Product Specification

DINKONDA GLOBAL Power Plants Special Ultra Strong Acid, Strong Oxidizing Medium, Halide Hastelloy Heat Exchanger, Shell And Tube Carbon Steel/stainless Steel Heat Exchanger

Product Overview
This Hastelloy heat exchanger tube bundle and contact medium components are made of Hastelloy material and designed for strong corrosive chemical working conditions. It can withstand harsh corrosive environments such as strong acids, strong oxidizing media, halides, etc. Through a shell and tube structure, heat exchange between the two process media is achieved. It is widely used in heating, cooling, condensation, and waste heat recovery processes of strong corrosive processes such as fine chemicals, wet metallurgy, and coal chemicals.

Structural Composition
1. Shell: Manufactured according to pressure vessel standards, the shell can be made of carbon steel or stainless steel, equipped with medium connections, exhaust ports, and discharge ports to meet pressure and maintenance needs.

2. Heat exchange tube bundle: The heat exchange tubes are made of Hastelloy (C-276/C-22, etc.), and the tube plates are made of Hastelloy composite plates. The expansion welding bonding process is used to eliminate the hidden danger of crevice corrosion and prevent medium leakage.

3. Pipe box and head: The contact area with corrosive media adopts Hastelloy integral or lining structure, equipped with high-pressure flange components to ensure sealing performance under high-pressure and strong corrosion conditions.

4. Baffle plate: supports the heat exchange tube bundle, disturbs the shell side fluid, increases the heat transfer coefficient, and reduces tube bundle vibration caused by fluid impact.

5. Saddle support: supports the weight of the entire machine, can absorb displacement caused by thermal expansion of equipment, and reduce damage to equipment caused by thermal stress.

6. Accessory pipeline accessories: equipped with pressure gauge interfaces, venting and sewage components for easy on-site monitoring, operation and maintenance.

Core Features
1. Ultra strong corrosion resistance: Hastelloy can resist wet chlorine gas, hydrochloric acid, sulfuric acid, phosphoric acid, chloride, and mixed strong corrosive media, solving the strong corrosion conditions that ordinary stainless steel and titanium materials cannot handle, effectively avoiding pitting corrosion, crevice corrosion, and intergranular corrosion.

2. High heat transfer efficiency: The shell and tube structure has sufficient heat transfer area, sufficient fluid disturbance, stable heat transfer performance, and can achieve continuous heat transfer under high temperature and high pressure conditions.

3. Reliable sealing and long service life: tube bundle expansion welding combined with process, resistant to medium penetration; Alloy materials have excellent mechanical properties, high temperature resistance, fatigue resistance, and reduce equipment replacement and downtime losses.

4. Drawable bundle structure for easy maintenance: The bundle can be removed for easy cleaning of scaling on the tube and shell sides, and for easy detection of corrosion in the heat exchange tubes.

5. Pressure and high temperature resistance: Designed and manufactured strictly in accordance with pressure vessel specifications, it can adapt to high temperature, medium high pressure chemical process conditions; Expansion joints can be added to compensate for thermal deformation based on temperature differences.

6. Material selection as needed: Different grades of alloys such as Hastelloy C-276, C-22, and B-3 can be selected according to the corrosion characteristics of the medium.
