The Problem:
Hytorc needed a simplified reliable Bolt Load Measurement method that was comparible to well controlled laboratory measuring rods that would work at high temperatures for research. The study was on the impact of Bearing Face Knurling on bold load relaxation at elevated temperatures.
The Consequence:
"The RT-Bolts worked very well! We were very impressed with the repeatability of the measurements. I have spent years...
The Problem:
Compact flanges were used on a NPS 40 gas line on an offshore platform. The compact flange joints proved very difficult to seal during assembly and commissioning. They are also likely to be difficult to maintain, as small imperfections can cause leakage of the seal ring. A back-up plan was formulated that involved using a kamprofile gasket in place of the compact seal ring. This required very accurate joint assembly, in order to ensure that an adequate...
The Problem:
Coke Drums operate at high temperature and
see extreme cycles of operation every 24 hours. Most sites using delayed cokers have had leakage problems with the joint between the bottom deheading valve and the coke drum or coke drum transition spool.
The Consequence:
Joint leakage can escalate to the point where ignition is possible, requiring the unit to be taken offline to repair the joint. This leads to several days of...
The Problem:
A refinery had continuous nuisance leakage from a bank of high temperature heat exchangers with 3/4” bolts. Assessment of the joint integrity revealed that an extremely high assembly bolt load (90% of yield) was required in order to ensure good joint integrity.
The Consequence:
Leakage of these joints was problematic for the re nery, requiring shutdown to retighten the joints and, on occasion, shutdown to replace the gaskets...
