KINJOINT SSEL is a stainless steel braided flexible expansion loop designed to absorb thermal movement in gas, steam, water and chemical piping systems. The compact hose-and-braid loop reduces the space required compared with conventional hard-pipe loops, lowers loads transferred to pipe anchors and accommodates movement in multiple directions. Kinetics SSEL expansion loops are rated for 16 bar working pressure and temperatures from −50°C to +450°C, with ±40 mm and ±100 mm movement options and welded, threaded, grooved or flanged end connections.
Engineered for Performance.
KINJOINT SSEL is an engineered stainless steel flexible expansion loop for piping systems requiring controlled accommodation of thermal expansion, contraction and multidirectional pipe movement.
Unlike a conventional hard-pipe expansion loop fabricated from long lengths of rigid pipe and elbows, the SSEL uses flexible stainless steel hose and external stainless steel braid arranged in a compact loop configuration. This allows the assembly to absorb piping movement while occupying less installation space and imposing lower loads on the piping system.
KINJOINT SSEL expansion loops are suitable for consultants, MEP contractors, mechanical contractors, piping engineers and industrial project teams working on UAE, GCC and MENA projects where thermal movement must be incorporated into the piping-system design.

Thermal changes cause piping to expand and contract. When this movement is restrained, additional stresses and loads can be transferred into the pipework, supports, anchors, fittings and connected equipment.
The KINJOINT SSEL uses two flexible stainless steel braided hose legs connected through a 180° return. The flexible hose-and-braid construction allows the loop to deflect as the connected piping moves.
Because the flexible legs are arranged perpendicular to the main pipeline, the assembly can accommodate movement while reducing the amount of rigid piping required for a conventional fabricated expansion loop.
The result is a compact engineered method of managing thermal piping movement while reducing strain and anchoring loads within a correctly designed piping system.
KINJOINT SSEL stainless steel expansion loops are designed for thermal-expansion applications in:
Final selection must be based on the actual pipe size, operating pressure, operating temperature, required movement, end connection, media and piping-layout conditions.
KINJOINT SSEL occupies less installation space than a conventional rigid pipe loop, making it particularly useful where plantroom, riser, ceiling or service-space dimensions are restricted.
The flexible stainless steel hose-and-braid arrangement produces lower reaction forces than a conventional rigid expansion loop and can reduce loads transferred into piping anchors and related structural elements.
The flexible loop configuration can absorb movement in multiple directions rather than being limited to a single rigid pipe axis.
Two published movement capacities allow engineers to select an SSEL configuration according to calculated piping movement requirements.
The standard KINJOINT SSEL range has a published working-pressure rating of 16 bar.
The published operating-temperature range is −50°C to +450°C, supporting demanding hot and cold piping applications subject to correct engineering selection.
The flexible sections use stainless steel hose with stainless steel external braid to provide movement capability while restraining the hose under internal pressure.
Welded, threaded, grooved and flanged versions allow the SSEL range to be coordinated with different piping specifications and installation methods.
Depending on connection type, KINJOINT SSEL models cover nominal pipe sizes from DN15 through DN450.
Alternative construction materials can be reviewed by Kinetics where required by the process medium, project specification or environmental conditions.
Use SSEL-W where welded-end connections are required.
Use SSEL-T where threaded connections are specified.
Use SSEL-G where grooved-end piping connections are required.
Use SSEL-F where flanged connections are required.
After selecting the end connection, confirm the nominal pipe diameter and determine whether ±40 mm or ±100 mm movement is required from the piping thermal-expansion calculation.
For project selection, submit the pipe size, operating and design temperature, working pressure, media, calculated movement, connection type, piping layout and project specification to Kinetics Middle East.
Install the KINJOINT SSEL according to the approved Kinetics technical drawing and the piping-system design.
The flexible braided hose legs must remain free to flex through the movement for which the expansion loop was selected. Do not introduce torsional twisting, mechanical damage or installation forces into the stainless steel hose or braid.
Confirm that the selected model, movement capacity, pipe size and connection type match the approved project submittal before installation.
Where the 180° return requires support, the support arrangement must prevent excessive sagging without restraining the movement required for the loop to function.
Maintain the required piping anchor, guide and support arrangement defined by the piping engineer or approved piping-stress analysis.
Do not exceed the published 16 bar working pressure, −50°C to +450°C working-temperature range or specified ±40 mm / ±100 mm movement capability.
The SSEL drawing incorporates provision for an air-release or drain loop at the 180° return. The final orientation and drainage or venting arrangement must suit the piping medium and approved installation configuration.
Inspect the hose, braid, fittings and end connections for damage before commissioning.
Traditional hard-pipe loops use additional rigid pipe and elbows to provide enough flexibility for thermal growth. As movement requirements increase, these fabricated loops can occupy significant space.
KINJOINT SSEL uses corrugated stainless steel flexible hose and braid to provide the required flexibility within a more compact assembly. This allows the loop to absorb thermal movement while exerting less strain on the connected piping and reducing anchoring loads.
