How to install spring support and hanger?

The scale of the spring indicates the displacement of the piping system. The spring itself has a pin that cannot be pulled out during the hydraulic test. After the hydraulic test is completed, it is pulled out and the spring is put into use.

The spring has been loaded according to the design requirements and locked with a pin when it leaves the factory. Do not pull out the pin during installation. Pull out the pin again when it is put into use. The amount of spring loading is determined based on operating temperature, load and displacement direction.

The spring support and hanger is made according to the design parameters provided by the design institute； When installing, install it as an ordinary pipe fitting equipment, without pre-tensioning or pre-pressure. When the device is put into use after the hydraulic test, just pull out the spring pin.

The spring supports and hangers have been tested in accordance with the requirements when they leave the factory. When installing, just remove the pins, support equipment and suspension equipment.

There is an article on the Internet that says this: (1) According to the installation load provided by the user, the manufacturer uses the upper and lower positioning blocks to fix the indicator plate of the spring support and hanger at the position corresponding to the installation load, so that the spring support and hanger is temporarily in a rigid state. (2) After the pipeline has been cleaned and hydraulically tested, the upper and lower positioning blocks must be removed before the pipeline can be put into use. (3) When the pipeline starts running, first check whether the positioning block has been removed and then check whether there is any jamming during the displacement of the indicator plate from the installation load to the working load. (4) After the pipeline is put into normal operation, check whether the displacement of the spring support and hanger under working load is consistent with the design. After the pipeline stops running, check whether the indicator plate is reset to the position where the load is installed.

Haha, be sure to pay attention to the above mentioned "When the pipeline starts running, first check whether the positioning blocks are all removed." I have encountered this before when driving, and some owners forgot to pull out the pins. . . . . . . . Fortunately, I found it in time before driving.
