Oil & Gas Industry

The oil and gas industry demands sealing solutions that can withstand extreme pressures, high temperatures, and aggressive environments. Kaxite Sealing provides oval and octagonal ring joint gaskets for critical applications including:

  • Pipeline flanges and connectors
  • Wellhead and Christmas tree assemblies
  • Refinery processing units
  • High-pressure manifolds and valves
  • Compressor stations and pump systems

Our gaskets are manufactured in materials such as stainless steel (304, 316, 321), Inconel, Monel, and soft iron – all compliant with API 6A and ASME B16.20 standards, ensuring safe and reliable performance in the most demanding upstream and downstream applications.

Subsea & Offshore

Subsea operations require sealing solutions that can withstand extreme hydrostatic pressure, seawater corrosion, and thermal cycling. We specialize in RX, BX, and AX ring gaskets for:

  • Subsea wellhead connectors
  • High-pressure riser systems
  • Subsea Christmas trees and manifolds
  • Offshore production platforms

Our subsea gaskets are produced with full traceability (MTC per EN 10204 3.1) and comply with NORSOK M-710 requirements, providing the reliability needed for deepwater installations.

Chemical & Petrochemical

Chemical processing environments expose gaskets to corrosive media, high temperatures, and pressure fluctuations. Kaxite Sealing offers ring joint gaskets in Inconel, Monel, Titanium, and Hastelloy for:

  • Reactor vessel connections
  • Heat exchanger flanges
  • High-temperature piping systems
  • Acid and corrosive media handling

Our corrosion-resistant materials ensure long service life and minimal maintenance in aggressive chemical environments.

Power Generation

Power plants rely on leak-proof sealing for steam, gas, and fluid systems operating at extreme temperatures and pressures. We supply RTJ gaskets for:

  • Steam turbine connections
  • Boiler feedwater systems
  • High-pressure steam piping
  • Heat recovery steam generators (HRSG)

Our gaskets maintain sealing integrity under thermal cycling and high-temperature conditions, ensuring operational efficiency and safety.

Marine & Shipbuilding

The marine industry requires sealing solutions that resist seawater corrosion and withstand vibration and shock loads. We provide CCS-approved ring joint gaskets for:

  • Marine engines and propulsion systems
  • Propeller shaft seals
  • Seawater cooling systems
  • Deck machinery and hydraulic systems

Our gaskets are manufactured from marine-grade materials including stainless steel and Monel, ensuring durability in harsh marine environments.

Custom OEM / ODM Solutions

Beyond standard ring joint gaskets, Kaxite Sealing offers comprehensive OEM and ODM services. We can produce custom non-standard sizes, special materials, and unique designs based on:

  • Your engineering drawings or CAD files
  • Physical samples for reverse engineering
  • Custom material specifications
  • Special surface finishes and coatings

Our engineering team works closely with clients to develop bespoke sealing solutions that meet specific performance, regulatory, and operational requirements.
