   For fixing the main thermal insulation layer on devices and tanks, we have developed and improved existing structures made of single P1 and double P2 pins (GOST 17314-81), the production of which is carried out on automatic CNC lines made of wire steel with a diameter of 5 mm.
Fastening with pins is less labor-intensive and less expensive than with clamps and is used to isolate devices with a diameter of 500 mm, of various heights and lengths.

   The methods of fixing the insulation depend on whether welding is allowed on the insulation surface. If welding is possible, the pins are welded to the insulated surface or installed in pre-welded brackets C1 or bushings V1, and if it is impossible to carry out welding work, the pins are attached to tie bands using special brackets C2 fixed to the bandage with the help of exhaust rivets, or, use threaded pins SHR screwed into threaded rivets placed on the bandage.

   The thermal insulation material is impaled on the pins, after which the outer end of the pin must be bent at a distance of the insulation thickness. It is possible to use the attachment to the pin with a washer or a locking washer, which, when put on the pin, tightly press the thermal insulation layer to the insulated surface. When using a washer, the outer end of the pin is bent, and when using a locking washer, the excess part of it is cut off.

   Removable parts, suspension pins (single PS1, double PS2 or threaded PS), are installed at the installation site of thermal insulation in the following ways:
● Welded directly to the wall of the device or pipeline;
● Into bushings or staples previously welded to the wall of the device or pipeline;
● Into the brackets attached to the tie band with the help of exhaust rivets;
● Into the threaded rivets attached “on the tie band.

Types of pins used for fixing insulation, their placement on the surface depends on the thickness of the insulation.

* The dimensions of the pins are regulated according to GOST 17314-81.

The thickness of the thermal insulation layer: 60-250 mm.

The length of the pins is used in such a way that its length exceeds the thickness of the thermal insulation by 50 mm.

The number of pins required for mounting depends on the installation step of the pins and the location of the insulation surface.

The thermal insulation layers on the devices and tanks are fixed with pins, observing the following steps:
● On vertical sections, a step is set through 250 mm horizontally and 500 mm vertically.
● On horizontal lines in all directions through 500 mm, in the lower part along the circumference, the step is made equal to 250 mm, in the upper part along the circumference equal to 500 mm.
● On the bottoms of vertical and horizontal apparatuses and tanks with a diameter of more than 1 m, a step along the circumference through 250 mm, the diameter of the first circle is made 800 mm, each subsequent increases by 1000 mm.
