New techniques/service for testing shoetracks to exacting standards

31 October 2010 I felt it was important to alert all members of a new development in the field of .. testing shoetracks to a proper standard.

Quote ..

"Did you know that most, if not all, float equipment is supplied un-tested?

Float equipment valves are usually designed, samples built and tested to an API approved test regime, but this is a type approval (API 10F) for that particular design and size of valve. The float equipment valves supplied to you may have been manufactured to a design that has passed the API approved testing regime but this does not require any acceptance testing post manufacture for individual valves that are subsequently used in the field. Moreover, an API type approved valve is then inserted into the float equipment steel hull vessel either by cementing it in or by threading and sealing it in some manner, but this valve and the finished assembly is not then tested. The valve is never flow tested nor back pressure or load tested as a unit before or after assembly into the steel hull
vessel. The valve or the installation method may fail against back pressure. The valve may fail to operate or hold back pressure after a nominal amount of flow has passed through it.

This means the float equipment you are supplied, other than dimensional checks, assembly checks and general QA/QC has not been tested post manufacture before you use it."

If you'd like to learn about the service that will exceed current requirements and test the 'shoes using testing equipment designed to API 6A (ISO10423) .. then read the attached.

It would be good to hear back from any members when they have used this important new service.
