Seamless titanium fittings: Size from 1/2″ to 8″; Wall thickness from SCH 5S to SCH 160. Titanium Welded Fittings: size from 1/2″ to 16″; wall thickness from SCH 5S to SCH 160S. The fittings shall be manufactured in accordance with the dimensional requirements of ASME B16.9 and MSS SP 43. And the material would be delivered as stress-relieving annealed conditions.
The titanium butt-welding fitting includes 45° & 90° elbows, 180° returns, reducers, caps, tees, crosses, lateral tees, U type bends, lap-joint stub ends, and other types. The primary application for titanium fittings is typically for chemical and water treatment industries where titanium fittings are essential due to the anti-corrosive properties and the low weight to cost ratio. Metline are approved manufacturers and suppliers of titanium fittings to several global chemical and industrial plants.
We specialise in manufacturing high quality titanium pipe fittings and titanium flanges, widely used in the petrochemical industry. In addition to various non-standard titanium fittings, Metline produces high quality Titanium elbows (LR, SR) with thick wall or custom wall thickness and bend angles which could reduce customers’ welding work.
We are a long term co-operative partner for many industrial plants across the world for supply of high temperature, high pressure, thick wall, large diameter titanium fittings and flanges used in boiler, power generation, and chemical industry. For the supplies of titanium pipe fittings and flanges, Metline has cooperated with many well-known international engineering companies, and obtained large overseas project orders and have exported to Saudi Arabia, UAE, Germany, France, UK, US, Canada, Brazil, Iran and other countries.

Beta – 21S is a metastable beta alloy that offers high specific strength and good formability, and has been designed for improved oxidation resistance, elevated temperature strength, creep resistance and thermal stability, especially in applications above 300°C.
Grade 21 :Titanium alloy including 15% molybdenum, 3% aluminium, 2.7% niobium, 0.25% silicon. Titanium alloy including 6% aluminium, 4% vanadium, and extra low interstitial, ELI23 Alloy 23 is an alpha-beta alloy based on Grade 5, providing improved stress corrosion cracking properties in seawater. Especially suited for thick wall highly stressed parts.
Grade 24 :Titanium alloy including 6% aluminium, 4% vanadium plus 0.04% to 0.08% palladium.
Grade 25 :Titanium alloy including 6% aluminium, 4% vanadium plus 0.3% to 0.8% nickel, 0.04% to 0.08% palladium.
Grade 26 :Unalloyed Titanium plus 0.08% to 0.14% ruthenium. Standard oxygen, medium strength. A corrosion-resistant titanium alloy offering outstanding resistance to general and localised crevice corrosion in a wide range of oxidizing and reducing acid environments including chlorides. Has a good balance of moderate strength, reasonable ductility and excellent weldability. Mechanical properties similar to Grade 2, but improved corrosion resistance. A competitive alternative to 7.
Grade 27 :Unalloyed Titanium plus 0.08% to 0.14% ruthenium. Low oxygen, low strength, and is the same as Grade 1, but with Ruthenium for better corrosion resistance, Grade 27 has optimum ductility and cold formability with useful strength, high-impact toughness, and excellent weldability. Very resistant to crevice corrosion.
Grade 28 :Titanium alloy including 3% aluminium, 2.5% vanadium, plus 0.08% to 0.14% ruthenium. High strength with enhanced corrosion alternative to 9.
