Product Description:

U-shape is generally used in cargo vehicles, it is used to stabilise the chassis and frame of the vehicle. For example, the steel plate spring is U-bolt to connect.
U bolts are widely used, the main use: construction and installation, mechanical parts connection, vehicles and ships, bridges, tunnels and railways.

Main shapes: semi-circular, square right angle, triangle, oblique triangle, etc.

Applications

U-bolt heat tightening is suitable for what occasions

Thermal tightening is the internal control of the medium temperature requirements of the pipeline bolts, in addition to the construction of the fastening, the need to reach a constant temperature or different temperatures in a process of work and then the fastening. And in normal use, the temperature rises, the bolt is subjected to thermal expansion, the gap increases, the need to complete the sealing from zero by hot tightening operation....

In general, the requirements of the internal temperature > 200 ℃ in the equipment, pipelines, etc., need to bolt fastening heat tightening.

Hebei Wanxin Fastener Manufacturing Co., Ltd, the main production of products are: U bolts, steel bolts, ground bolts, flange, double-headed bolts, highways, railways, underground supporting fasteners, a variety of pre-embedded parts, high-strength bolts, high-strength hexagon, scaffolding, through the wire water-stop screws, high-strength nuts, through the wall wire reinforcing stirrups,, step by step, the top bracket, butyl threads, water-stopping steel plate and so on.

There are two main ways to judge the hardness of steel, which are Brinell hardness in HB and Rockwell hardness. Firstly, from the Brinell hardness, will be a hardness higher than the measured steel ball to the steel above, and apply a force F, then the ball will be in the measured steel will leave a dent, measured, the area of M, then Rockwell Brinell hardness will be F/M. Next Rockwell hardness is also convenient to explain the only difference between the latter and the former Rockwell hardness measurements is the force to force to divide by the depth of the small ball plunged into the.

Steel can be improved by mixing it with alloys, for example by adding carbon, known as carbon steel, which increases its hardness and rigidity but decreases its toughness and plasticity. By adding chromium, the hardness and rigidity of steel can be increased with less effect on its toughness. By adding titanium, the hardness and toughness of steel is increased.

The properties of steel can vary after different types of processing, with a focus on quenching and tempering, two of the earliest forms of steel processing that I learnt about as a child, both of which I learnt about through the game Ride and Slash. Firstly, quenching is the process of heating steel to over 723 degrees and then soaking it in water for a rapid cool down to increase the hardness and decrease the malleability of the steel. Tempering means heating the steel to over 723 degrees and then cooling it slowly to increase its strength and toughness at the same time.
