Struct PipeSize 

pub struct PipeSize {
    pub name: &'static str,
    pub threads_per_inch: f64,
    pub outside: f64,
    pub e0: f64,
    pub l1: f64,
    pub l2: f64,
}

One size of NPT.

Fields

name: &'static str

1/2: the nominal pipe size, in inches.

threads_per_inch: f64

outside: f64

The pipe’s outside diameter.

e0: f64

The pitch diameter at the small end of the external thread.

l1: f64

The hand-tight engagement.

l2: f64

The effective thread length of the external thread.

Implementations

impl PipeSize

pub fn pitch(&self) -> f64

pub fn height(&self) -> f64

The thread’s height, from its root to its crest: 0.8 P.

pub fn e1(&self) -> f64

The pitch diameter at the large end of the internal thread, where a hole is tapped from: E1 = E0 + L1 / 16.

pub fn diameters(&self, internal: bool) -> (f64, f64)

The major and minor diameters where a thread starts: an internal one at its large end, the face a hole is tapped from (E1); an external one at its small end, the pipe’s end (E0).

pub fn crest(&self) -> f64

How far the sharp V’s crest lies beyond the major diameter, in radius: half of what the truncation takes off.

pub fn designation(&self) -> String

How the thread is called: 1/2-14 NPT.
