Large diameter reciprocating swing rotary joint

The reciprocating rotary joint, also known as the swing rotary joint, is a movable switch specifically used for guiding fluid media between rigid pipelines. It is directly supported by balls inside, with flexible rotation and strong support capacity. The raceway has good wear resistance and a long service life; Solve the problem of fluid transportation where traditional hard pipes cannot move with the equipment. The product adopts a modular structure with large flange diameter, excellent pressure resistance, and supports free combination of multiple configurations. It can be customized according to working conditions and can adapt to harsh environments such as outdoor, high salt spray in the ocean, and flammable and explosive petrochemical environments. It is widely matched with various industrial equipment and process pipelines, and can transport various media such as water, steam, thermal oil, hydraulic oil, and various gases. Widely used in industries such as metallurgy, petrochemicals, road construction, shipbuilding, rubber, etc

1、 Application in the field of ship deck equipment
In the complete set of equipment on the ship deck, the large-diameter reciprocating swing rotary joint is a key movable connection for the deck fluid pipeline. During the operation of the ship, the deck pipeline will experience reciprocating oscillation and angular displacement accompanied by winches, cranes, and deck actuators. This rotary joint can absorb the oscillation displacement of the pipeline, avoiding the pulling, twisting, and cracking of the hard pipe.
It can be equipped with ship deck winches, offshore operation platform pipelines, ship loading and unloading pipelines, and offshore floating equipment fluid circuits to achieve continuous transportation of hydraulic media, cooling water, compressed air, and steam media, adapt to offshore salt spray, humidity, and impact vibration conditions, and ensure stable pipeline sealing during ship equipment swing operations.

2、 Application in LNG and Low Temperature Fluid Industry
For the fluid systems related to LNG receiving stations and LNG tanker loading and unloading, the large-diameter reciprocating swing rotary joint can be used for low-temperature fluid loading and unloading pipeline circuits, suitable for low-temperature medium transportation scenarios.
It can be assembled on LNG loading and unloading arms, low-temperature crane tubes, BOG evaporation gas recovery pipelines, and low-temperature storage tank supporting pipelines, allowing the loading and unloading arms to perform reciprocating swing alignment, compensating for equipment displacement, solving the torque and deformation caused by pipeline thermal expansion and contraction under low-temperature conditions, ensuring the safe transportation of low-temperature gases and low-temperature liquid media, and meeting the fluid pipeline connection needs of receiving stations and gas stations.
3、 Application of oil storage and fluid loading and unloading crane equipment
In the oil storage and transportation industry, various types of loading and unloading cranes and fluid loading and unloading arms need to frequently swing to align with tank trucks and storage tanks. The large-diameter reciprocating swing rotary joint serves as the core rotating component of the crane pipe, achieving flexible swinging of the loading and unloading arm and replacing traditional hose connection methods.
It can be used for oil loading and unloading cranes, coil machines, coil equipment, and floating pipelines in oil storage tank areas. It is suitable for transporting crude oil, refined oil, and chemical oil products, eliminating pipeline torque and avoiding pipeline distortion fatigue. It is suitable for oil depots, gantry loading systems, and process pipelines in storage and transportation tank areas, meeting the requirements of high flow oil transportation conditions.
4、 Application of winch, winch and coil unit equipment

During the process of retracting and unwinding pipelines using winches, winches, and coil units, the pipelines will continue to oscillate and deflect back and forth. The large-diameter reciprocating swivel joint can serve as the core component of the equipment body, matching the action of retracting and unwinding the coiled pipes.
It can be matched with hydraulic winches, cable winches, fluid coil units, and hose reel equipment. When the reel is wound back and forth in the pipeline, it continuously conducts hydraulic oil, cooling water, compressed air and other media. While the reel swings and rotates, the medium path is not interrupted, and the seal is not affected by the reciprocating swing action. It is widely used in industrial pipe winding equipment, lifting winches, and hose winding devices.

5、 Application in the Chemical Process Pipeline Industry
In chemical production process pipelines, many complete sets of equipment will have periodic swinging and deflection displacement, and direct connection of hard pipes is prone to stress damage and leakage risks. The large diameter reciprocating swing rotary joint can be used as a process pipeline activity compensation unit.
Suitable for chemical swing equipment pipelines, reaction device auxiliary pipelines, chemical transportation pipelines, and can transport various media such as water, steam, thermal oil, hydraulic oil, process gases, etc., to cope with high temperatures, corrosion, and outdoor environments in chemical plants, absorb pipeline displacement and torque caused by equipment operation, protect the entire pipeline and process equipment, reduce pipeline fatigue damage, and extend the service life of the entire pipeline equipment.
