Huhang C2F force transfer compensation joint consists of a flange loose sleeve compensation joint

The C2F force transfer compensation joint consists of a flange loose sleeve compensation joint, a short pipe flange, force transfer screws and other
components. It transmits the pressure thrust of the connected parts and compensates for pipeline installation errors, without absorbing axial displacement. It is a dedicated device mainly used for the loose sleeve connection with accessories such as pumps and valves.

Product Description

Features

Helps absorb axial forces generated at pipeline ends and blind flanged connections, reducing stress on the piping system.
Transfers pressure thrust from connected equipment to the pipeline support structure.
Allows for minor alignment differences during pipeline installation.
Provides flexibility for installing, servicing, or replacing pumps and valves.
Offers strong resistance to tension and compression, with reliable sealing performance.
Installing a force transmission joint near pump outlets and pipeline elbows helps distribute thrust and reduce the risk of impact damage to nearby pipes or equipment.

Precision Valve Manufacturing

Professional Valve Manufacturer | Integrated Manufacturing

Raw Material

We select high-quality raw materials according to product specifications and international standards. All incoming materials are carefully inspected to ensure chemical composition, mechanical properties and traceability.

Forging & Casting

Advanced forging and casting processes are used to produce strong and reliable valve bodies and components. Strict process control ensures uniform structure, dimensional accuracy and excellent mechanical performance.

CNC Machining

Our CNC machining equipment provides precise and consistent processing of valve components. Critical dimensions, threads and sealing surfaces are strictly controlled to ensure accurate assembly and reliable sealing performance.

Shot Blasting & Coating

Valve surfaces are professionally shot blasted to remove rust, scale and impurities. Protective coatings are then applied according to customer requirements, providing excellent corrosion resistance and a durable surface finish.

Pressure Testing

Every valve undergoes strict pressure testing before shipment. Body and seat tests are performed according to applicable standards and customer specifications to verify pressure resistance and sealing reliability.

Quality Inspection

Our quality control team conducts comprehensive inspections throughout the production process. Finished valves are checked for dimensions, appearance, materials, pressure performance and overall quality before final approval and shipment.

Ordering Information
Please specify the nominal diameter (DN), pressure rating (PN), flange standard, working medium, operating temperature and required quantity when sending an inquiry. If you have a drawing or special material requirements, please share them with us for confirmation.

FAQ

Q1: What is a force transmission joint used for?
It connects pipeline components while transferring pressure thrust to the supporting structure. It can also provide limited axial adjustment during installation.

Q2: Where is it commonly installed?
Typical locations include pump outlets, valve connections, and pipeline elbows. The installation position and support arrangement should be determined by the piping design.

Q3: Can it compensate for pipeline misalignment?
It can accommodate axial installation tolerances within its specified adjustment range. It is not intended to correct significant angular or lateral misalignment.

Q4: Does the joint eliminate the need for pipe supports or anchors?
No. Pipe supports and anchors must be designed to withstand the forces in the pipeline system.

Q5: What information is needed for a quotation?
Please provide the nominal diameter (DN), pressure rating (PN), flange standard, working medium, operating temperature, quantity, and any special material requirements. A drawing or project specification is also helpful.
