Kadant plays a vital role in the oil and gas industry, delivering durable and reliable technologies that improve safety, efficiency, and sustainability across both upstream and downstream operations. Innovative rotary joints and unions are trusted in demanding applications such as coiled tubing, top drive drilling, offshore platforms, and refining processes, where secure fluid transfer under high pressures and temperatures is essential. Their full line of expansion joint technologies, including rubber, PTFE, metal bellows, and joints help absorb thermal movement, reduce piping stress, and control vibration in critical processing systems. With advanced rotary sealing solutions and expansion joint technologies, oil and gas companies can achieve greater equipment reliability, safer operations, and more sustainable performance in some of the industry’s most challenging environments.
ELSX™ Rotary Joints
The ELSX rotary joint is engineered for extended-life steam and thermal oil service in oil and gas operations. Designed to perform in high-pressure, high-temperature, and vibration-intensive environments typical of refining and petrochemical facilities, this robust equipment incorporates a convex seal geometry that increases pressure-velocity (PV) capability by up to 20% and extends seal ring life by up to 15% over traditional rotary joint designs. This advanced sealing technology enhances equipment reliability, reduces unplanned outages, and delivers consistent thermal performance in continuous, mission-critical processing applications.
Liqui-Mover™ Pumps
Kadant Liqui-Mover pumps provide reliable, maintenance-efficient fluid movement across multiple stages of oil and gas operations, particularly where conventional pumping systems struggle. Commonly deployed on offshore platforms, upstream production sites, and remote midstream facilities, these pressure-powered pumps excel at moving condensate, produced water, and other process liquids without the need for electrical power. Their simple, robust design increases system reliability in hazardous or hard-to-access locations, while improving energy recovery by returning valuable condensate to heat-recovery and processing systems. Built for demanding environments, Liqui-Mover pumps deliver long-lasting performance that supports safer and more efficient operation throughout the oil and gas industry.
Over-The-Shaft (OTS) Rotary Unions
Kadant over-the-shaft (OTS) rotary unions are a robust solution for oil and gas production processes that require heating, cooling, or fluid transfer. Built with stainless-steel, bronze, and aluminum components for corrosion resistance and long service life, these custom-engineered rotary unions are configured to match each application’s size, number of ports, and operating conditions. High- and low-speed designs, along with options that support easy removal and field repair, help oil and gas processors reduce maintenance downtime and keep critical production assets running reliably.
Custom Rotary Union
Custom rotary unions are essential components throughout the oil and gas industry, supporting critical rotary fluid-transfer needs in upstream drilling equipment, offshore swivel stacks, frac pumps, top drives, mud agitators, and pipeline maintenance systems. These unions must withstand extreme pressures, abrasive media, and volatile hydrocarbons while ensuring reliable sealing performance in both onshore and offshore environments. Kadant engineers rotary unions specifically for these conditions, offering solutions built from advanced materials such as Inconel or corrosion-resistant stainless steels, as well as multi-passage designs for simultaneous transfer of drilling fluids, hydraulic oil, and chemical additives. Each custom configuration is designed to maintain stringent sealing integrity, extend service life, and meet the demanding operational and safety requirements of today’s oil and gas applications.
Expansion Joints and Flexible Metal Hoses
Kadant expansion joints and flexible metal hoses are essential components in the steam, condensate, and process piping systems that support the oil and gas industry. Found in various locations throughout production processes, expansion joints manage thermal expansion, vibration, and equipment movement under high-temperature and pressure conditions. Expansion joints absorb thermal growth, reduce system stress, and prevent leaks in pipelines carrying steam, condensate, and exhaust gases, while flexible metal hoses compensate for misalignment and movement between critical equipment. Together, they ensure safe, reliable, and efficient operation of process piping systems.
Jet Products
Kadant jet products provide precise steam pressure and temperature control in oil and gas operations. Thermocompressors capture and recompress low-pressure steam by blending it with high-pressure motive steam, enabling energy recovery and reducing overall steam consumption. Desuperheaters inject controlled amounts of water into superheated steam to produce stable, saturated steam for efficient heat transfer in reboilers, heat exchangers, and thermal processing equipment, enhancing energy efficiency, process stability, and reliability across refining and petrochemical facilities.
