Invar Pipes

Invar Pipe is an iron-nickel alloy that can produce insignificant thermal expansion and is used in many industries. It comprises 64% iron and 36% nickel; due to its extraordinary characteristics, it is used in precise equipment such as cryogenic, aerospace, and instruments. 

Advantages of Invar Pipes

Invar Pipe is a highly durable and versatile material widely used in various industries.

• Minimal Thermal Expansion: Invar Pipe has a very low coefficient of thermal expansion and is thus suitable for use in applications that demand stability in size change with temperature.
• High Precision: The material can maintain the structural integrity and precise dimensions that help it perform well in critical and precise industries, including aerospace and instrumentation.
• Excellent Corrosion Resistance: Invar Pipe has a high resistance to corrosion and thus can be used in long-term applications where the environment is unfriendly or the application causes corrosion of the Pipe.
• Cryogenic Suitability: This characteristic makes it most suitable for cryogenic systems and storage tanks since it performs remarkably at very low temperatures.
• Durability: The high strength and durability of steel pipe ensure its long service life, even under mechanical or environmental stress.
• Weldability and Machinability: This material can be easily welded and machined, which gives a broad range of opportunities in construction and manufacturing.
• Stable in Vacuum and High-Pressure Applications: It is used in scientific industries due to its flexibility in working under high vacuum and pressure conditions.
• Magnetic Stability: Invar is stable in magnetic properties and favourable for electromagnetic devices or field applications.

These characteristics make Invar Pipe ideal for use in sectors that demand high-performance levels.
