Do you need installation of stainless pipelines? This is what we have been offering to our clients since 2005 until today.

Installation methods

When laying water supply or communications for other purposes using stainless steel pipes, several types of connections are possible, namely:

• welded;
• use of flange type connecting elements;
• crimping.

To connect using water supply and heating networks, you will need not only special equipment, but also a qualified specialist. Such a process is usually carried out, and the welding itself is performed in an inert gas environment. The most modern method that allows high-quality joining of stainless pipes is plasma welding, which also requires the use of special and expensive equipment.

Press fittings provide high-quality connections and quick installation, but are expensive and require special tools

In domestic conditions, it is not always possible to use welding, since for this you need not only to have special equipment at your disposal, but also to attract a qualified specialist to operate it. In this regard, in such cases, threadless flange or threaded fitting connections are used.

Flanges are essentially two ring-shaped elements connected to each other using studs or bolts. To achieve tightness when using flanges, use a special sealing element made of rubber or other soft polymer material. Parts such as flanges, which are quite large in size, are used mainly when pipeline elements need to be periodically dismantled and maintained, spending a minimum of time. The disadvantages of connections of this type are that they react rather poorly to temperature changes and pressure surges in the pipeline.

The service life of fittings for corrugated pipes is practically unlimited; you only need to change the seals, which can last up to 30 years

A more reliable option are fittings, the design of which includes a silicone gasket that ensures tightness. You can dismantle such connections several times without worrying about their reliability.

Grade

The dry numbers speak for themselves: we have before us an exceptionally durable and almost eternal material for water supply distribution. However, we will try to give it as unbiased an assessment as possible, weighing all the advantages and disadvantages of the solution.

pros

• Thanks to corrugation, the pipe is not afraid of water hammer. The high annular rigidity of the walls allows them to withstand high pressure, and their plasticity makes it possible to slightly change the length (and, accordingly, the internal volume) of the water supply pipe during a short-term pressure surge, acting as a damper;
• For the same reason, corrugated stainless steel tolerates freezing and thawing. Ice expanding during crystallization will not tear it, but will only cause it to slightly lengthen;
• The pipe bends easily, and the permissible bending radius is equal to its diameter. This feature means that the water supply parts do not need to be precisely adjusted to size, and also allows you to do without fittings at the bends of the water supply system;

The flexible pipe does not need corners: it bends at any angle with a minimum radius

• Stainless steel is sold in coils of 50 meters or more in length, which makes it an ideal material for laying in screeds or grooves;

Let us remind you: when installing water supply, underfloor heating and heating systems, it is highly recommended not to hide collapsible connections. They are the source of the vast majority of leaks.

• Installing pipes on compression fittings is ridiculously easy and does not require complex or expensive tools. To assemble a fitting connection, two wrenches (open-end, pipe or adjustable) are sufficient. For cutting, you can use a roller pipe cutter or grinder;

Specifications

Seamless stainless steel pipes are distinguished by their strength and resistance to rust. The absence of welds guarantees protection of products from heat-affected corrosion.

In comparison with electric-welded analogues, a number of advantages can be identified:

• The pipe does not have a weld, which is the most vulnerable area of ​​the product.
• Has the same strength throughout.

In addition, such pipes are effectively operated at high media pressures and are able to withstand destructive external influences. This makes it possible to use them in conditions of high humidity, high and low ambient temperatures. The threshold temperature for a simple carrier is 800°C, for aggressive chemicals - 350°C.

Other important characteristics include:

• The tensile strength of the material is no less than 529 N/sq.mm.
• The relative elongation indicator is at least 40%.
• The sulfur content in steel is not less than 0.02%.

The permissible curvature of products is also strictly regulated and should not exceed the following values:

• Pipes with a wall thickness of more than 0.5 mm - 1 mm per 1 m of length.
• Products with a wall thickness of less than 0.5 mm and a cross-section of more than 15 mm - 2 mm per 1 m of length.

When purchasing, you should give preference to large hardware stores and products from popular brands. Perhaps the final cost will be slightly higher, but the buyer is guaranteed to receive a quality product with the required characteristics.

Location rules

Location on the roof
When designing the installation of such combustion product removal systems, take into account the standards provided for by technical standards:

• The roof duct outlet, located on a flat roof or 1.5 m from the ridge, must have a height of at least 0.5 m.
• The chimney, located at a distance of 1.5–3 m from the ridge, reaches its level.
• The edge of the pipe, located at a distance of more than 3 m from the ridge, is flush with a line 10° from the horizon of the ridge line.
• The minimum height of the chimney is 5 m, the maximum length of the horizontal section is 1 m.
• The thickness of the channel walls for solid fuel boilers is 1 mm, devices on
• liquid fuel - 0.8 mm, for gas appliances 0.5–0.6 mm is sufficient.
• The joints of the structure do not fall on the floor.
• The passage through the roof of the sandwich pipe has a gap of 13 cm, through the ceiling - 20 cm.
• The permissible number of turns of smoke exhaust channels is 3. The diameter of the pipe is not less than that of the outlet pipe.

Features of connecting seamless stainless pipes

The main competitive advantage of such products is the absence of welds, which are the most vulnerable point of any welded pipe. For this reason, increased quality and reliability requirements are placed on the connection procedure.

Pipes are joined only by welding, and the process can be carried out manually, semi-automatically or automatically. One of the following technologies is used:

• TIG. Welding is performed in an inert gas environment, which protects the treated area from oxidation. The heat source is an electric arc formed between the tungsten electrode and the welding point. If the technology is followed, the seam will be smooth, uniform and not inferior in strength characteristics to the material of the pipe itself.
• HF. A less expensive technology, which, however, does not provide similar strength indicators. Welding is performed using high-frequency current.
• Laser Laser welding is not inferior to TIG technology in terms of seam strength, while making it possible to reduce the melting zone and make the seam less noticeable.

Thus, seamless stainless steel pipes can be safely called one of the most practical, strong, durable and environmentally friendly pipe materials, allowing you to implement any project: from the installation of industrial pipelines to the manufacture of elegant furniture. The only disadvantage of such pipes is the justifiably high cost.

Minuses

The disadvantages include the following features:

• Stainless steel is not a cheap raw material, and a corrugated stainless pipe for heating from the best manufacturers costs a decent amount.
• If you plan to design a heated floor, experts recommend using corrugation in a polyethylene braid that protects against contact with chemically active substances. In addition, the concrete screed should be replaced with a “dry” installation method.
• Corrugated pipes have an “industrial” look that will not fit into every design. On sale you can find corrugated polymer shells in different colors, which leaves some room for maneuver.
• The recesses between the corrugation rings sooner or later fill with dust, which is not so easy to clean out.

Choosing a stainless steel chimney

The stainless steel chimney design includes cylindrical sections 1.0 and 0.5 meters long, as well as numerous additional elements:

• turns at an angle of 90, 120, 135 and 150 degrees;
• adapters for connecting pipes of a different size;
• adapters for connecting sandwich and single-wall pipes;
• tees for connecting junctions;
• gates or internal dampers for adjusting draft;
• clamps for strengthening the joints of pipe sections during installation;
• brackets for attaching the external chimney to the wall of the building;
• transition glasses for crossing ceilings and roof structures with a chimney.

In the delivery set, sellers offer various fasteners for mounting and installing the chimney.

In addition to the above, you must definitely purchase a pipe head or deflector. For solid fuel units, in some cases it is necessary to use a head with a spark arrester.

If the chimney is intended to remove wood combustion products, it can be equipped with a protective cap with a mesh spark arrester

The listed components for the chimney allow you to assemble a channel of any configuration. The following requirements must be taken into account:

The total length of the chimney must be more than 5 meters. Only if this condition is met can you count on normal traction. If it is necessary to install a horizontal transition on the chimney, its length should not exceed one meter. The use of more than two turns at gentle angles in the design is undesirable. This can negatively impact your cravings. When crossing interfloor ceilings and the roof, a fire-proof crossing is required. The design of the roof penetration depends on the angle of inclination of the slope

Here it is important to ensure not only fire safety, but also tightness.

The chimney inside the boiler room is made of single pipes without insulation; all its parts located in the cold room and the external component need thermal insulation, for example, using a sandwich pipe.

When purchasing materials, pipes and components must be checked with a magnet. Suitable quality stainless steel is not magnetic. It belongs to the austenitic class, resistant to heat and aggressive environments. A similar material of the ferritic or semi-ferritic class is susceptible to corrosion, although it belongs to the stainless steel family.

The internal size of the chimney pipe is always indicated in the technical documentation for the heating unit. If a homemade boiler or stove is installed, then the cross-section of the chimney is selected in a ratio of approximately 1:10 to the size of the combustion chamber. In private homes, pipes measuring 140–150 millimeters are usually used.

The data provided will be useful in selecting the material and completeness of the device.

Application and labeling

Stainless steel corrugation is used in the following cases:

• When installing heating systems of private houses, bathhouses, greenhouses (usually a product with a diameter of 20 mm is used). They help connect heating appliances to the heating riser.
• When installing standard water supply pipelines and connecting plumbing fixtures.
• When installing heated floors and varieties (warm walls, baseboards); in heating radiators.
• As cable ducts for protecting electrical cables.
• In fire extinguishing systems as a fire-fighting pipeline.
• When laying communication networks.
• In gas supply systems.
• In internal combustion engines: transports fuel and removes exhaust gases.
