ENERGY MACHINE, Oman, 42 Orders of Repeat Supply
Forty-two orders across five years, including a single release of more than a thousand two-inch ball valves. Repeat supply is a test of consistency rather than of capability.
ENERGY MACHINE, Oman, 42 Orders of Repeat Supply
ENERGY MACHINE placed forty-two orders with TSV between 2020 and 2024, which makes this the longest continuous supply relationship in our reference list. The valve types repeat: ball, gate and check valves in carbon steel and low-temperature carbon steel.
The largest single release was 1,123 two-inch Class 300 ball valves, which is a different manufacturing problem from a large-bore project. Volume work is won or lost on whether the thousandth valve matches the first.
The order in numbers
What was supplied
| Specification | Quantity | Rating / class | Valve types |
|---|---|---|---|
| 2" Class 300, carbon steel WCB | 1123 | IP65 | Ball valves |
| 10" Class 150, low-temperature carbon steel (LF2) | 57 | IP68 / seal class VI | Ball, gate, check |
| 6" Class 150, grade 5A | 11 | IP68 / seal class VII | Ball, gate, check |
A five-year relationship, not a single tender
Forty-two orders over five years means the specification was proven on delivery rather than on the quotation. Each release was built to the same drawings, with the same trim and the same test records, which is what makes a relationship like this continue.
It also means the buyer had opportunities to change supplier at every release and did not. In industrial valve supply that is the most meaningful endorsement available, because it is measured against deliveries rather than against promises.
What a 1,123-piece release demands
Volume changes the failure modes. Tooling has to hold its tolerance across a long run, material has to be available in the right grades in the right quantity, and the test bay becomes a production line rather than a bench.
The documentation has to survive the volume too. Every valve in a release of that size needs its test record, which means the record-keeping has to be organised before the run starts rather than assembled afterwards.
The buried and rated items
Several releases carried an enclosure rating for underground or chambered installation, and one carried a seal class stated by the customer as VII. Both requirements are settled at order stage and verified at the bench, which is why they belong on the enquiry rather than in a later conversation.
Questions this page answers
Because the buyer keeps choosing the same supplier against deliveries already received. It is measured performance rather than a quotation.
Every valve is shell and seat tested to API 598, with a record per valve. At that volume the sequence is planned in advance so the records are complete and traceable.
It is a material designation the customer named on the order. Where a project uses a non-standard designation, the grade and its test requirement are confirmed at enquiry stage before manufacture.
