Titanium Slip Joint

Our Titanium Slip Joint (also known as titanium slip expansion joint, titanium telescopic joint, titanium slip fitting) is a critical compensating connection component for industrial piping systems. It is designed to absorb axial displacement caused by pipeline thermal expansion and contraction, mechanical vibration, installation misalignment, while eliminating system stress, protecting core equipment (pumps, valves, heat exchangers), and enabling quick disassembly for pipeline maintenance and inspection.

We offer a full range of structural types (basic, restrained anti-pullout), connection forms (flanged, welded, threaded, sanitary clamp) and material grades, fully adapting to low-pressure to ultra-high pressure, general to extreme corrosive working conditions. Widely used in chemical processing, seawater desalination, marine engineering, offshore oil & gas, pharmaceutical & biotechnology, power generation, flue gas desulfurization and other industries.

1.Superior Axial Displacement Compensation :

Standard axial travel ranges from 50mm to 200mm, with customizable travel up to 500mm. Effectively absorbs axial displacement of pipelines caused by temperature changes, eliminates thermal stress in the piping system, prevents pipeline deformation and cracking, and extends the service life of the entire system.

2.Industry-Leading Corrosion Resistance :

Unparalleled corrosion resistance in seawater, high chloride ion environments, strong oxidizing acids, alkalis, and reducing media. Standard Grade 2 titanium slip joints outperform 316L stainless steel in 90% of corrosive conditions; Grade 7 titanium slip joints with palladium addition provide exceptional crevice corrosion resistance in extreme reducing acid and high-temperature brine environments, suitable for the harshest chemical and offshore working conditions.

3.Multi-Layer Reliable Sealing Design :

Adopt dual/triple sealing structure, standard equipped with PTFE (Polytetrafluoroethylene) sealing rings, optional EPDM, FKM/Viton, graphite, Inconel-reinforced PTFE seals for different media and temperatures. The sealing system achieves zero leakage, excellent wear resistance and long service life, with on-site replaceable seals for low-cost maintenance.

4.Restrained Anti-Pullout Safety Design ：

Optional restrained structure with limit bolts and baffle plates, which restricts the maximum expansion displacement, effectively prevents the inner sleeve from pulling out of the outer body under pressure surge, water hammer, pipeline vibration or fixed support failure, ensuring safe operation of the system and avoiding pipeline disconnection accidents.

5.Ultra-Low Installation & Maintenance Cost ：

Split sliding structure enables quick installation and disassembly without welding, greatly reducing downtime for pipeline maintenance and overhaul. No special tools are required, and seals can be replaced quickly on site, lowering the total life cycle cost of the system.

6.Wide Temperature & Pressure Adaptability ：

Working temperature ranges from -200℃ (cryogenic environment) to 450℃, working pressure from full vacuum to PN100 (Class 600). Fully adapts to all working conditions from cryogenic engineering to high-temperature chemical processing, from low-pressure water supply to high-pressure oil & gas pipelines.

7.Full Connection Form Compatibility ：

Provide flanged, butt welded, threaded (NPT/BSPT), socket welded, sanitary clamp connection forms, compliant with ASME B16.5, EN 1092-1, JIS B2220 and other international flange standards. Perfectly compatible with existing titanium piping systems without additional modification.

8.Food & Pharmaceutical Grade Sanitary Compliance ：

Q: What is the difference between a Titanium Slip Joint and a Titanium Bellows Expansion Joint?

A: The core difference lies in the compensation principle, structure and application scenarios.

- Titanium Slip Joint : Realizes axial displacement compensation through the sliding fit between inner and outer sleeves, with simple structure, large compensation amount, high pressure resistance, long service life and low maintenance cost. It is suitable for straight pipeline systems with mainly axial displacement, can withstand high temperature, high pressure and corrosive media, with lower cost for large diameter pipelines.

- Titanium Bellows Expansion Joint : Realizes displacement compensation through elastic deformation of metal bellows, can compensate axial, lateral and angular displacement, but has lower pressure resistance, shorter service life in corrosive media, and higher cost for large diameters. It is suitable for complex pipeline systems with multi-directional displacement.We can recommend the most suitable type according to your pipeline layout, displacement type and working conditions.

Q: What seal material should I choose for my titanium slip joint?

A: The seal material is selected according to your working medium, temperature and pressure:

- PTFE (Polytetrafluoroethylene) : Standard configuration, excellent corrosion resistance, wide temperature range (-180℃ ~ 260℃), suitable for most corrosive media, strong acid and alkali, seawater, the most versatile option.

- EPDM : Excellent weather resistance, suitable for water, seawater, weak acid and alkali, temperature range -40℃ ~ 120℃, low cost, ideal for water supply and drainage, seawater desalination systems.

- FKM/Viton (Fluororubber) : Excellent oil resistance, high temperature resistance, corrosion resistance, temperature range -20℃ ~ 200℃, suitable for oil, organic solvents, high temperature corrosive media.

- Graphite + Inconel Reinforced PTFE : For high temperature, high pressure, strong corrosion extreme working conditions, temperature range up to 450℃, excellent wear resistance and creep resistance.We can customize the seal material according to your specific working conditions.

Q: What is the difference between restrained (anti-pullout) and basic titanium slip joint? When should I choose the restrained type?

A: The core difference is the safety protection function:

- Basic Type : Only has sliding compensation and sealing function, no displacement limit, simple structure, low cost, suitable for pipelines with fixed supports on both sides, no pressure fluctuation, stable displacement, and no risk of pipeline pullout.

- Restrained Anti-Pullout Type : With limit bolts and baffle structure, it can limit the maximum expansion and contraction displacement, effectively prevent the inner sleeve from pulling out from the outer body under extreme working conditions such as pressure surge, water hammer, pipeline vibration or fixed support failure.You must choose the restrained type in the following scenarios: high pressure pipelines, pump outlet pipelines, pipelines with pressure fluctuation or water hammer, long-distance pipelines, buried pipelines, pipelines without sufficient fixed supports on both sides, and pipelines with high safety requirements.

Q: Can your titanium slip joint be used in seawater and high chloride ion environments?

A: Yes, absolutely. Our titanium slip joints are made of high-purity titanium and titanium alloys, which have unparalleled corrosion resistance in seawater and high chloride ion environments, far exceeding 316L and duplex stainless steel. Standard Grade 2 titanium slip joints can be used in seawater for a long time without corrosion, and Grade 7 titanium slip joints with palladium addition can provide extra crevice corrosion resistance in high-temperature, high-concentration chloride ion environments. They are the ideal choice for seawater desalination, marine engineering, offshore platforms, and coastal power plant circulating water systems.

Q: What installation precautions should we pay attention to for titanium slip joints?

A: Key installation precautions to ensure long-term reliable operation:

- The slip joint must be installed on a straight pipeline section, and the axis must be consistent with the pipeline axis, no eccentric installation is allowed.

- Fixed supports must be set on both sides of the slip joint to ensure that the pipeline does not exceed the rated travel. For the basic type, the fixed support must be able to withstand the pipeline thrust; for the restrained type, the limit bolts must be adjusted to the rated travel before installation.

- The sealing surface must be protected from damage during transportation and installation, and foreign matter must not enter the sliding cavity to avoid seal wear and leakage.

- Welding operation near the slip joint must be completed before installation, to avoid welding spatter damaging the sliding surface and seal.

- After installation, the sliding part must be free of jamming, and the pressure test must be carried out according to the rated working pressure.We can provide detailed installation manuals and on-site installation guidance services.
