A straight threaded sleeve is a steel sleeve for a mechanical joint of steel bars that transmits axial tension or pressure of the steel bars. Straight thread sleeve is divided into direct rolling straight thread sleeve, stripping rib rolling straight thread sleeve and upsetting straight thread sleeve. The connection method of the straight thread sleeve is to peel off a part of the longitudinal rib and the transverse rib at the end of the steel bar to be connected by a thread rolling machine, then roll it directly into a common straight thread, and connect it with a special straight thread sleeve to form the connection of the steel bar.

China Steel Association: the recent steel market chasing up and down, the initiative steel enterprises to maintain a firm, to avoid stampede

The China Iron and Steel Association stated that the iron and steel industry is an important basic raw material industry and is vital to the healthy and stable development of the national economy. The high-quality development of the steel industry is the unity of quality and quantity, which is the last word. The national industrial structure determines the consumption structure, the consumption structure determines the variety structure, and the variety structure determines the production structure. Since the Spring Festival, the steel market has been declining rapidly, showing a "three high and three low" situation of high output, high cost, high inventory, low demand, low price and low efficiency. In the short term, the steel market fluctuates greatly, which is not conducive to the orderly and healthy development of the industry.
