Frequently Asked Questions
O.D. machining ensures a high-precision outer diameter that allows for a tighter, more secure fit within pressure vessel assemblies, significantly reducing the risk of leaks and vibration-induced wear.
They are extensively used in chemical plants, oil refineries, pharmaceutical manufacturing, and any industrial setting involving high-pressure metal packaging or piping.
While our standard range is 1/8" to 4", we offer custom machining services to meet specific project requirements for larger or non-standard dimensions.
Depending on the material selected (such as stainless steel), our couplings are designed to resist oxidation and chemical corrosion, maintaining structural integrity over time.
All products are manufactured according to international industry standards, and material certificates (MTRs) can be provided upon request to ensure quality compliance.
Parameter U and T refer to specific dimensional measurements (such as outer diameter and thickness/length) required for precise fitment in SPE-standard pressure systems.
