Product Introduction
The initial investment cost for titanium welded tubes is indeed
higher compared to conventional steel piping. However, the extended
lifespan and reduced maintenance frequency of welded titanium tubes
can offset the initial expenditure.
Utilizing Gr2 heat exchanger tubes in pipeline systems can decrease
maintenance costs, increase productivity, and enhance profit
margins. These tubes are predominantly fabricated into condensers
and heat exchangers, finding application in sectors such as
seawater desalination, petrochemical industries, and the power
industry.
In highly corrosive environments, the use of welded titanium tubes
is crucial to ensure equipment operates smoothly and to minimize
both the time spent on maintenance and its frequency.

Titanium welded tubes are offered with common outer diameters (OD)
including 16mm, 19.05mm, 22mm, 25.4mm, 32mm, and 38mm. The usual
thicknesses range from 0.5mm to 1.5mm, in increments of 0.1mm,
providing a selection of dimensions to cater to various
applications.
In addition to the standard round tubes, custom square and
rectangular shaped titanium tubes can be provided upon customers'
request, allowing for specialized fitments where required.
Apart from titanium, we also supply nickel and nickel alloy welded
pipes with diameters ranging from DN80 to DN1200, along with other
special metals, offering a wide array of materials for different
industrial needs.
Titanium welded tubes are frequently utilized in heat exchangers
due to their high strength, superior corrosion resistance, and
adequate thermal conductivity. The production of these tubes
involves various welding techniques such as Tungsten Inert Gas
(TIG) welding, plasma welding, and electron beam welding, ensuring
robust and high-quality joins.
When selecting a titanium welded tube for use in heat exchangers,
several factors must be considered to ensure compatibility and
optimal performance. Key considerations include the tube's
dimensions, thickness, and alloy composition, with Gr2 and Gr12
being the most commonly used titanium alloys for such applications.
The surface finish and cleanliness of the tubes are critical as
they directly affect the efficiency of the heat exchanger.
Contamination or defects in the weld can lead to reduced
performance. Moreover, it is essential to assess the mechanical
properties of the tubes, including their tensile strength,
elongation, and hardness, to guarantee they meet the necessary
specifications for the application.
