What are the characteristics of threaded sleeve connection technology? Feel free to participate actively in the discussions – there are wealth rewards for everyone! ! !
1. High connection strength, with stable and reliable connection quality. The joint strength meets the requirements for Grade I joints as specified in the industry standard JGJ107-2010 \"General Technical Specifications for Mechanical Connection of Steel Bars\". The tensile strength of the joint shall be not less than the actual tensile strength of the connected steel bars, or 1.10 times the standard tensile strength of the steel bars. It has good anti-fatigue performance. The joint passes the 2 million-cycle fatigue strength test specified by industry standards ； Save materials; taking the steel bar coupling sleeve with a diameter of 40 mm as an example, the mass of the extruded sleeve is 4 kg, while that of the straight-threaded sleeve is 1.1 kg. The quality of straight-threaded sleeves is 25% that of extruded sleeves, yet their joint performance can compare to that of extruded joints. 2. Easy to construct and fast to connect. Factory-based processing of steel bar ends, without delaying the construction timeline ； On-site connection and assembly tasks take little time ； The processing of steel bar threads is simple; by loading the steel bar once, both the rib removal and thread rolling processes can be completed. This results in a fast processing speed and high precision in the formed threads. Reinforcement straight-thread sleeves have a wide range of applications ； There are no requirements regarding the weldability of the rebar; it is suitable for joining HRB335 and HRB400 rebars with diameters ranging from 14 to 50 mm, in both the same-diameter and different-diameter configurations, in any orientation. Technical features of the straight-thread steel bar sleeve connection method: 3. Environmentally friendly construction. The processing of steel bar ends and the on-site construction of joints generate no noise pollution, no open flames, and no dust, making them safe and reliable. Save energy ； The equipment has a power rating of only 3–4 kW, so no specialized power distribution facilities are required, nor is it necessary to install dedicated wiring. Good resistance to low temperatures ； Passed the -400°C low-temperature test. Construction 24/7. Not affected by weather conditions such as wind, rain, or snow.
