How to weld the oven for a bath from a pipe

A simple and at the same time effective oven for a bath can be made independently from a conventional metal pipe with a diameter of 0.5-0.6 m. For such a furnace, a minimum of time and material is needed, while it is capable of heating a bath up to 20 cubic meters. The oven for a bath from a pipe has the simplest design and can be vertical or horizontal execution. To the merits of such stoves, it is possible to include the minimum of welded seams, and hence increased reliability, since the kilns are burnt most often in the places of welding.

oven The recommended wall thickness is 8 mm or more. In addition to the pipe, you will need sheet iron, a chimney with a diameter of 120-150 mm, trimming of the fittings, as well as a welding machine and a Bulgarian.

Vertical kiln from

pipe For such a stove, pipe lengths of 0.9-1 m and 0.5-0.6 m are required. The technology of making a vertical kiln from a pipe is quite simple.

1. Prepare the formwork for the foundation. The width of the form is equal to the diameter of the pipe plus 0.5 m. Lay the reinforcement and pour concrete. The thickness of the foundation should be at least 20 cm. After solidification of concrete, lay the floor with a brick or paving slab.
2. Align the bottom edge of a long piece of pipe - this will be the base of the oven, and it should stand exactly. Cut out on one side of the scoop with dimensions of 5x20 cm. At the same time, the scoop will play the role of an ash pan.
3. Over the ashtray, the bottom of the firebox is attached by welding. To do this, cut a sheet of metal with a thickness of at least 12 mm around the diameter of the pipe, in the center of it a hole is cut for the grate. The grate can be bought in a shop or made independently, having welded on the cut out a hole a steel rod in the form of a lattice, leaving the gaps equal to the diameter of the rod.
4. Cut out the window for firebox size 25x30 cm, the distance from the bottom of the furnace - about 5 cm Weld the hinges and fix the door on it. If there is a need to take the furnace into the next room, you can also weld an apron of rectangular shape around the door, retreating from it 5-10 cm from all sides.
5. The cutter is made above the furnace - a rectangular metal sheet with cut corners, behind which the sheet is welded to the pipe. Between the sides of the cutter and the pipe there are gaps sufficient for the passage of smoke. Thus, the circulation of smoke flows along the walls is created, which contributes to their heating.
6. At 5-10 cm above the cut-off, a grating made of a metal rod with a diameter of 12-16 mm is welded to the walls of the pipe. This will be the bottom of the heater. The heater door is positioned so that it is convenient to open from the side of the steam room. The door is made in the same way as the furnace one.
7. The top of the stove is brewed with a metal sheet with a hole, the diameter of which is equal to the diameter of the chimney. On the upper edge of the stove, you can weld the stops for the tank if the tank is removable.
8. The water tank can be made from trimming the same pipe or stainless steel. The bottom of the tank should exactly repeat the top of the heater. The pipe is welded to the bottom - it must pass through the center of the tank and go beyond its upper limits by 20-30 cm. The top of the tank is equipped with a removable cover in the form of a semicircle. In the lower part of it the crane is cut. The tank is installed on the stove and welded.

Horizontal oven from a pipe

A horizontal oven is made with an external heater and a hinged tank. The horizontal kiln is compact, and also has an increased depth of the furnace, which allows the bath to be heated quickly. The door of the furnace can be taken out into the waiting room - this will create additional convenience for the kindling of the bath.

pipe Horizontal manufacturing technology:

1. Cut a piece of pipe with a diameter of 0.5 m and a length of 0.8 m. Align the edges.
2. Make a grate pad: a rectangle with dimensions of 40x80 cm is cut from a sheet of metal 10-12 mm thick, a hole is cut into it and a bar or bar welded to it, or an industrial grate is installed.
3. Weld the grate pad inside the pipe. At the same time, the furnace casing is installed so that the welded pipe seam appears under the grate - as the iron burns more often in the welding area, this method reduces the thermal load on the seam.
4. Execute the front of the stove from sheet metal. The shape of the facade is a rectangle with a rounded upper part, with a width of 60 cm and a height of 70 cm. In the facade, two rectangular openings are cut out - for the furnace door and for the ashbox.
5. Perform the back of the oven in the form of a rectangle made of sheet metal with dimensions of 70x90 mm. The upper part of the rear wall will act as a heater limiter.
6. Weld the facade and the back of the stove to the body of the stove. In the middle part, the front limiter of the heater is welded, repeating the contours of the rear wall from above and the furnace body from below.
7. At the top of the case, a hole is cut out at the back with dimensions of 15x15 cm. A sheet metal arch with a hole for the chimney is installed above it, the opening should be closer to the facade by 10-15 cm - thus cutting off the flame,afterburning of fuel.
8. A chimney is welded to the vault. The vault also will serve as the bottom of the stove. To increase the volume of the heater, a grate made of reinforcement or a bar 15-20 cm high is welded over its walls.
9. The combustion chamber doors and the ash pan are hung. The oven is treated with a grinding wheel to remove traces of scale, rust. After treatment, it can be coated with a polymer heat-resistant paint and can be heated outside the sauna room for baking paint.
10. Install the oven on a base of concrete or laid in one layer of brick, porcelain stoneware, paving slabs. The chimney is led out to the street through the roof in compliance with all fire regulations: the penetrations through the floors must be carried out with the insulation of non-combustible materials, and the pipe going through the cold attic must be thermally insulated, otherwise it will form condensate and carbonic acid harmful to the metal.
11. A water tank is installed on the back of the stove. To install, you need to weld a shelf that matches the dimensions of the bottom of the tank. In the stove, stones are laid, while observing the rule: the flat part of the stones should be as close to the metal surfaces as possible for their better warm-up.

furnace. Reduction of the hard infrared radiation

Metal furnaces for a bath, despite a lot of advantages, have one drawback: they create too hard infrared radiation, which makes the air in the bath warm unevenly. Correct the situation will help the brickwork around the furnace. It is carried out close to the oven or at a distance of 5-15 cm, which provides air circulation along the walls of the furnace, and also performs a protective role - touching a heated brick can not cause serious burns, while a heated oven is very dangerous. In the lower rows of brickwork, two or three holes are made for the influx of cold air, heated by the laws of convection rises upward. About how to overlay a metal oven read on our website.

This method allows you to create a light steam and the atmosphere of a real Russian bathhouse with minimum costs. Also, we advise you to read how to choose stones for a bath and how to weld a cauldron in a bath with your own hands.
