Plastic Fluoropolymer PFA Heat Exchangers Specially For Circular Tank Operation

Plastic Fluoropolymer (PFA) Heat Exchangers Specially For Circular Tank Operation

Teflon is called Polytetrafluoroetylene in English, which is short for Teflon, PTFE, F4, etc. Because of the pronunciation, it is often called Teflon, Teflon, Teflon and so on. Teflon has comprehensive advantages that other materials can not compete with, especially its temperature characteristics and corrosion resistance in heat exchangers, which makes Teflon heat exchangers widely used in corrosion-resistant industries, such as chemical industry, pickling, electroplating, medicine, anodic oxidation and so on.

Teflon heat exchanger has excellent corrosion resistance and aging resistance. Because of its excellent temperature resistance, it is suitable for both steam heating and hot water heating.

Teflon heat exchanger is a new type of corrosion-resistant heat exchanger developed in recent ten years. The main results are shell and tube type and immersion type. It has unparalleled chemical and thermal stability (- 250 - 260 C). The tubesheet and bundle of F4 heat exchanger (3-10mm capillary) are sintered by advanced powder metallurgy process, with excellent performances. Through unique and advanced welding method, the connection strength between tube bundle and tube sheet of Teflon heat exchanger reaches 1.5 Mpa.

Teflon heat exchanger has excellent corrosion resistance. Because Teflon is an inert chemical material, it can work in almost all media except elemental fluorine at high temperature, molten alkali metal, chlorine trifluoride, uranium hexafluoride and perfluorinated kerosene. For example: concentrated hydrochloric acid, hydrofluoric acid, sulfuric acid, nitric acid, phosphoric acid, acetic acid, oxalic acid, caustic sodium, sodium hypochlorite, naphthalene, benzene, xylene, acetone, Aqua regia, chlorine, toluene, various organic solvents, etc.

Teflon heat exchanger has good scale resistance. Due to the chemical inertia, smooth surface, winding and high expansion coefficient of PTFE tubes, it is difficult to scale the heat transfer surface, which greatly reduces the number of equipment maintenance and ensures relatively stable heat transfer coefficient and long-term operation of production.

Teflon heat exchanger has good heat transfer performance. Because the heat exchanger is a thin-walled tube with a wall thickness of only 0.5 mm, 0.75 mm and 1 mm, the shortcoming of low thermal conductivity of Teflon material is overcome, and its total heat transfer coefficient can reach 150-300 (W/m2.K).

The resistance of Teflon heat exchanger is small. Because of its small friction coefficient, low roughness and excellent lubrication performance, the resistance of the fluid in the tube bundle is smaller than that in the metal tube bundle; the Teflon heat exchanger is small in volume, light in weight and compact in structure.

Q: Do you manufacture your products in house?
A: Most of our products are manufactured in-house at our factory.Some accessory items are not.
Q: Can I get the riser on my L-shaped aquaculture heater longer/shorter?
A: Yes.There is no price difference for making a heater with a middle riser,but there maybe a cost adder for a longer riser.
Q: What Third Party Approvals do your products carry(CE?)
A: Almost all of our products are CE compliant.
Q: How late can you ship?
A: Normally 7 days after comfirmed the order.

PACKING & SHIPPING
In our company,various packing methods are adopted according to different product features,such as carton boxes,wooden case etc.For electroplating plant equipment ,we can discuss it together and choose the most suitable one.
As for shipment,different ways have their own advantage and disadvantage:
By sea: the cheapest,suitable for large amounts,but take more time
By Air: faster, more convenient, expensive
By Express: more flexiable, door to door, expensive
