Clad Tube Sheet

In chemical production, any tube and shell heat exchanger is one of the most common unit operation equipment. But, the heat exchanger pipes must be combined with tube sheets, meanwhile, their connecting strength and sealing properties are very important. During the use, if there is a leakage around the combination parts due to medium corrosion, temperature, pressure, temperature fluctuations, etc, so the choice of high quality tube sheet is not to be ignored.

Performances of Clad Tube Sheet

  • For tube and shell heat exchangers, when single material can't stand the medium corrosion, the exchangers must use double metals tube sheets, clad tube sheets. Sometimes, even though there is only one medium corrosion, the tube sheet is larger and thinner, using clad tube sheets is less expensive than the whole precious metal materials. The clad tube sheets' properties are even higher quality in a way. The clad tube sheets are well-bonded. We need to think about the clad tube sheets as the first choice for the heat exchangers.

  • There are special metals for clad tube sheets including stainless steel-carbon steel, nickel and nickel-base alloy --carbon steel, etc.

  • Our technical team will study your specific requirements on the designer's drawings. Show Gallianz your thicknesses and diameters of the clad tube sheets, we will quickly quote you at competitive prices.

  • Gallianz sells clad tube sheet broadly around the world. Rigid supervision is executed in term of quality, including chemical component analysis, ultrasonic testing, nondestructive testing, bonding testing. We also do tensile, bend, and corrosion test as per customers' requests.

FAQs of Tube Sheet Cladding

  • What is tube sheet cladding?

    Tube sheet cladding involves applying a layer of corrosion-resistant material, such as stainless steel or nickel alloy, onto the surface of a tube sheet. This process protects the tube sheet from corrosion and wear, thereby extending its service life.

  • Why is cladding important for tube sheets?

    Cladding is crucial for tube sheets because it enhances their resistance to corrosion, erosion, and other forms of wear. This is particularly important in industries where tube sheets are exposed to aggressive chemicals, high temperatures, and other harsh conditions.

  • What materials are commonly used for tube sheet cladding?

    Common materials used for cladding include stainless steel, nickel alloys, titanium, and other corrosion-resistant alloys. The choice of material depends on the specific environmental conditions and the required properties.

  • How is tube sheet cladding applied?

    Tube sheet cladding can be applied through various methods, including:

    · Explosive Bonding: Using explosive energy to bond the cladding material to the substrate.

    · Weld Overlay: Applying a weld layer of the cladding material onto the tube sheet.

    · Roll Bonding: Using heat and pressure to bond the cladding material.

    · Brazing: Joining the cladding material using a filler metal.

  • What are the benefits of tube sheet cladding?

    · Corrosion Resistance: Protects against chemical and environmental corrosion.

    · Enhanced Durability: Increases the lifespan of the tube sheet.

    · Cost Efficiency: Reduces maintenance and replacement costs.

    · Performance Improvement: Ensures consistent and reliable performance in harsh conditions.

  • In which industries is tube sheet cladding commonly used?

    Tube sheet cladding is widely used in industries such as:

    · Oil and Gas: For heat exchangers and pressure vessels.

    · Chemical Processing: In reactors and condensers.

    · Power Generation: For steam generators and condensers.

    · Marine: In desalination plants and ship components.

  • How do you choose the right cladding material for a tube sheet?

    Choosing the right cladding material involves considering factors such as:

    · Corrosive Environment: Type and concentration of corrosive agents.

    · Operating Temperature: Maximum and minimum temperatures the tube sheet will be exposed to.

    · Mechanical Stress: Expected mechanical loads and stresses.

    · Cost: Balancing performance requirements with budget constraints.

  • How is the quality of tube sheet cladding ensured?

    Quality assurance involves:

    · Non-Destructive Testing (NDT): Methods like ultrasonic testing, radiographic testing, and dye penetrant inspection.

    · Destructive Testing: Such as tensile and shear tests to evaluate the bond strength.

    · Visual and Dimensional Inspection: To check for defects and ensure proper dimensions.

    · Adherence to Standards: Following industry standards and specifications.

  • Can cladding be repaired or reapplied if it gets damaged?

    Yes, cladding can often be repaired or reapplied. The specific method of repair will depend on the type and extent of the damage, as well as the original cladding method used.
