01. What are the cutting quality requirements for seismic supports and hangers?

What are the product quality standards for making seismic supports and hangers? The anti-seismic support is made by hand and automatically positioned. When laser cutting, the slag and splashes should be removed, and the laser cutting quality should meet the following requirements:

1. The unevenness of the inner hole of the wound shall not exceed 10% of the thickness of the steel part, and shall not exceed 2mm;

2. The supports and hangers shall be made according to the provisions of the design scheme, and the specification error of their assembly shall not exceed 3mm;

3. The error between the laser cutting line and the marking line for manual laser cutting shall not exceed 2mm, and the automatic positioning laser cutting shall not exceed 1.5mm;

4. After dragging or overturning the supports and hangers until production and processing, safeguard measures should be taken to avoid scratching or damage;

5. The snap ring of the pipe support and hanger is made of flat steel. The arc part should be smooth and symmetrical, and the specification should be consistent with the diameter of the water pipe;

6. The fillet weld of the pipe support frame and support shall be filled with flesh and excessively smooth, and the height width ratio of the weld leg shall not be less than 1.5 times the thickness of the thin member. Correct the welding deformation of electric welding;

7. Make qualified supports and hangers, which are coated with anti-corrosion paint and road markings, and stored properly. Carbon steel supports and supports need to be marked with relative raw materials and stored independently;

8. The anchor bolt holes of anti-seismic supports and hangers shall be produced and processed by planer or hand drill. Acetylene gas flame shall not be used to cut the holes. The production and processing error of the holes shall not exceed its random dimensional tolerance.


02. What are the names of common accessories of seismic support?

The names of common accessories of seismic support mainly include:

P-type pipe clamp, channel steel, connector, channel steel base, car repair anchor bolt, screw rod, stiffening device, hinge, Ohm type pipe clamp, suspension pipe clamp.

At present, there are many manufacturers of seismic support in the sales market. In fact, the cost of selecting accessories is only a reference level. It is important to see the quality of seismic support accessories.

03. What are the methods to reduce vibration of seismic support?

During the use of the seismic support, the stability of different steel links can be controlled. The movement of the finished seismic support in different positions can affect the resistance of the support, so as to prevent the seismic support from losing its seismic capacity after long-term use. Reducing the vibration of seismic support can also prolong its service life. This paper introduces the methods of reducing vibration.

In order to reduce the vibration of the anti-seismic support, we can improve the design, add the power of saving installation to the design strength of different moving directions, improve the moving obstacles caused by the floor resistance, reduce the rotation and inclination of the exhaust, and increase the firmness of the exhaust pipe.

Users can also reduce the vibration of the support by reducing the pressure friction. Reducing the pressure friction can avoid the phenomenon of high expansion of the water level of the strength, and can be used to adjust the problems of high use strength of different steel support frames and difficult operation of swing vibration.

When in use, users can also vent the strength rotation of the support frame, which can improve the strong support frame of the finished products of different air jet rotation processes, and reduce the stress wear degree of the seismic support.
