Overview

It is suitable for plastic pipe clamps for pipeline fixing with oil, water and gas as the medium. The working temperature of dry thin oil lubrication is -5 ～ + 100 ℃. A series pipe clamps are suitable for fixing medium and low pressure (P N≤8M P a) pipelines; B series pipe clamps and B series type I combined installation pipe clamps are suitable for fixing medium and high pressure and high pressure (P N≤31.5MPa) pipes.

Dimensions

b) Size calculation H = H2 + H3 + (N-1) · T

In the formula: N —— number of pipes:

T-distance between adjacent pipes (see Table 3), mm;

H2, H3 see Table 2 and Table 3

◎ Note: The weight of each group of combined installation pipe clamps can be approximately (N-0.5) multiplied by the weight of the single piece in Table 2.

Pipe clamp bearing capacity

(A1, A2 and Figure A1, Figure A2)

A1 method of expression: the ability of the pipe clamp to withstand the axial force of the pipe is represented by a curve diagram.

A2 Details: Figure A1 is used for "A series pipe clamp"; Figure A2 is used for "B series Ⅰ pipe clamp". a curve indicates that the pipe clamp and the pipe are in "static friction"

State ", the diameter of the pipe is a function of the axial force of the pipe clamp. The b curve shows the pipe outer diameter when the clamp and the pipe are in a" dynamic friction state "

It is a function of the axial force and torque of the pipe clamp.

Four, installation instructions (B1 ~ B3)

The bottom plate of B1 pipe clamp is fixed on the welding plate, steel beam and track by welding. Attention should be paid to welding plates, steel

Beams and rails must be fixed securely. The load they receive must be within the allowable range (refer to Figures A1 and A2).

When installing B2, the distance between adjacent pipe clamps should be kept at a distance of 1-3m.

When B3 pipeline is installed, the pipe clamp should be installed after the curved part of the bend. (See Figure B1)
