Liquid Medium Heat Exchanger for LNG Gas Station

Introducing the NOBLEST Shell and Tube Heat Exchanger This fixed tube-plate heat exchanger boasts a simplistic yet efficient design, comprising a tube plate and shell at both ends. Widely utilized, this model features tube plates welded to the shell, which can also serve as a flange after welding. Connected to the pipe box flange by bolts, it's a robust solution for a variety of applications.

Applications: As an energy-saving marvel, this heat exchanger facilitates heat transfer across materials and is extensively used in petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food sectors. The continuous evolution in energy-saving technologies has amplified its role in high and low temperature heat recovery, bringing noteworthy economic advantages.

Advantages of this heat exchanger include its simple structure, optimizing the shell's inner diameter while preserving the heat transfer surface. However, significant temperature differences between shell and pipe mediums may induce thermal stress, causing potential failures, leakages, or instability. Maintenance and cleaning tasks on the shell side may also be cumbersome. Despite these limitations, it remains a preferred choice for general applications with manageable temperature differences.

Presenting the NOBLEST U-shaped Type Tube Heater This type, a key component in the petrochemical domain, consists of a tube box, shell, and a U-shaped tube bundle, all fixed on a single tube plate. Its design ensures efficient performance and reliability.

Key Features :
Δ The tube bundle can expand and contract freely without thermal stress due to temperature differences.
Δ Excellent thermal compensation performance.
Δ Enhanced heat transfer performance due to the double-tube flow design, resulting in a longer path and higher flow velocity.
Δ High pressure resistance.
Δ Easy maintenance and cleaning with a simple, cost-effective structure as the tube bundle can be withdrawn from the shell.

Applications:
Ideal for conditions with large temperature differences between the tube and shell walls, situations where the shell-side medium is likely to scale while the tube-side remains clean, and environments requiring high temperature, high pressure, and strong corrosion resistance.

Discover the NOBLEST Floating Head Heat Exchanger Featuring a design where only one end of the tube plate is fixed to the shell, the floating head allows the other end to move freely, accommodating thermal expansion without stress. Comprising a floating tube plate, hook ring, and a floating head end cover, this unit can be fully dismantled for easy maintenance.

Key Features:
This model excels in ease of cleaning between tubes, free from thermal stress. Nevertheless, its complexity and higher cost, alongside bulkiness and increased material usage, pose some challenges. Notably, the small floating head cover requires meticulous sealing and cannot be inspected during operation, making it suitable for scenarios with significant temperature variations or easy scaling of the shell medium.

Applications:
Δ The tube bundle is designed for effortless extraction, ensuring easy and effective cleaning of both the tube and shell processes;
Δ Unrestricted by temperature differences between mediums, it offers versatile adaptability in diverse conditions;
Δ Engineered to perform seamlessly under high temperature and high-pressure environments, enduring up to 450 degrees Celsius and pressures up to 6.4 MPa;
Δ Exceptionally suitable for scenarios with severe scaling, ensuring reliable performance;
Δ Highly resistant to pipe corrosion, making it ideal for corrosive environments.
