Why Choose Ultra Long Molybdenum Tubes?
Manufacturing a 3200mm long molybdenum tube requires more than standard machining capability.
Long refractory metal tubes require careful control of:
Straightness
Wall thickness consistency
Inner and outer diameter tolerance
Surface quality
Mechanical strength
Handling and transportation
High-temperature performance
For extra-long molybdenum tubes, dimensional consistency over the entire length is especially important.
Our production process focuses on maintaining stable quality from one end of the tube to the other.
Material Options
Pure Molybdenum Tube
Pure molybdenum offers excellent high-temperature strength, a high melting point and good thermal conductivity.
It is commonly used in:
Vacuum furnaces
High-temperature heating systems
Thermal shielding
Semiconductor equipment
Sapphire crystal growth
Powder metallurgy equipment
Lanthanum Molybdenum Tube
Lanthanum molybdenum offers improved high-temperature performance and recrystallization resistance compared with conventional pure molybdenum.
It is suitable for demanding applications requiring:
Long service life
High-temperature stability
Improved creep resistance
Better dimensional stability
TZM Molybdenum Alloy Tube
TZM is a molybdenum alloy containing titanium, zirconium and carbon.
It provides higher strength and improved performance at elevated temperatures compared with pure molybdenum.

Semiconductor Equipment
High-purity molybdenum components are used in specialized semiconductor and thermal processing equipment.
Powder Metallurgy
Long molybdenum tubes can be used in sintering furnaces and other high-temperature processing systems.
Custom High-Temperature Equipment
We also manufacture customized molybdenum components according to customer drawings and application requirements.
Quality Control
Each ultra-long molybdenum tube can be inspected according to customer requirements.
Typical inspection items include:
Outer diameter inspection
Inner diameter inspection
Length measurement
Wall thickness inspection
Straightness inspection
Surface inspection
Material verification
Dimensional tolerance inspection
For critical applications, inspection reports can be provided upon request.
Packaging for Extra Long Molybdenum Tubes
Because a 3200mm molybdenum tube is significantly longer than standard industrial tubes, proper packaging is essential.
We use suitable protective packaging to help prevent:
Bending
Surface damage
Impact damage
Transportation damage
Packaging can be customized according to tube dimensions and shipping requirements.
