Olet Fittings

Benefits

• Precision Machined Thread Taper: The internally threaded profile features high-accuracy NPT/BSP threads to ensure complete sealing engagement with male pipe ends, preventing pressurized fluid leakage.

• Integrally Reinforced Junction: The forged body distribution layout completely eliminates the risk of structural cracks or catastrophic fatigue failure at the branch intersection under severe line pulsing.

• Streamlined Manifold Fabrication: Replaces traditional full-sized reducing tees by requiring only one contour weld seam, significantly decreasing welding time and non-destructive radiography testing costs.

  Applications

  These specific olet fittings are extensively used in high-pressure processing lines to tap small instrument connections into large-diameter product headers. In chemical processing utilities, Stainless Steel and High Nickel Alloy Thredolets are welded to main process lines to attach pressure transmitters and thermowells, shielding the sensor attachment from localized chemical pitting. The oil and gas refining sector relies heavily on heavy-duty Carbon Steel Weldolets to construct multi-line branch manifolds for crude oil routing where the fittings absorb severe hydraulic pressure surges. In thermal power stations, Alloy Steel branch connections are integrated into main steam supply loops to manage auxiliary drainage lines safely under extreme thermal expansion conditions. Additionally, marine engineering platforms employ corrosion-proof Cupronickel branch ports on centralized seawater cooling lines to hook up diagnostic tools without introducing localized structural weakness or flow restriction.
