I am given a project on Revamp of Spring Supports at an Ammonia Plant where I work as a Maintenance Engineer. We are facing serious issues during the project, and hence I need guidance from experienced persons in the field.
Briefly described, our plant was relocated from a place where it was in operation for almost 20 years before it was mothballed. Since its relocation, the plant has been in operation for 20 years. The plant, and hence the spring supports, are in service for almost 40 years. The supports are mostly installed on services having pressures greater than 1500 psi and temperatures higher than 400 F.
We have planned to execute the project in the following phases:
1. Carry out audit of the existing facility and identify the spring support conditions.
2. Identify the faulty supports and take corrective action.
3. Develop Preventive Maintenance (PM) plans for the supports.
For this I need guidance on following:
1. For the audit, we are visually inspecting the supports to see whether the springs are over or under loaded, conditions of supports, conditions of locking nuts and signs of corrosion. Can we add any thing else that can increase our understanding of the current condition?
2a. Does anyone has any experience of repairing the spring supports?
2b. Are there any vendors which offer cheaper solutions for repair / reclamation of supports?
2c. Can we purchase any used spring supports which are in a better conditions? If so, where to look for them?
2d. Can we replace a spring supports on-line? i.e. while the line is in service?
2e. What are the codes and standards which govern the installation / maintenance of supports?
3a. Are there any standards which guide about PM plan for supports?
3b. Does anyone has any experience in this regard?
Thank you for being patient and for any advice that you can give. :-)
Regards,
