KINJOINT SSEJ-250T-SG is a threaded stainless steel bellows expansion joint from Kinetics Middle East for HVAC, mechanical and industrial piping systems requiring controlled thermal movement. The model is available with BSPP, BSPT and NPT threaded-end configurations, 16 or 25 bar working-pressure options and a working-temperature range of −50°C to +450°C. Standard technical drawings cover ±25 mm axial movement, with a separate 25 bar configuration available for ±50 mm axial movement. Kinetics Group supports consultants, MEP contractors and engineering project teams in the UAE, GCC and wider MENA region.
Engineered for Performance.
KINJOINT SSEJ-250T-SG is a threaded stainless steel bellows expansion joint engineered to accommodate dimensional changes in piping caused by thermal expansion and contraction. Its compact bellows construction provides an engineered alternative to space-consuming pipe loops and maintenance-dependent slip-type joints where a bellows expansion joint is suitable for the piping design.
Designed for HVAC, mechanical and industrial piping applications, the SSEJ-250T-SG is available with threaded BSPP, BSPT and NPT connection options. The SG configuration incorporates tie/control rods for movement control, while the stainless steel bellows provide the flexibility required to absorb specified axial pipe movement.
For UAE and regional MEP projects, Kinetics Middle East provides engineering support for expansion-joint selection, piping restraint requirements, anchoring, guiding and project-specific technical requirements.

The SSEJ-250T-SG is used to accommodate dimensional changes in piping caused primarily by thermal expansion and contraction. Its stainless steel bellows provide controlled flexibility within a compact piping component.
Kinetics technical drawings list BSPP, BSPT and NPT threaded-end options for the SSEJ-250T-SG range. The exact connection should be specified when submitting the project requirement.
Published SSEJ-250T-SG technical drawings include 16 bar and 25 bar working-pressure configurations.
The published working-temperature range for the SSEJ-250T-SG is −50°C to +450°C, subject to correct engineering selection for the application.
Standard drawings provide ±25 mm axial movement. Kinetics also provides a separate 25 bar, ±50 mm axial-movement configuration.
The flexible bellows element is manufactured from SUS/SST304 stainless steel. The technical documentation also identifies an SST304 inner sleeve and carbon-steel structural/control components.
Anchors and guides control the piping movement and pressure forces acting on the expansion joint. Incorrect restraint can allow the joint to extend or buckle beyond its intended operating limits. Kinetics recommends engineering review of the anchoring and guiding arrangement before installation.

KINJOINT SSEJ-250T-SG stainless steel expansion joints are intended for piping systems where temperature changes create axial expansion or contraction that must be accommodated within the mechanical design.
Typical project applications include:
Expansion-joint selection must be coordinated with the system’s design pressure, temperature, movement requirement, connection type, pipe size, anchoring and guiding arrangement.

Compact thermal-movement control
The stainless steel bellows accommodate specified pipe movement within a compact assembly, reducing the space required compared with conventional pipe-loop arrangements where an expansion joint is appropriate.
Threaded connection options
BSPP, BSPT and NPT threaded-end configurations allow the product to be coordinated with different piping specifications and project requirements.
16 bar and 25 bar configurations
The SSEJ-250T-SG technical range includes working-pressure options suitable for different mechanical piping requirements.
High operating-temperature range
Published technical data covers working temperatures from −50°C to +450°C, subject to correct product selection and application review.
Controlled axial movement
Standard drawings provide ±25 mm axial movement, while a separate 25 bar configuration is available with ±50 mm axial movement.
Stainless steel bellows construction
SUS/SST304 bellows provide the flexible element of the expansion joint, supported by an SST304 inner sleeve and engineered structural components.
Tie/control rod configuration
The SG arrangement incorporates tie/control components to help protect the joint against movement beyond its intended operating condition when used as part of a correctly engineered piping system.
Project-specific options
Alternative materials, finishes, larger sizes, movement requirements and working pressures can be reviewed by Kinetics for project-specific requirements.
Correct anchoring and guiding are essential when installing metallic bellows expansion joints. The piping system must be engineered so that pressure thrust and pipe movement do not extend, compress or buckle the expansion joint beyond its allowable movement.
Control units must be used where required to protect the expansion joint from excessive movement when the piping system is not adequately restrained. Expansion joints should be selected using the actual pipe size, connection, movement, working pressure, operating temperature, piping layout and anchoring conditions.
Before final selection or installation, submit the project operating parameters and piping arrangement to Kinetics Middle East for technical review.
