Steel bar straight thread sleeve is a steel sleeve used for mechanical joints of steel bars to transmit axial tension or pressure of steel bars. Straight thread sleeves are divided into direct rolling straight thread sleeves, rib stripping rolling straight thread sleeves, and upsetting straight thread sleeves. The technology of steel bar rib stripping and rolling straight thread connection is a pioneering technological invention both domestically and internationally, reaching the international advanced level; The efficient, convenient, and fast construction method of rib stripping and rolling straight thread connection technology, as well as the advantages of energy saving, efficiency improvement, stable and reliable connection quality, have been favored by a large number of construction units and owners. It is a new type of product using straight thread connection technology.

According to the basic usage conditions of steel bar straight thread sleeves, commonly used sleeve models are divided into standard type, reducing type, positive and negative thread type, expansion type, reducing positive and negative thread type, and locking nut type. Special types of sleeves should meet relevant design requirements.

Scope of application: Steel bar connection sleeves for construction sites, bridges, subways, etc

。

Production process of steel bar straight thread sleeve:

Firstly, select the corresponding raw materials and use a two-stage annealing process to ensure high stability of the raw materials and good elongation of the sleeve for cutting

2. After sawing the material, perform appearance treatment (using the natural color of the raw material), peeling and chamfering

3. After the appearance treatment is completed, the most critical step is tapping

After threading the straight threaded steel bar sleeve, it is necessary to print anti-counterfeiting labels on the sleeve

After the manufacturer marks it, the next step is to package the product, which must be neatly stacked

6. We have our own testing equipment for straight threaded steel bar connection sleeves. Each batch of incoming raw materials and produced sleeves is tested in batches, and the packaging is labeled according to the different production teams and testing personnel of the corresponding batches. Once the sleeves we provide to you have quality problems, they can be traced back to the workshop manager and production team based on the batch number information, and the company will hold them accountable accordingly.

7. Basically, our company has stock of all specifications of steel bar straight thread connection sleeves. You only need to place an order before 3:00 pm, and we can guarantee same day shipment (except for special customized products).

Several benefits of using steel bar straight thread sleeves in the construction industry:

1. The use of steel reinforcement connection sleeves in the construction industry can greatly reduce the use of materials and is easy to operate, without being limited by the type of steel reinforcement composition. Can be prefabricated in advance, does not occupy the construction period, and has high processing efficiency.

2. The straight threaded sleeve has the advantages of convenient, fast, and simple connection, no need for electricity during construction, no wind or rain resistance, and can be used for all-weather construction.

3. Can connect HRB335 and HRB400 steel bars of the same or different diameters in horizontal, vertical, and diagonal directions.

The characteristics of the steel bar straight thread sleeve produced by our factory are:

Adequate stock, national standard testing, anti-counterfeiting steel seal, and full thread.
