SEAMLESS PIPES


A seamless pipe, as the name suggests, is a pipe without a seam or a weld-joint. Seamless pipes are thought to be able to withstand higher pressure, higher temperatures, higher mechanical stress and a corrosive atmosphere. It can be found in a wide range of applications such as in oil and gas, refinery, Petrochemical, chemical, fertilizer, power, automotive, bearing, mechanical and structural.

The production of our seamless steel pipes is tightly regulated and all of the pipes we stock have been fully tested to international standards to ensure we only supply the highest quality products.

MP35N® is a registered trademark of SPS Technologies Inc.

MP35N® is a multi-phase alloy containing Nickel, Cobalt, Chromium and Molybdenum with a unique range of properties - ultra high strength, toughness, bio-compatibility and corrosion resistance. It is produced by vacuum induction melting and vacuum arc re-melting (VIM-VAR) and is then strengthened by work hardening and aging, giving hardness's of up to 55-60 Rockwell C and strength levels as high as 260-300 KSI.

Due, to this unique combination of properties, MP35N® has many applications in such industries as oil and gas, aerospace and medical. MP35N can be effectively used at cryogenic temperatures without embrittlement and maintain its properties at temperatures up to 600°F, and is also suitable for medical implants and orthodontic/prosthetic devices.

MP35N® is able to resist corrosion to most mineral acid, hydrogen sulfide and seawater environments whilst exhibiting excellent resistance to stress corrosion cracking and hydrogen embrittlement, even at high strength levels. NACE MR0175 allows a hardness of up to 51 HRC for material that has been work strengthened and aged by one of the processes listed in the table below.

Anita Steel & Metals supplies MP35N® in round bar certified to either AMS 5844 (0.270" - 1.520" diameter) or NACE MR0175 (0.5" - 2.5" diameter), as well as sheet, strip and plate products suitable for medical applications.

TITANIUM TI6AL4V GRADES

Tiatanium TI6AL4V

Grade 5, also known as Ti6Al4V, Ti-6Al-4V, Ti 6-4 or R56400 is the most commonly used titanium alloy. It has a chemical composition of 6% aluminium, 4% vanadium, 0.25% (maximum) iron, 0.2% (maximum) oxygen, and the remainder titanium. Grade 5 is used extensively in Aerospace, Medical, Marine, and Chemical Processing. It is significantly stronger than commercially pure titanium while having the same stiffness and thermal properties. Among its many advantages, it is heat treatable. This grade has an excellent combination of strength, corrosion resistance, weld and fabricability. In consequence, its uses are numerous such as for military aircraft or turbines. It is also used in surgical implants. Generally, it is used in applications up to 400 degrees Celsius. Its properties are very similar to those of the 300 stainless steel series, especially 316. Ti-6Al-4V is a two phase alpha + beta grade of titanium and is the most widely used of all the titanium grades.

Alloy 625 (Inconel®)


Alloy 625 (Inconel®*) is a nickel-chromium-molybdenum alloy with a small niobium and tantalum addition. It is an excellent general purpose material for elevated temperature use in high strength, oxidation problem areas and finds particular application in the aerospace and offshore oil & gas industries. Alloy 625 shows excellent resistance to a variety of corrosive media.

Alloy 625 demonstrates excellent resistance to pitting, crevice corrosion, stress corrosion, corrosion fatigue and erosion corrosion whilst maintaining its mechanical properties up to about 450 ºC. It is highly resistant to a wide range of organic and mineral acids combined with good corrosion resistance to high temperature sulphides and chlorides. The niobium and tantalum within the matrix act in conjunction with the molybdenum to provide a high strength alloy without the need for additional heat treatment.
