Purchase and installation, 7 points for attention of radiator

(Summary description)Radiator is an important and basic component in hot water (or steam) heating system. The hot water is cooled in the radiator (or the steam condenses in the radiator) to provide heat to the room to achieve the purpose of heating. The metal consumption and cost of radiator account for a considerable proportion in the heating system. Therefore, the correct selection of radiator involves the economic index and operation effect of the system. The following are seven precautions for radiator, selection and installation guide.

1. When the position of radiator hole is asymmetric, the size of asymmetric position shall be indicated.

2. When designing the radiator or electric heater with cover on the tube sheet or side plate, it is necessary to ensure that the hole position on the storage plate or side plate can be installed (i.e. there is enough distance between the side line of the cover and the tube plate to facilitate the installation, and the spacing is usually about 35 ~ 40mm).

3. The design pressure and temperature shall be indicated in the technical requirements of the drawing:

(1) When the heat sink is carbon steel and stainless steel, the design pressure is 1.0MPa and the design temperature is 350 ℃;

(2) When the heat pipe is carbon steel aluminum rolling pipe and stainless steel aluminum rolling pipe, the design pressure is 1.0 MPa and the design temperature is 250 ℃;

(3) In the surface cooler, the design pressure is determined according to the thickness of the copper tube (for example, the design pressure is 0.8MPa when the Φ 15.88x0.8mm copper pipe is used), and the design temperature is 100 ℃.

4. Attention should be paid to the interface position in the right view (whether the interface has enough welding position).

5. When the cleaning opening is more than 400X400, the folded edge shall be 35 ~ 40mm. When opening, the folded edge shall be folded outward.

6. When the diameter of the hood opening is greater than 800mm, the diameter change of the hood is 50mm.

7. If the hole of the customer's equipment is small and close to the edge, it is recommended that the customer enlarge the hole or punch the hole by himself.


8. Purchase guide - radiator selection should meet the following requirements:

(1) Good thermal performance.

(2) The pressure bearing capacity meets the requirements.

(3) The shape should be coordinated with the interior decoration, and its size should adapt to the building size and requirements.

(4) Easy to remove dust.

9. Installation guide

In most cases, the heat dissipation of the radiator is reduced after the cover is added. The radiator of the staircase should be arranged in the bottom layer and the lower layer as far as possible. But it can't be placed between two outer doors. The radiator arranged at the bottom floor of stairwell and other places with freezing danger shall be far away from the outer door.

The radiator can be surface mounted or concealed mounted. When surface mounted, it is easy to remove dust, simple layout and conducive to heat dissipation. For the civil and public buildings with high requirements for room decoration or places to prevent scalding or bumping, decorative covers can be added for concealed installation.
