Proper pre-installation preparation is the most critical step to eliminate field leakage for RTJ gasket connections. Even tiny defects or […]

RTJ (Ring Type Joint) gaskets are vital high-pressure sealing parts for oil, gas and petrochemical plants. Rigorous incoming inspection is

The oil and gas sector is the most dominant end market for RTJ (Ring Type Joint) gaskets. Featuring outstanding high-pressure

RTJ ring joint gaskets are precision sealing components widely used for high-pressure working conditions in the oil and gas, chemical,

Inconel 625 – Up to 1000°C, excellent oxidation and corrosion resistance, suitable for H₂S (hydrogen sulfide) / CO₂ environments. Ideal

Oil & gas – Wellheads, Christmas trees (API 6A), subsea manifolds, high-pressure pipelines and valves. Refining & petrochemical – Catalytic

Two core mechanisms: Plastic deformation (coining) – Bolt preload compresses the gasket, causing controlled local plastic deformation (not full permanent

ASME B16.20 covers dimensions, tolerances, materials, and marking for metallic gaskets used with ASME B16.5 and B16.47 flanges. It includes

Both are ASME B16.20 R‑type gaskets with the same R numbers. Their key differences lie in cross‑section geometry. Oval type

ASME B16.20 defines three core RTJ gasket designs for high-pressure sealing services. R type – The conventional basic design, suitable
