TU 48-4-311-74. Tubes of tantalum-tungsten alloys. TV-15, TV-10, TV-5
Are you interested in TU 48−4-311−74 «Pipes made of tantalum-tungsten alloys» from the supplier company AvecGlob? Here you will find the necessary information on this topic.
Application area
These technical specifications apply to tubes made of tantalum-tungsten alloys TV-5, TV-10 and Tv-15, which are used for the manufacture of parts of electric vacuum technology, heat exchangers, cooling devices, heaters, pipeline components, etc.
Properties
The material of seamless pipes according to TU 48−4-311−74 is tantalum-tungsten alloy of TV-5 grades (tantalum — 95%, tungsten — 5%), TV-10 (tantalum — 90%, tungsten — 10%) and TV- 15 (tantalum — 85%, tungsten — 15%). Pipes are produced by the method of cold deformation from rods.
Advantages of tantalum-tungsten tubes
Pipelines made from tantalum-tungsten alloys are suitable for any application where corrosion is a factor in reducing equipment downtime and increasing the longevity of its operation. While the initial purchase price is higher than that of a number of other materials (graphite, ceramics, glass, etc.), tantalum-tungsten pipelines will be economically profitable for several decades. Pipes made of the alloys TV-5, TV-10 and TV-15 are not brittle and do not crack like carbon graphite. They allow high-quality welding and high tightness.
Operational advantages of tantalum pipelines:
Excellent corrosion resistance;
Possibility of providing high vapor pressure;
Elimination of leaks of technological working environments.
Features
Tantalum and tungsten are the most corrosion-resistant metals. They are inert to practically all organic and inorganic compounds, as well as to sulfuric and hydrochloric acid at temperatures up to 150… 200 ° C, and, for short-term use, up to 250 ° C.
Tantalum-tungsten alloys have good thermal conductivity and resistance to erosion, has a high degree of efficiency and weldability. This makes them an ideal material for pipes for corrosion-resistant reactors.
Supplier — AvekGlob Company — offers seamless cold-deformed tubes from tantalum-tungsten alloys of TV-5, TV-10, TV-15, which meet the requirements of TU 48−4-311−74.Products are offered at affordable prices from the manufacturer. The supplier guarantees the timely delivery of seamless pipes to any address specified by the customer.
