Introduction

Titanium is an important structural metal developed in the 1950s. Titanium alloys have low density, high specific strength, good corrosion resistance, low thermal conductivity, non-toxic and non-magnetic, weldable, good biocompatibility, surface with strong decorative properties, it is widely used in aviation, aerospace, chemical industry, petroleum, electric power, medical treatment, construction, sporting goods and other fields. Many countries in the world have recognized the importance of titanium alloy materials, researched and developed them one after another, and obtained practical applications.

It is hard to find more lighter and corrosion resistant material. Titanium is heat resistant, insensible to temperature changes, pressure resistant and stable in salt, moisture and organic conditions. Titanium alloy is the hardest metal. Titanium tube is required everywhere where it is important be stability to mechanical influences and endurance to aggressive media. Due to high durability, corrosion stability, accumulation of salts and organics on the wall surface titanium alloys keep its qualities and properties.

GR1 titanium welded tubes are mainly used for heating elements and exhaust system or some places that need to be bent or formed.

GR2 & GR12 titanium welded tubes are commonly used for heat exchangers, condenser and chemical equipment. In the application of chemical equipment, if the temperature of the fluid passing through the tube is normal temperature, we recommend using GR2, but if the temperature of the fluid passing through the tube is high, we recommend using GR12.

Titanium Grade 5 (Ti-6Al-4V) tubes are commonly used in aerospace, medical, chemical processing, marine, sports, and oil and gas industries. Their high strength, corrosion resistance, and lightweight nature make them ideal for applications such as aircraft components, implants, chemical equipment, shipbuilding, sports equipment, and oil and gas components.

Titanium Welded Tube Advantages
(Comparing to Titanium Seamless Tube):

√, Higher accuracy of wall thickness.

√, Thinner wall thickness.

√, Faster production lead time.

√, Cheaper price.

√, The composition of the weld seam of titanium welded tube is basically the same as that of the base material, the mechanical properties and anti-corrosion performance of the weld seam are the same as those of the base metal, and the production cycle is short and the performance consistency is good.
