The threaded joints adopt a threaded sealing structure, consisting of a pipe nut, a tapered cavity and a sealing ring with a blade. The thread strength is improved by cold working hardening process, and the tensile performance exceeds the standard of the base material. It is compatible with BSP internal and external thread connection, supports 3/8"-4" size, and can withstand PN10 working pressure. The core design includes prefabrication, safe construction without electricity or fire, and adaptability to operation in dense and narrow spaces. It can connect HRB335/400 grade steel bars of different directions and diameters. The ring blade reinforcement of the sealing ring adopts a 45°-90° bevel design. During assembly, an anti-counterfeiting indentation is formed by a transfer element to achieve quality traceability [1]. Some models have NPT standard external threads and adopt a 45-degree tapered structure to achieve self-sealing. They are suitable for low-pressure systems with pressure below 1000psi.
Features of threaded joints:
1. High joint strength and good ductility, fully utilizing the strength and ductility of the reinforcing steel base material. The joint performance meets the Class I joint standard in JGJ107-2003 and can break at the base material.
2. Convenient, quick, and simple connection.
3. Convenient and intuitive inspection.
4. Straight threads on reinforcing steel can be prefabricated, and sleeves can be factory-produced, saving time and increasing processing efficiency.
5. No electricity, gas, open flame, oil leakage, or pollution is required during construction; construction can be carried out in all weather conditions.
6. Strong applicability; can be operated flexibly even in confined spaces with densely packed reinforcing steel.
7. Can connect horizontal, vertical, and diagonal HRB335 and HRB400 grade reinforcing steel of the same or different diameters.

Advantages and Disadvantages of Threaded Joints
Threaded joints, as a common pipe connection method, have the following advantages and disadvantages:
Advantages:
1. Easy installation: No special tools or equipment are required; simple tools such as wrenches can be used to complete the connection.
2. Reliable connection: The threaded structure provides a strong tightening force between the connectors, capable of withstanding significant pressure and torque.
3. Wide applicability: Threaded joints can be used for various pipe connections, including liquid, gaseous, and solid media.
Disadvantages:
1. Not suitable for high-temperature and high-pressure environments: Threaded joints are prone to leakage under high temperature and pressure conditions.
2. Susceptible to damage: The threads and sealing surfaces of threaded joints are easily damaged, affecting the reliability and sealing performance of the connection.
