Quick Release Thermal Isolation for Pipelines

Thermal isolation works are the final stage in the construction process of any project, regarding the quality and easy installation of this product the project will be ready for operations on time and not only but also the quality of the objects produced will be higher,
economical and technical characteristics of the project will be in top level. In our work experience with thermal isolation systems, full factory readiness constructions are used, supplied from enterprises in the form of ready-made complex elements, consisting of thermal isolation and cover layers, equipped with a set of fasteners. At the same time the work goes from producing thermal isolation elements to installation of finished-ready elements on the isolated surface. It is widely used in energy, housing, communal services, chemical, oil refining, metallurgical, food and other industries.
Reducing noise and heat impact on the environment
Increase operational safety
Providing quick access to protected objects for technical repair and control
Reducing time of assembly and disassembly works

1. Heat isolating layer – basalt pierced fireproof mats.

2. End perforated protective coating QRTI

3. Ceramic fiber inserts

4. Bottom end perforated protective coating QRTI

5. Internal protective closure QRTI

6. Distance springs

1. The outer protective coating protects the main heat-isolation layer from mechanical damage,
humidification and exposure to aggressive environments. The higher heat-isolation ability of a structure, the higher its surface density. The external and internal coating of QRTI is made of stainless steel 12 * 18H 10T with a thickness of 0.8 mm

2. Handles are made of stainless steel 12 * 18H 10T 2mm thick. A stiffening rib along the entire length of the power protects the handle from deformation at the time of its operation. The height of the handle allows you to work with protective equipment (Safety comes first). The number of handles on the outer protective layer depends on the weight and length of the block QRTI.

3. The lock with adjustable tension L = 150-180 is a universal fastener, the feature of which allows you to reliably adjust the degree of bonding of two surfaces. The lock is distinguished by the possibility of adjusting the length of the screw, and with the correct selection of the required compression ratio, the lock becomes very resistant to vibration

4. The protective curtain is made of stainless steel 12*18H10T. Protects the entire structure of the QTRI from humidification and exposure to aggressive environments. The protective curtain is mounted on the QRTI unit using pulling rivets made of stainless steel.

To increase stiffness of the QRTI, perforated metal walls made of stainless steel 12 * 18H10T with a thickness of 0.8-1 mm are installed on the sides of the block. The perforated wall allows obtaining a sufficiently large heat absorption in any temperature range
Thermal isolation layer
The thickness of the heat-isolation mat layer made of super-thin basalt staple fabric before laying in the (QRTI) is formed given the fact of compaction ratio.

In case of multi-layer isolation, the thickness of the mat made of super-thin staple fabric determined separately for each layer before compaction.
When defining the thickness of the following thermal isolation layer, the thickness of the mat made of basalt super-thin staple fabric the previous layer thickness is taken as a guide.

Based on calculations, the thickness of the basalt super-thin staple fabric after compaction is usually taken in the range of 50-150 mm.

1. Maintains thermalfeature during operation

2. Maintains the structure at a level that provides the required thermal isolation, physical properties and a specified service life

3. Refers to the group of non-combustible materials (GOST 30244-94)
Distance Elements

Air gap, one of the types of insulating layers that reduce the thermal conductivity to the minimum

Thermal sporulation of a sealed air layer is defined as a sporting of the thermal conductivity of the air layer, since heat transfer through the gap at a temperature difference on the surfaces occurs mainly by convection and radiation.
The thermal resistance of the air gap occurs, in addition to heat transfer by thermal conductivity and convection in the air gap, also direct radiation between the surfaces limiting the air gap
The amount of heat transferred by thermal conduction is small, since the coefficient of thermal conductivity of air is small (0.026 вт/(м. С)
To ensure the thickness of the air gap block (QRTI), the unit is designed in such a way that there is no direct contact between (QRTI) and the insulated object, which provides excellent thermal insulation

1. Madeof 65g springsteel

2.Made in the form of a flat spring of a specially calculated and designed shape for full absorption of thermal expansion

3.Attached to the inner protection of the casing with stainless steel blind rivets

4.The number of springs on the inner cover depends on the weight and length of the block

When installing distance springs on the internal protection of the QRTI, thermal conductivity bridges are created.

2. Air gap
3. Isolated Equipment
4. Spring
5. CeramicFiber

To eliminate this effect on the distance springs, heat – absorbing protective elements made of ceramic material ALSIFLEX are installed.

ALSIFLEX fibers are light weight and flexible insulation material with high temperature resistance, low thermal conductivity and high chemical stability.

Uniform structure free of long fiber bonding material ensures high performance. ALSIFLEX complies with CT 1260 c and density of 130 kg/m3.

There are “thermal bridges” in all the connection areas of the block where increased heat losses
To reduce losses through "thermal bridges", additional heat-isolation inserts between the QRTI units.

Inserts made of Fiberfrax fireproof ceramic fiber
Incorporating metal alloy filaments (type MR) allows for maximum strength at elevated temperatures.

Fiberfrax fabric can be used up to 1250 ° C.
Protective curtains made of stainless steel 12X18H10T as an additional element in the QRTI design to reduce losses through "thermal bridges", as well as to increase the thermal protection at the end of the blocks.
