Why are fluorinated pipes and fittings so expensive? A DN100 fluorinated lining tee with a 6mm diameter costs over 600 yuan
The processing technique for pipes with a lining is very important; it’s not simply a matter of applying fluorine-based material to the metal pipe, but rather melting it and spraying it inside the pipe. The processing requires high temperatures, making it difficult, and since tetrafluoroethylene is also expensive, the cost of pipes with such linings is relatively high
@Valve Mingming, it’s from your store – it’s a bit expensive.
If you only consider the price, everything that costs money is expensive; for free options, you still expect someone to install them for you. The value of a product cannot be determined by its price, but by its worth.
There are costs involved in manufacturing as well; the production process for fluorinated pipe fittings is relatively complex, so high prices are normal. It’s just like cars: ordinary cars are cheap but not resistant to bullets, while bulletproof cars are expensive but provide safety.
Let’s find out how much PTFE and PFA cost per ton
Raw materials: PTFE is in powder form, while PFA is in granule form. Finished products: PTFE is white and opaque, while PFA is white and semi-transparent. Their heat resistance is roughly the same at -196/250; PFA has slightly higher heat resistance, at -196/260. When used as a lining, PFA offers better plasticity

Three-way connections are more difficult to manufacture than straight pipes; in addition, the manufacturing process plays a role, not just the material used itself
