Advantages of the
support rings Why are these rings so proven and why should they be used when laying pipes?
- The laying of the pipeline is facilitated. This is due to a reduction in the coefficient of friction, which means that damage to the coating of pipes will be prevented.
- Large selection of cross-sectional dimensions.
- High level of insulating qualities. The protection of the pipes is at the proper level.
- Extended service life of the pipeline.
Thus, using support rings on horizontal sections, we not only solve the problem of the junctions of the butt moments, but we also solve the problem of the safety of the pipe itself, which is of no small importance. This is especially true for long horizontal sections, where banal attraction will eventually create an emergency situation if the pipe is not additionally secured. In addition, such rings should have a full electrical insulation.
Support ring types
Let's consider the main types of support rings. Since the pipes are different, the rings can also differ in diameter, function, material and so on. Diameter indices are external.
- Plastic support ring.
The simplest. Suitable for outside diameter from 25 mm to 336. The kit usually contains nuts and bolts for installation. The product itself is made from two semirings. Simple installation. - Plastic ring of larger diameter. In general, the same as the first, with a difference in its diameter - from 98 mm to 385. Additional materials( bolts, nuts, fasteners) are usually sold in one set with the ring itself. It consists of two parts-semirings.
- Universal support ring.
All its charm is not only in simple installation, but also the complexity of the diameter. That is, this ring can be applied from 400 mm. This allows an external system of clamping ranges. - Such rings, as in the photo below, are used from 402 mm. You need to pay special attention to the edges of the ring - their height can be changed to the customer's choice.
- For pipes with high weights, diameter from 500 mm.
Mounting of support rings
Mounting support rings on horizontal sections is very simple and not as difficult as it might seem at first. Of the tools, we do not need anything non-standard. It is worth noting that each set has a separate table of sizes, which greatly simplifies the task of mounting. Do not forget one important fact - the pipe in the area of contact with the support ring must be treated with a protective tape. This will avoid such an unpleasant moment as slipping. In addition, the application of this tape increases the level of adhesion of the pipe and with the ring. You can buy it separately, but sometimes it comes bundled. In any case, it is better to clarify this issue at the time of purchase, in this situation, you can immediately pick up the necessary tape, if it is not included. The calculation of the mounting of support rings on different pipes is as follows:
- 2.5 mm for pipes up to 33 mm in diameter.
- 2.0 mm for pipes with a diameter of 400 to 600 mm.
- 1.5 mm for pipes with a diameter of more than 600 mm.
In other cases, the calculation takes place individually and you, most likely, can not do without the help of specialists, although in the field of advice and advice.
