Shell and tube heat exchanger

What is a shell and tube heat exchanger? What is the core function?
Shell and tube heat exchanger is a commonly used heat exchange equipment in the industrial field. It consists of two main parts: an outer sealed cylinder (shell side) and an inner densely arranged tube bundle (tube side). Its core function is to transfer heat between two different temperature media (liquid, steam, etc.) without contact between the cylinder and the tube bundle. Simply put, it cools the high-temperature medium and heats up the low-temperature medium to achieve heat recovery, temperature control, and avoid energy waste. It is an essential heat exchange equipment in industries such as chemical, HVAC, and food.

Our shell and tube heat exchanger is suitable for a wide range of scenarios, whether it is conventional HVAC refrigeration heat exchange, or industrial high-temperature, high-pressure, and corrosive medium heat exchange, it can be perfectly adapted. For many years, we have supplied customers from various industries around the world, accumulated rich experience in scene adaptation, and eliminated the problem of being unable to use after procurement.
–Chemical industry: Heat recovery, cooling and heating of various chemical media, corrosion-resistant stainless steel heat exchangers suitable for strong acid and weak alkali working conditions

–Heating, Ventilation, and Air Conditioning (HVAC): Large shopping malls, office buildings, and factories are equipped with central air conditioning systems that utilize efficient and energy-saving heat exchangers to save energy

–Food and medicine: Sanitary grade stainless steel style, in line with the hygiene standards of the food and medicine industry, easy to clean, and residue free

–Electric printing and dyeing: power plant waste heat recovery, printing and dyeing plant water temperature control, high and low temperature resistance, strong long-term operation stability

–Other industries such as metallurgy, environmental protection, and new energy have heat exchange needs that can be adapted as needed.

1. CNC Drilled Tubesheets
All tubesheets are CNC machined, not manual drilling. Hole tolerance within ±0.1mm. Multiple tubesheets stacked and drilled together for perfect alignment.

2. Quality Tubes Only
We use mill-certified tubes from major steel mills. No secondary grades, no repurposed material. Incoming inspection covers wall thickness, OD, and hardness.

3. Precision Baffles
Baffles are cut flat and true. Hole positions match tubesheets exactly. Spacing held to drawing tolerances for proper flow distribution.

4. Certified Welding
All welders are certified. Critical welds get NDT inspection—X-ray or dye penetrant as required. Slag removed, beads ground clean.

Whether it’s a standard model or a non-standard design, as long as you provide the drawings, we can manufacture a shell and tube heat exchanger that meets your requirements according to the drawings.

We keep packaging simple and practical: small units go in cartons, large ones go in wooden cases.

📦 Carton packaging (for small units)

• Reinforced corrugated cartons

• Foam lining inside, no shifting during transit

• Perfect for small shell and tube condensers used in refrigeration or lab equipment

🪵 Wooden case packaging (for large units)

• Solid plywood cases with pallet base

• Unit bolted to the base—won’t move during shipping

• Reinforcement bars on all sides

• Fumigation available for export orders
