Aphorism «all is not gold that glitters," can be fully attributed to the mirror tube — in quality and aesthetic appearance it gives a little gold.
dignity
Stainless mirror pipe — a pipe made of stainless steel with a perfectly polished surface. Another name — mirrored tube — polished stainless. It is remarkable for the exceptional quality of the surface. Here are the main advantages:
- The mirror surface makes it difficult to build-up of dirt.
- On the polished (electropolished) maximum surface Cr / Fe ratio, which increases the corrosion resistance.
- On the surface of the smallest defects visible.
- High mechanical strength, abrasion resistance by reducing stresses locations.
Complex alloys with a high percentage of chromium, molybdenum, nickel, silicon, different maximum resistance. Depending on the temperature, concentration of aggressive factors selected brand alloy with the desired set of properties.

disadvantages
The difficulty in the inner surface treatment eliminates the use of HF-mirror tube (welded microwave welding) in medicine, food industry, pipelines, working under pressure.
Production
Used stamps — AISI 316 or AISI 304 (in limited positions) according to standards: DIN 17457 and DIN 72 263. DIN 2263 normalizes the quality of the pipes, which produce high-frequency HF-welding of stainless strip. HF-welding speed to 40 m / 1 min., Which substantially reduces the cost of the pipe. Such pipes are ideal for design solutions, but are suitable for the food industry. They are 30% less than those produced by TIG-welding, and the weld but have 20% less durable.
Welding
100% strength ensures TIG- welding (Tungset Inert gas). The seam thickness of 25 mm, smoothed flush (DIN 17457). The seam becomes as smooth as the surface of heat treated stainless steel tube. The inner surface of the seam for the food industry should just finish grinding. Label such as the stainless mirror pipe SS. DIN 11 850 normalizes pipe heat treatment (for example, bright annealing) Chemical treatment (etching) and grinding process.
| The surface | Clean grinding |
|---|---|
| The inner surface of the weld | up to 1,2 mm |
| The main material of the pipe | 0,8 — 1,8 mm |
| Outside surface | up to 1 mm |
Polished to mirror grinding tube units (number of brushes at least 5, usually 6) using a polishing pastes 1−2 finishing brushes. When grinding the grain size should be between 600 grit and higher. Polished inside (and outside) the electrochemical method, known as «chemical treatment process» and / or «plating process variable», which is considerably more efficient machining. Electropolishing smooths flaws, giving luster surface. With the proper ratio of temperature of electrolyte and current strength, surface defects with high electric current density is selectively removed to give a very smooth surface.
Using
The appearance of such pipes very attractive. They are in demand in the design of residential buildings, offices and shopping malls. Aesthetics is important mirror pipes and plumbing systems, particularly in the sewer systems. Each pipe is given a quality certificate of the manufacturer. For decorative purposes, such pipes are not subject to obligatory sanitary or other certification.
