Titanium Steel Composite Tube
Titanium / steel composite tube pipe, uses internal pressure molds technology to produce frictional shrinkage of the inner and outer pipes, converting part of the mechanical energy into thermal energy, so that the inner pipe reaches the first softening point; the two material can interference and closely fit.
Product Introduction
The titanium and steel combination is strength, compactness, low energy consumption, The performance of the product is more stable and the structure is more perfect, excellent corrosion resistance.
The quality of the Titanium steel composite tube must meet the following requirements:
The thickness of the titanium layer should be uniform, which is an important requirement to ensure the service life of the Zr-clad copper rod. Generally, the thickness of the zirconium layer should be controlled within +/- 20%, and the thickness of the titanium layer is 0.8~3mm as your need.
titanium and steel pipe bonding rate is that the bonding area should generally be greater than 95%. The higher the indicator, the better its conductivity. Conductivity can be tested by JB/100G A type pulse reflection ultrasonic flaw detector.
titanium steel bonding strength, in the course of use, the size of this index determines whether titanium-coated steel pipe will cause titanium-steel delamination due to thermal expansion and contraction. In theory, the bonding strength should pass the shear test, but the resignation test method is a destructive test, which is generally difficult to use in actual production. Before the assembly, the titanium-clad steel tube needs a certain amount of mechanical processing. When the titanium layer is left to 0.3~0.5mm during turning and milling, if it is not separated from the substrate, the Titanium and steel bonding strength can be qualified.
Group batch requirements
Titanium steel composite tube shall be submitted for acceptance in batches. Each batch of cladding tube shall be composed of the same grade of steel, titanium, the same section shape, the same specification, the same state and the same manufacturing method.
