The steel bar straight thread connection scheme is to strip off a part of the longitudinal and transverse ribs at the end of the steel bar to be connected using a steel bar thread rolling machine, and then roll them directly into ordinary straight threads, which are connected with corresponding straight thread sleeves to form the connection of the steel bars.

1. The main raw material should be 45 # steel that has undergone annealing treatment
2. The appearance of the sleeve can be a machined surface or a natural surface of the material, without visible large patches of embroidery, cracks, or other defects to the naked eye.
3.The size specifications of the sleeve should comply with the JGT163-2013 standard dimensions and tolerance range.
4. The thread should be inspected with a specialized gauge, and the thread accuracy should meet 6H.

Jiangsu Zhongdong CNPOW ®  The straight threaded sleeve products are made of high-quality 45 # steel and high-quality alloy steel, with reasonable design, advanced technology, high dimensional accuracy, and reliable connection quality. The basic parameters of each specification sleeve are designed according to the strength requirements of HRB500 grade steel bars, and are applicable to HRB400, HRB500, and HRB630 grade threaded steel. The performance indicators have been tested by the "National Construction Engineering Quality Supervision and Inspection Center" and meet the requirements of "I" grade joints in JGJ107-2016.

Jiangsu Zhongdong has been focusing on the industry for more than 20 years. Based on relevant technological advantages in the industry, the company has independently developed a complete set of professional production equipment for straight threaded sleeves, including DKG series pipe cutting machines, DBC series external turning chamfering machines, DDG series double head chamfering machines, DGS series fully automatic double axis tapping machines, etc. The fourth generation DGS series fully automatic dual axis tapping machine is highly praised in the market due to its high degree of automation, high production efficiency, and high precision in machining threads.
A special sleeve, called a weldable sleeve, is used in construction for special applications such as steel structures, steel beams, steel columns, and steel plates. It is welded to the sleeve and connected to a straight threaded joint at the other end. The intermediate weldable sleeve uses annealed raw materials to produce high-quality steel sleeves with good toughness and passing tensile tests. During use, there will be no twisting or breakage, ensuring high requirements and high standards for engineering construction. Features: 1. Complete specifications: The mid-range weldable sleeve M16-M32mm has complete specifications, and customized specifications can reach M12-M50mm.
2. Heat treatment process: All types of steel sleeves produced by Zhongdong Machinery are made of annealed raw materials. The produced steel sleeves have high quality, good toughness, and pass the tensile test. There will be no twisting, cracking, or breakage during use, ensuring high requirements and high standards for engineering construction. 3. Good performance: High quality alloy steel has good comprehensive mechanical properties, good low-temperature performance, good plasticity and weldability, and can be used as structures and building structures that bear dynamic loads such as power stations and bridges. It can be used in hot rolling or normalizing states and can be used for various structures in cold regions below -40 ºC. 4. Reliable quality: no bad teeth, consistent thread diameter, easy assembly, stable and reliable connection quality. 5. Stable supply: daily production of 100000+
