TECHNICAL CONDITIONS 25.99.29-007-61278130-2019; GOST 17314-8

The pins / Devices are installed on the rings of the coupling bandage (unloading device) (with a step of ≈250 mm), designed to maintain load distribution when installing protective shells in the thermal insulation of horizontal pipelines, complex structures, as well as tanks and cylindrical apparatuses in industrial and marine projects.
Protective shells should be based on support rings and elastic elements that comprehensively provide optimal load distribution for the entire structure as a whole, which contributes to reliability and extends the service life.
At a temperature of 350°C, the pins of the structure are made of heat-resistant steel and are attached to the ring of the tie band using brackets or bushings to compensate for thermal expansion and reduce the vibration transfer of the isolated object.

Pins / Devices are additionally equipped with appropriate additional products. For example: a bracket or sleeve for fixing thermal insulation, for holding and distributing the load of protective structures when used on horizontal and vertical pipelines.

*For additional staffing, it is necessary to refer to another order form. And also, you can ask for help from our manager or engineer.

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.

PIN INSTALLATION STEP (mm)

Pin installation location	The step direction is vertical	Step direction Horizontal
Vertical equipment	500	250
Horizontal cylindrical equipment ▲ Upper half	500	500
Horizontal cylindrical equipment ▼ Lower half	250	500
Horizontal surfaces ▲ From above	500	500
Horizontal surfaces ▼ From below	250	500

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.

To preserve and improve the efficiency of the thermal insulation characteristics of thermal insulation, special support and unloading structures have been developed, using distance holders (legs with springs) and pins, the production of which takes place on automatic European CNC lines.

Pins on the rings of tie bands are used to prevent vertical displacement (sliding) of protective coatings on vertical pipelines and apparatuses when using soft thermal insulation materials.
All structures are made of carbon or stainless steel and are rings with intermediate support posts made of carbon or stainless steel, located at a certain distance. When using a bracket made of band steel (recommended choice!), which is attached to the ring of the tie band (unloading device) with exhaust rivets, in order to reduce heat transfer, the racks are separated from the ring of the tie band by heat-insulating gaskets. Installation to the pipeline is carried out by means of a bolted connection.

The wide application and popularity of support rings are due to their universal properties in application, quick and easy installation. It is an economical and eco-friendly material, resistant to aggressive environments, acids and oils, has a high fire resistance.
The pins on the rings of the tie bands are made of carbon or stainless steel, which have been tested by time and the Russian climate, which is characterized by sharp temperature changes and high humidity. They have successfully proven themselves in the thermal insulation of cold and hot water supply pipelines used in various construction and administrative complexes, industrial enterprises, medical and educational institutions, food industries, sports facilities and high-rise buildings.

The pins on the rings of the tie bands significantly facilitate installation during the assembly of thermal insulation, shells and ready-made prefabricated structures, which significantly extends their service life. It also serves as a reliable additional protection, helping the thermal insulation to withstand excessive mechanical influences and helps to avoid unwanted damage during operation or installation.

Installation conditions:
When using devices with pins for fixing thermal insulation, it is necessary to control the tightness of the insulation layer to the pipeline and the accuracy of the coupling of the elements of the insulation layer, as well as the metal coating.
A necessary condition for installation-the work should be carried out in dry weather to avoid precipitation in the form of moisture or condensate on the surface of the insulation.
