Over 900 Perforated Baffle Plates Export to Italy For Oil Refining Industry

Recently, more than 900 baffle plates for a large refinery project in Italy were shipped smoothly. After inspecting the products, the customer affirmed our processing technology and product quality. And they indicated that they would continue to cooperate with us in the future.

What's a Baffle Plate?

A baffle plate is a piece of metal or other material used in various applications, including heat exchangers, boilers, and other types of process equipment. The main purpose of a baffle plate is to direct the flow of a fluid or gas and to support tubes.
Baffle plates are typically made of materials that are able to withstand high temperatures, pressures, and corrosive environments, such as stainless steel or other high-alloy steel. The manufacturing process may involve various metal fabrication techniques, such as cutting, drilling, and welding.
Baffle plates are an important component in a variety of industrial applications, helping to optimize the performance and efficiency of process equipment and to ensure safe and reliable operation.

Types of baffles in heat exchangers

Baffles in heat exchangers are often used as a core element in any shell and tube heat exchanger design. There are different types used in heat exchangers, below are the popular ones:

• Segmental baffles
  A plate-type baffle may be single-segmental, double-segmental or triple-segmental. Single and double segmental baffles are most frequently used as they divert the flow most effectively across the tubes.
• Disk and Doughnut baffles
  Has alternating outer rings and inner disks which directs the flow radially across the tube field. They all very effective in pressure drop to heat transfer conversion.
• Orifice baffles
  In this type of baffles the shell side fluid follows through the clearance between the tube outside diameter and the baffle hole diameter.
• Rod baffles
  This type is metal rods rather than plate metal baffles. The type is use wherever a very low-pressure drop is required. Rod baffles also eliminates the tube vibrations which occur with plate baffles when fluid velocities are high.
  The flow in the shell side is mainly parallel to tube axis. Tubes are arranged with square pitch. Rods, with a diameter equal to the clearance between the tube rows, are attached to ring supports and placed between alternate tubes in both horizontal and vertical directions.
  Rod baffles are mainly used when the pressure drop available is very low or there is a pressure drop issue.

Our Capability in manufacturing tube sheets and baffles

Since last year, we have maintained a 10% monthly growth in the processing of tube sheets and baffle plates. In response to the growing demand, Openex introduces advanced processing equipment to ensure our advantages in the manufacturing of tube sheets and baffle plates.

At present, we have 53 sets of various advanced drilling equipment, including 11 sets of deep-hole drilling machines, 31 sets of CNC multi-hole drilling machines and 11 sets of CNC lathes, which can realize the precision drilling and machining services of high precision, complete specifications and multiple functions, among which the most service products are all kinds of tube sheets/plates, flanges and so on.

Our Drilling Capabilities:

Deep Hole Drilling
- Max Hole Depth 1200mm
- Hole Dia Range 12mm-55mm，
- Max Thickness 1200mm
It has a stable aperture size, excellent hole wall roughness, and high verticality. It can process the tube plate with a thickness of 1200mm and realize biaxial and triaxial processing at the same time. The efficiency is 2-3 times that of the traditional processing method.

Multi-Hole Drilling

Our porous drilling equipment can be processed by four axes at the same time, support multiple partitions stacked, the processing table is large(length * width 12000mm*10000mm) with high efficiency, max depth of 300mm, and the maximum aperture can be 105mm. We have served the central air conditioning, boiler, heat exchanger, seawater desalination, power station and other industries.
