Eliminate Recurring Piping Failures, Talk to us

Piping failure is a loss of production , sometimes a small modification can solve major recurring problems.

Overview

ND Engineering Services provides expert troubleshooting solutions for piping systems. After stress analysis and recommendations with detailed drawings for modifications, we are able to solve most of the piping issues we have come across. 

Piping Failure Analysis

Stress analysis needs expensive software and skill. It is observed that many contractors end up installing lines without formal stress analysis to reduce cost and due to project completion pressure. Client find it very difficult to handle recurring issues during operation, arising out of faulty routing and supporting...

It is observed that many small and medium chemical manufacturers are not aware of the impact of the thermal expansion in hot piping and connected equipment. Companies end up attending recurring problems without addressing the core issue arising out of the thermal expansion in piping. Many times, a small change in supporting can solve major recurring leakage issues.

Steam is used as utility in food, pharma, wood and pulp, textile, automotive etc industry. Leakage and dislocation in steam line observed if analysis and supporting not done properly. Temporary solutions like rewelding at leakage points etc. never gives a permanent relief.

Some common piping problems experienced due to thermal expansion if proper analysis not performed

Leakages from pipes, tees & elbow cracks

Frequent pump bearing/seal failure

High misalignment during pump startup

Piping vibration

Failure at vessel attachments like nozzles, clips , trunnions etc

Flange leakage

Leakages from support weldings

Spring support failures like over elongation/bottomed out

Pipe support deformation / failure

Expansion Joint deformation / failure

List of Few major trouble shooting projects executed

Worked as a third party to solve pump seal failure issues in a polyester plant. This was to find the root cause of failure. ie poor engineering or faulty pump seal installed by vendor. This was to solve warranty dispute between pump supplier and consultant on seal failure of six pump sets

Vibration of a reciprocating pump line, there was a huge vibration observed when the unit was operating above 50% capacity. This was solved after analysis taking production to 96% capacity.

There was a bulging of a lateral tied expansion joint in a polyester plant and was on the verge of failure, this was solved by analysis and modifications.

Successfully solved some critical failures for companies like Indo Gulf Fertilizers, DFPCL, Garden Silk, RCF Itd, Balaji Amines and others
