Why do you flare copper tubing?

During assembly, the flared end of the copper pipe is secured to the tapered fitting by the flare nut. It allows for leak-tight and pressure resistant seal. The two parts of flare fitting, the flare nut and the actual flare fitting, should fit easily together.

How do you flare a stainless steel brake line?

How to Correctly Flare Stainless Steel Tubing for either 37° Single Flare and 45° Double Flare. We recommend that you start by cutting the stainless steel tubing with a 32 tooth per inch saw (See Figure 1). A tubing cutter or die-grinder, will "work harden/heat treat" the material and make it brittle and prone to crack

How do you anneal stainless steel tubing?

Yes it is possible to anneal Type 441 stainless steel tubing. Full annealing is performed by heating to a temperature between 760 and 830 °C for 90 minutes per 25 mm of thickness, followed by air quenching. Stress relieving, e.g., after welding, can be performed in the range of 200-300 °C.

Why are some brake lines coiled?

Brake lines are coiled to prevent breaking from fatigue due to moving parts. The mounting points on components which move relatively to each other due to movement from vibration, heat, etc. need to have some relief, as in a coil or flexible line. So they wrap wire around the brake lines to help with flex?
