Diamond-like Carbon has a coefficient of friction of as low as 0.05 on polished steel.
The larger the value of μ (aka Mu, the coefficient of friction, the greater the frictional force on an object. For instance, steel on nonlubricated steel has a μ of 0.58 while steel on lubricated steel has a μ of 0.06.
You need to know both material involved in the friction to find the coefficient

Use the "tan of the inclination angle" test.
Clean with emery cloth or a stainless steel tooth brush. lc
What kind of pipe, the inside or outside, or a tobacco pipe? If it is copper pipe, you can use an emery sand cloth or steel wool.
Grease reduces friction because the two original materials are no longer touching each other. If you have a piece of steel rubbing against another piece of steel then there is friction between them. If grease is on the surfaces then you have molecules of grease rubbing against other molecules of grease. Grease is slippery stuff as it has a very lowCoefficient of friction. Every material has a coefficient of friction but with steel it is quite high. Teflon is very very low. Proper name polytetrafluorethylene or ptfe.
it rubs the steel because its friction!
