Pipeline bracket in life is very widely used, mainly used to support the pipeline, such as heating pipes, gas pipes, underground water pipes, etc., the bracket material is mainly based on steel and aluminum alloy, corrosion-resistant, easy to solid shape, support the heavyweight pipeline, do not look down on the bracket, but the maintenance and installation of pipelines plays an important role, said so much, what is the pipeline bracket? Material classification and what are the specifics, the next follow this article to learn it.
Basic Information
Used for the ground overhead laying pipeline support a structural member, supporting the pipeline and limit the pipeline deformation and displacement, to bear the pipeline from the internal pressure, external load and temperature deformation of the elastic force.
Divided into fixed bracket and activity bracket. Activity bracket is divided into sliding bracket, guide bracket, rolling bracket and suspension bracket.
Pipe supports are used wherever pipes are laid and are also known as pipe supports, pipe sections, etc. It serves as a support structure for the pipeline, and according to the operating performance and arrangement requirements of the pipeline, the pipe stand is divided into two kinds: fixed and movable. The place where a fixed point is set up becomes a fixed support, and this kind of pipe rack and pipe support cannot be displaced relatively, and the deformation of the fixed pipe rack after being stressed should be small compared with the deformation value of the pipe compensator, because the pipe rack should have sufficient rigidity. Set the intermediate support place using movable pipe rack, pipe and pipe rack is allowed to produce relative displacement between the pipeline, do not constrain the thermal deformation of the pipeline.
Classification
1, according to the load is divided into three grades: extra-light grade (Q), medium grade, extra-heavy grade (Z). In each load class, it contains four structure types: axial sliding, bi-directional sliding, guided sliding, and double guided sliding.
2. According to the material of the bracket, it can be divided into steel structure, reinforced concrete structure, brick and wood structure and so on.
3, according to the use can be divided into movable bracket (allow the pipe in the bracket displacement bracket) and fixed bracket (fixed in the pipe with the bracket). Fixed bracket used in the pipe does not allow axial displacement of the place, commonly used several fixed bracket as shown in the figure.
Active bracket is divided into sliding bracket, guided bracket and rolling bracket.
Installation methods
Pipe bracket installation methods:
1, planted and buried bracket installation
2, welded bracket installation
3, expansion bolts method bracket installation
4, hoop method bracket installation< /p>
5, nail method bracket installation
Construction requirements
National standard "building water supply and drainage and heating engineering construction quality acceptance specification" GB50242-2002 in the pipeline bracket has the following requirements:
Article 3.3.7? Piping support, hanging, bracket installation, shall comply with the following provisions:
1, the location of the correct, buried should be flat and firm;
2, fixed bracket contact with the pipe should be tight, fixed shadow firm;
3, sliding bracket should be flexible, sliding bracket and sliding groove on both sides of the gap should be left 3 to 5 millimeters, the longitudinal movement should be in line with the design requirements;
4, no heat Extension of the pipe hanger, boom should be installed vertically;
5, there is a thermal elongation of the pipe hanger, boom should be offset in the opposite direction of thermal expansion;
6, fixed to the building structure of the support, hanger shall not affect the safety of the structure
Through the introduction of product information on the pipeline bracket through the small, what are the classifications and so on have a greater understanding of the pipeline bracket, everyone in the understanding of what is the pipe Bracket, you can better utilize it, pipe bracket has waterproof, put the characteristics of corrosion, in the installation of easy to operate, if you need to use the pipe bracket for their own home improvement, you can refer to the introduction of the small, I hope to be able to help you, if you want to know more about the pipe bracket other information, please continue to pay attention to the Tubapu decoration network.
