Enjoy a dream stay in nature hidden in a “tube”

Yes, there is the Tubohotel. In Mexico, in the garden of Tepotzotlán, half an hour away from the capital Mexico City, there is a hotel immersed in nature, where one sleeps in concrete tubes stacked in pyramids.

The Tubohotel has 20 rooms, each measuring 2.44 m wide by 3.5 m long. Each room, that is each tube, can accommodate two people and has a large bed that takes up almost the entire suite; however, there is no space for indoor bathrooms, but guests have access to two common services.

China: more tariffs on US and EU pipes

China decided to increase anti-dumping duties on some types of seamless stainless steel tubes for high temperatures and pressures from the USA and the EU. The 13-14.1 percent duties that had come into force in 2014 were extended and increased exponentially, welcoming the request of local producers. “The applicable anti-dumping rate – reads the government document – is between 57.9% and 147.8%”.

As for the pipes coming from the EU, the duty is 60.8%, also for the Italian IBF spa, expressly mentioned in the provision and part of the Tubacex group. For Vallourec Germany and France, the measure will stop at 57.9%. In three figures, on the other hand, the duty that will now be imposed on the import of this type of tube from the United States: it will be 147.8% and 101% for Wyman-Gordon Forgings.

Tecnofar, specialist in stainless steel tubes

Tecnofar spa manufactures and sells high-performance longitudinally welded stainless steel and nickel alloys tubes, in particular:

  • austenitic stainless steels
  • duplex stainless steels
  • ferritic stainless steels
  • alloys with a high nickel content

Located in the North of Italy, in a green area, surrounded by the Italian and Swiss Alps, Tecnofar Spa  has recently increased its production unit with a modern 5000 m2 plant, opened on January 2016.

Working with the most important European stainless steel mills, at the base of supply chain, Tecnofar offers a semi-finished quality product, fundamental requirement for a cost-efficient and environmentally-friendly component part.

Tecnofar Used in various applications, like alimentary, heat exchanger, medical etc..,

In automotive industry, Tecnofar’s tubes are fundamental part of components mounted on millions of passenger cars and commercial vehicles around the world.

Some application examples:

-Pipelines (Fuel/Oil/Air)                                                  -Glow Plugs- EGR Tubes                                                                       -Exhaust Systems

An advanced engineering department and a vision that drives us continuously looking for improvements and technological developments, at a competitive price, make Tecnofar a leading manufacturer of quality stainless steel tubes.

With this aspect, combined with the constant attention to customer needs, Tecnofar contributes to increasing the performance of his customer’s products.

The 11 Tig welding lines are equipped with the most efficient control systems  and induction annealing furnaces, that, working in a protected atmosphere, give to Tecnofar tubes an high corrosion-resistant resistance and the right mechanical characteristics  to perform bending, hydroforming, expanding, drilling, flanging etc …

A large part of Tecnofar’s production is dedicated to standard diameters like (ODxWT) 5×1, 6×1, 6×0,7, 8×1, 10×1, 12×1, 12,7×1, 14×0,3, 13,5×0,4, 20×0,4, 14×1, 16×1, 19×1, 22×1, 30×0,5, 41,20×1, 50×1, 50×2,  53×1, 55,8×1, 66,4×1,2, 71,2×0,8 mm.

Tecnofar tubes are regularly subjected to the most strict control tests,  in according with specific standards:

  • ASTM:
    A240- A480 A249- A269- A270- A312- A358- A530- A554- A632- A778- A908- B751- A269- A803- A789 – A790
  • DIN:
    11850
  • EN:
    10088/2 – 10217/7 – 10312 – 10296
  • PED:
    97/23/EC ANNEXI par 4.3

Production range for welded tubes goes from 3 to 76 mm and thickness from 0,15 to 3 mm, with possibility of heat treatment and surface finishing by satinizing (grain 60 – 800 micron)

To meet the production requirements of all the customers, Tecnofar tubes could be supplied in long bars, in coils, or  in fix length cut pieces, perfectly deburred and cleaned.

To expand its production capacity for cut pipes Tecnofar has started a new and modern 4.0 plant to cut, deburr, wash, and check pipe segments with a diameter between 8,00 mm and 76,00 mm in lengths between 90 mm and 1000 mm, equipped with automatic loading and issuing of control reports (with Cpk).

The new plant integrates an already advanced department that is composed of 10 machines able to cut directly from bar or from roll tubes of diameter included between 1,00 mm and 76,00 mm and lengths from 3,00 to 3000 mm.

All this is done with a view to provide a quality product, always closer to the customer’s needs.

Directly connected to the production of stainless steel welded tube, Tecnofar is producing welded cold-drawn precision tubes with an external diameter ranging from 0,3 to 20 mm and thickness from 0,1 to 2 mm, available in bar, rolls and cut to size,  used in the application which require a very high precision and quality.
