What is the difference between pipe clamp and heavy pipe clamp!
U-shaped pipe clamp: the pipe clamp is used to fix the pipe (commonly known as saddle clamp) and is used for fixing the ground (note that it is not allowed to drill holes and fix the geothermal ground or where there are pipelines on the ground). The live line shall not go inside the gypsum line. The pipe before ground leveling shall also be fixed
pipe clamp:
1. Application scope of pipe clamp
Light series pipe clamps are used for ordinary mechanical pressure pipes of 6 size series, with an outer diameter of 6-57mm.
Double series pipe clamps are used for mechanical pressure pipes of 5 size series, with an outer diameter of 6-42mm.
Heavy series pipe clamps are used for high mechanical pressure pipes of 8 size series, with an outer diameter of 8-273mm.
2. Material characteristics of pipe clamp
Density, bending strength, impact toughness, compressive strength, elastic modulus, tensile strength, temperature resistance, color

3. Pipe clamp installation procedure
Before assembly on the welding plate, in order to better determine the direction of the clamp, it is recommended to mark the fixed position first, then weld, insert the lower half of the pipe clamp body, and place the pipe to be fixed. Then put on the other half of the pipe clamp body and the cover plate and tighten it with screws. Do not directly weld the bottom plate with pipe clamp installed.
Install the guide rail on the ground. The guide rail can be welded on the foundation or fixed with screws. Then push the guide rail nut into the rail and turn it 90 degrees. Insert the lower half of the pipe clamp body into the nut, put the pipe to be fixed, and then put the upper half of the pipe clamp body and cover plate, which are fixed with screws.
For stacking assembly, the guide rail can be welded on the foundation or fixed with screws. First install the upper and lower half of the pipe clamp body, put the pipe to be fixed, and then put the upper half of the pipe clamp body, fixed with screws, and prevent it from rotating through the anti loosening cover plate. Then install the two pipe clamps in the same way as above.
For the assembly of the elbow, the front and rear of the elbow shall be directly fixed with Castel pipe clamps. It is recommended that such support points should be fixed.
Therefore, there is no difference between pipe clamp and pipe clamp. Their uses are the same, but the product names are different. Some people call him pipe clamp and others call him pipe clamp.
