45# Carbon Steel Reinforcing Bar Mechanical Parallel Coupler
product description:
【product material]: high-quality 45 carbon structural steel.
【Product use】: It is used to connect two steel bars that have been processed into straight threads.
【Appearance】: The thread profile is full, there is no crack on the surface of the connecting sleeve, and there is no serious corrosion and other visible defects on the surface and inner thread. Use the thread plug gauge to check the internal thread, and the plug gauge can pass through smoothly.
Straight thread sleeve connection is a kind of sleeve connection.
Upsetting straight thread joint: the joint formed by the straight
thread made after the end of the steel bar is thickened and the
thread of the connector.
Rolled straight thread joint: a joint formed by direct rolling of
the steel bar end or rolling after stripping and rolling with the
thread of the connecting piece.
Stripped rib rolling straight thread connection is a new technology that has developed rapidly and has been widely used in recent years. It has many advantages such as simple construction, high efficiency, and stable quality. High, good fatigue resistance. It has all the advantages of upsetting straight threads, and avoids the brittle fracture phenomenon of upsetting straight threads. It is a mechanical connection technology for steel bars currently used.

This is new generation coonection type for rebar, tensile strength can reach 110% of parent rebar, and the sleeve is made of 45# carbon steel, with excellent quality and abrasion resistant.
First, use GD-150 Upset forging machine to enlarge the end of rebar.
Secong, use AGS-40C Threading machine to process screw on the enlarged end.
