We can produce products DN15-5000 diameter tube sheets with GB standard, American Standard, Japanese standard, European standard, and non-standard flange. Products are widely used in petrochemical engineering, food, metallurgy, construction, electric power, and other machinery. Product quality and yield have been a qualitative leap.

The tube plate is in a circular plate on the drill pipe diameter is slightly larger than the same hole, pipe penetration welded fixed, plays a role of such accessories.

In the calculation of fixed tube plates in various working temperatures to calculate casing axial stress, axial stress, and heat pipe between the heat pipe and pipe plate pull-out force Q, one can not meet the strength (or stable) conditions and will need to set expansion joint. In the fixed tube plate strength calculation, when the tube plate thickness is determined, no expansion joint, sometimes tube plate set expansion joint, and strength is not enough, the tube plate thickness could meet the requirements. At this point, it can also be set up to reduce the expansion section of the thin tube plate, but from the material consumption, manufacturing, safety, and economic results and other comprehensive evaluation.

Fixed tube plate heat exchanger is widely used in U-type expansion joint, which has simple and compact structure, good compensatory, cheap, etc.

The tube plate machining accuracy, especially the tube hole spacing and diameter tolerances, verticality, and smoothness have a great impact on the above assembly and use performance of chemical equipment. With the chemical equipment, and power station of large, the diameter of the tube plate is becoming larger and larger, a diameter of tube plate very common 4m-5m. Large tube plate is characterized by a large number of tube holes, and dense, small, deep, deep, precision, and smooth finish requirements.

Tube plate usage

The tube plate is widely used in heat exchangers, boilers, pressure vessels, steam turbines, and large central air-conditioning industries.

Mainly used for chemical containers, such as heat exchangers, pressure vessels, boilers, condensers, evaporators, central air conditioning, desalination, supporting fixed tubes, metal material which not only has strong rigidity but also has great heat conduction performance.

Tube sheet material

Depending on the need to use the environment, the use of different materials, the general use of Q345R containerboard, such as the one or two pressure vessels, no corrosive media flow, using carbon steel composite plate. Strong, high temperature,s and high pressure, such as nuclear power environment requires 16 stainless steel, manganese, corrosion resistance of titanium alloy material, and the application of new synthetic materials, to the tube plate products bring new vitality.

Tube sheet processing

For tube plates, three or four types of pressure vessels need high precision, hole processing method is the traditional fitter, rocker drill. With the chemical container of large-scale, the diameter of the tube plate is also increasing, the thickness is gradually thick, the tube sheet is also introduced into the numerical control technology, the use of CNC drilling hole with the rocker drilling hole processing. The use of machining centers to do high-efficiency and high-precision machining has gradually been accepted by a number of large enterprises. Large thick tube plates in nuclear power, seawater desalination, and the central air conditioning heat exchanger is of the demand a growing trend.

Tubesheets Fabrication

Tubesheets square measure one of the foremost vital parts of Shell and Tube Heat Exchangers. These components square measure sometimes made up of a spherical flat piece of cast materials that square measure machined with holes trained for the tube ends in an exceedingly precise location and pattern relative to 1 another. Tube holes are often trained and reamed and may be machined with one or additional grooves that greatly will increase the strength of the tube joint. Fabrication Our workshops are equipped with fashionable machinery together with CNC drilling machines so as to create any tube sheets. These components square measure wide used for the fabrication of warmth exchangers in any configuration. All machining activities like shaping machine machining, drilling, reaming, taping, grooving, and surface edge are often disbursed specifically in keeping with clients' drawings and specifications. As all of the drilling activities are programmed on laptops and done by state of art CNC machinery, there wouldn't be any potential mistakes caused by humans.

Heat Exchanger Tube Sheet

- Size and form

Any size and form of tube sheet wont to build a TEMA or maybe non-TEMA sort are often provided. Our drilling facilities that square measure equipped with deep drilling mechanism square measure able to drill terribly thick plates straightly while not a deviation from acceptable tolerances.

Condensor Tube Sheet

- Material

The strict use of top-quality staples is secure and evidenced by a staple certificate with every delivery. Material varies is varied from standard steel to steel, all grades of stainless steel, non-ferrous (Brass, Al-Brass, Copper Nickel), and a big selection of Clad Steel consisting of corrosion-resistant materials.
