansion joints to expand or contract.
