Tubes- seamless - Import export

Seamless aluminium tubes can be ordered in all commercially available aluminium alloys in addition to high strength aluminium alloys which are required for more demanding applications. ALUnna has a number of extrusion presses equipped with mandrel piercing capability. This allows us to extrude a large range of extruded tubular dimensions from a number of different billet diameters. The size range for seamless extruded tubes ranges from 17 mm to 300 mm in diameter.

Durability and corrosive resistance are key criteria when it comes to precision thin wall tubing for industrial condensers. The tube mill at Superior Tube more than meets that requirement, and we supply products to a range of leading engineering companies. In the energy sector, our high quality stainless steel and nickel alloy condenser tubes are used for the cooling, heating or re-heating of fluids or gases within steam turbines that generate electricity.

UNS NO8904, commonly known as 904L, is a low carbon high alloy austenitic stainless steel which is widely used in applications where the corrosion properties of AISI 316L and AISI 317L are not adequate. The addition of copper to this grade gives it corrosion resistant properties superior to the conventional chrome nickel stainless steels, in particular to sulphuric, phosphoric and acetic acids. However, there is limited use with hydrochloric acids. It also has a high resistance to pitting in chloride solutions, a high resistance to both crevice and stress corrosion cracking. Alloy 904L performs better than other austenitic stainless steels due to the higher alloying of nickel and molybdenum. The grade is non-magnetic in all conditions and has excellent formability and weldability. The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures. Please note that we have a minimum order value of £10,000.

The high precision seamless tubes manufactured at Fine Tubes begin their journey as seamless tube extrusions, in a range of different sizes. This material is reduced in size several times until it gradually reaches the exact specifications our customers require. Each time we perform a reduction process, the tube needs to be cut, cleaned and heat treated before the next one can commence. Please note that we have a minimum order value of £10,000.

Aluminiumwerk Unna AG is specialised in the production of Aluminium tubes. The Aluminium tubes are extruded on site using two possible methods. These are either Seamless extrusion or Porthole extrusion. It is quite simple to distinguish between the two extrusion methods. In seamless extrusion, a mandrel is positioned and fixed inside the extrusion die, creating the inner contour of the tube. In porthole extrusion, the mandrel is fixed and is supported by a number of integral bridges affixed to the outer portion of the extrusion die.

Seamless tube elbows made of aluminum for welding.

Alloy 22, is a versatile austenitic nickel-chromium-molybdenum-tungsten alloy with enhanced resistance to pitting, crevice corrosion and stress corrosion cracking. The high chromium content provides good resistance to oxidizing media while the molybdenum and tungsten content give good resistance to reducing media. This nickel alloy also has excellent resistance to oxidizing aqueous media including wet chlorine and mixtures containing nitric acid or oxidizing acids with chlorine ions. Alloy 22 has resistance to oxidizing acid chlorides, wet chlorine, formic and acetic acids, ferric and cupric chlorides, sea water, brine and many mixed or contaminated chemical solutions, both organic and inorganic. This nickel alloy also offers optimum resistance to environments where reducing and oxidizing conditions are encountered in process streams. This is beneficial in multi-purpose plants where such “upset” conditions occur frequently. Please note that we have a minimum order value of £10,000.

Superior Tube is committed to improving healthcare options for patients, and to helping surgeons save lives. As such, we manufacture a range of specialized welded and seamless tubing products for various areas of the medical device industry, including cardiac stents. Stents are small, expandable tubes, usually made of metal mesh, and are used to treat narrowed or weakened arteries. In patients with coronary heart disease, stents are implanted in order to open narrowed arteries during a procedure called percutaneous coronary intervention, or angioplasty. Heart stents can also help relieve chest pain and aid in the prevention of heart attacks. Ever since our tubing was used in the earliest cardiac stent implants in 1987, Superior Tube has been an industry leader in the manufacture of implant grade tubing for both coronary and peripheral stents. Please note that we have a minimum order value of £10,000.

Alloy 209 is a fully austenitic nitrogen strengthened stainless steel, having twice the yield strength and superior corrosion resistance at room temperature when compared to 316/316L or 317/317L stainless steels. This grade does not become magnetic when cooled to sub-zero temperatures or to a cold working process and has high resistance to sulphide stress corrosion cracking in both annealed and cold worked/ cold worked & aged form up to 30 HRc hardness. Please note that we have a minimum order value of £10,000.

Alloys 304 (S30400) and 304L (S30403) stainless steels are variations of the 18 percent chromium – 8 percent nickel austenitic alloy, the most familiar and most frequently used alloy in the stainless steel family. High strength, excellent corrosion resistance and minimized carbon content make Alloy 304 and 304L Stainless Steels useful for applications where welding is required. Uses include architectural mouldings and trim, welded components of chemical, textile, paper, pharmaceutical and chemical industry processing equipment. Other advantages are its resistance to oxidation, excellent formability, ease of fabrication and cleaning, excellent strength to weight ratio and good toughness at cryogenic temperatures. For severely corrosive environments,the lower content of Type 304L is preferred because of its greater immunity to intergranular corrosion. Please note that we have a minimum order value of £10,000.

Stainless steel grades cover a wide range of compositions which result in the generation of a variety of microstructures and mechanical properties. This group of alloys is useful for the replacement of mild steel in structures and components. Stainless Steel tubes manufactured by Fine Tubes have an excellent combination of corrosion resistance, metallurgical stability and formabilityStainless steels are favoured because they are very cost effective. They also have an excellent combination of corrosion resistance, metallurgical stability, formability, and are easily welded.
