Threadless copper pipe, often referred to as TP pipe, is a seamless copper pipe material manufactured to the requirements of ASTM B **2 - Standard specification for Threadless Copper Pipe, Standard Sizes. This pipe may be manufactured from either of two alloys, C****0 or C****0 with C****0 being the most popular. Both of these alloys are composed of copper (Cu) concentrations in excess of *9.9% thereby making this material an almost pure copper product. Threadless copper pipe (TP) is manufactured in drawn temper (hard) only and is furnished in H*8 temper in nominal or standard sizes ¼" through *2". The outside diameter of threadless copper pipe (TP) is essentially the same as schedule *0 pipe, although the wall thickness is much less than that for the same size pipe. The available lengths for threadless copper pipe is *0 foot for sizes ¼" to *0" with *2" being furnished in *5 foot lengths.

Threadless copper pipe (TP) is required, by the standard, to be identified by a gray colored stripe throughout its length that contains the manufacturers name or trademark, the nation of origin and "TP". It is further required to be incised at intervals not less than 1½ feet with the manufacturers name or trademark and "TP" throughout its entire length.

Threadless copper pipe (TP) is usually joined by brazed socket-cup type fittings or socket-cup type flanges. It should be noted that standard copper pressure fittings of the B*6.*2 or B*6.*8 type are not compatible for use with TP pipe.
