Forged High Pressure 90 Degree Oilfield Wellhead Elbow
Product Description
This product is a high-pressure forged rotary elbow specially supporting oil wellheads and manifold systems. It is integrally forged from alloy steel, with internal and external surfaces sandblasted and coated with oil-resistant anti-corrosion red paint. Both ends adopt standard oilfield hammer union connections, and the middle rotary joint enables 360° free rotation to adjust pipeline installation angles.
It is widely applied to Christmas trees, choke manifolds, fracturing pipelines and gathering flowlines for high-pressure oil & gas transmission. Suitable for H₂S-containing sour oil and gas well service, it features anti-sulfur property, erosion resistance and reliable high-pressure sealing, serving as a core transition fitting for surface oil & gas processing systems.
Product Features
- 360° rotary design eliminates pipeline assembly stress, greatly simplifying on-site installation without forced pipeline alignment.
- Integral forging construction without welding seams delivers outstanding structural strength, preventing crack leakage under ultra-high pressure during fracturing and production operations.
- Optional CW2M nickel alloy body complies with NACE standards, providing superior resistance against corrosion from hydrogen sulfide, carbon dioxide and formation water for sour oil & gas wells.
- Combined metal & composite rubber sealing structure resists erosion from sediment and crude oil, ensuring zero leakage during long-term high-pressure operation.
- Standardized Fig series hammer union interfaces realize high interchangeability, directly matching wellheads, manifolds, high-pressure hoses and adjustable chokes.
- Optimized heat treatment balances toughness and rigidity, enabling stable performance in both cold open-air sites and high-temperature well conditions without brittle fracture or deformation.
- Full quality control: every unit passes hydrostatic strength test and MT/UT non-destructive testing; test reports and API monogram certification are available upon request.
- Long service life: wear-resistant anti-corrosion coating plus high-strength substrate outperforms cast fittings in impact and abrasion resistance, extending maintenance intervals. Complete sealing repair kits are supplied as spare parts for long-term operation.
