Standards Pipe Lenght
Standards Pipe Lenght
(OP)
Hi,
Is there any standards that talk about the recommended pipe lenght?
We sometime order piping segments to replinish stock, but the piping supplier very frequently replies that the size we ordered is not available, and therefore they offere a different lenght.

MeEn

RE: Standards Pipe Lenght
Why not ask the suppler what lengths he stocks - seems a reasonable request.

As noted in that site, lengths of 100 feet (~30 meters) or more have even been furnished at times in the past. For other applications e.g. water or wastewater, I agree pipe lengths in the 18-40 feet (5.5-12 meter)range or shorter are probably more common, for many reasons and different material types, relating to common constructions.
More information about your application/location and/or of course talking to your suppliers might help to confirm this better.

For example, section 17 of ASTM A106 stated:
17.1.1 The lengths required shall be specified in the order,
and
17.1.2 No jointers are permitted unless otherwise specified.
17.1.3 If definite lengths are not required, pipe may be
ordered in single random lengths of 16 to 22 ft [4.8 to 6.7 m] with 5 % 12 to 16 ft [3.7 to 4.8 m], or in double random lengths with a minimum average of 35 ft [10.7 m] and a minimum length of 22 ft [6.7 m] with 5 % 16 to 22 ft [4.8 to 6.7 m].
RE: Standards Pipe Lenght
I would say that double randoms are the most common for oil and gas pipeline work.

Correct - dbl randoms (12 meter/40')are most common in oil & gas work. For pipelines we'll double joint those (24 meter/80') when site conditions allow.
And actually triple randoms (18 meter/60') are the most effecient for pipeline installation from a pure installation standpoint - they do however cause some logistical issues that often push us to dbl randoms.
