Radiator ms-140-500: characteristics, features, typical
In this article, we are to examine the cast-iron radiator of heating MS-140-500. We will get acquainted with its characteristics and find out in which heating systems its use is meaningful. In addition, we have to find out what problems can be expected from this device and how they can be solved.
What it is
Description
Under the name of the cast iron radiator MS-140M-500 (MS-140-500), a sectional battery of gray cast iron with cast-iron or steel connecting nipples and inter-section gaskets made of paronite is sold.
Product properties are quite common for cast-iron heaters:
- Considerable mass and, as a result, large thermal inertia;
- Solid capacity in terms of section, again increasing thermal inertia;
- Relative fragility (gray cast iron is not resistant to shock loads);
- Moderate resistance to internal pressure.
Fasteners are not included. Depending on the choice of brackets, the device can be mounted on the wall or mounted on the floor.
Specify: in 99% of cases, wall mounting is selected. For outdoor installations, products with a more attractive design are usually preferred. Let's be realistic: the cast iron radiator MS-140 M-500 is not amazed by the beauty and perfection of the lines.

Special features
So, what conclusions can be made by examining the technical characteristics of the cast iron radiator MS-140-500?
- Slow heating and equally slow cooling make the device an excellent choice for an autonomous system with a solid fuel boiler.. The inertia will smooth out fluctuations in the temperature of the coolant with infrequent kindling.
- Wide internal channels of sections and collectors, together with a large diameter connecting thread will allow it to be used in gravity systems. Thanks to the specified features, MS-140 will create minimal hydraulic resistance to flow.
- Despite the long-term use of this heater in central heating systems, the characteristics of the cast-iron radiator MS-140M-500 do not allow him to recommend it for this purpose with a light heart. The key word is water hammer: there can be 20 or 25 atmospheres at the front of the elevated pressure area that is not designed for the device. Yes, water hammer is a non-standard situation, but, believe the author’s experience, in the real world it is not uncommon.
Problems and Solutions
What problems can expect the owner of a cast iron battery?
Intersectional leaks
The reason for their occurrence is multiple cycles of heating and cooling (read - expansion and compression) during normal operation of the heating system. As a result, paronitic gaskets lose elasticity, and with the next cooling of the battery at the joints of the sections, moisture acts.
When a small leak through one or two gaskets instruction how to fix the leak looks like this:
- When the coolant is discharged, blind plugs are opened.
- On the radiator key, the distance to the problem nipple is measured.
- The key is slid into the collector until the coupling with the nipple is tightened with any lever or gas wrench No. 2 - No. 3.
Note: the thread on the deaf traffic jams - left. To tighten the nipple, rotate it counterclockwise.
If leaks become widespread, the radiator is moved with the replacement of all gaskets. In the role of the latter can be used as regular paronitovye products, and rubber, carved with their own hands from the car camera.
Lock on lock nut
Another problem with cast iron batteries is periodic leaks from under the lock nuts on the liner. The main reason is the burnout of sanitary flax at a high temperature of the heat carrier.
How to eliminate a leak:
- Shut off the heating riser (at the bottom filling - together with the riser double to it). Partially unscrew the vent plug to ensure that there is no overpressure. It is not necessary to discharge the water: it will blow the jumper on the top floor.
- Unscrew the locknut, increasing the gap between it and the stopper to 8-10 millimeters.
- Clean out the old reel.
- Tie the nut with sanitary flax with a small amount of any quick-drying paint or silicone sealant.
- Tighten the locknut. Start the heating riser.
Sometimes the cause of permanent leaks is the discrepancy between the axis of the thread of the lock nut perpendicular to its plane.
In this case, the only way to solve the problem is to replace this fitting:
- The riser is completely reset.
- The lock nut and radiator plug are turned in turn.
- The liner is removed from the radiator, after which the plug and locknut are unscrewed from the thread.
- Then all operations are performed in the reverse order, but with a new nut. For winding radiator plugs use the same flax with paint or sealant.
Conclusion
Despite its age, cast iron heating appliances are still in service and everything is the same as half a century ago, demanded by the market. The video in this article will help the reader to learn more about their features. Successes!
