Process Description CASTING
Copper cathode is heated to melting point then cast into copper billets in a modern remelt
and casting facility. Precise control is maintained over metal composition and billet quality is
assured by skilled casthouse and on-site laboratory personnel.
EXTRUSION
A 3,500 tonne hydraulic extrusion press converts the solid copper billets into long tubular
"shells" by forcing the preheated billet through a die and over a piercing mandrel. Crane
Copper Tube production and engineering excellence has resulted in innovative extrusion
techniques which produce shells of superior dimensional and compositional uniformity
enabling subsequent cold drawing to finished dimensions with precise tolerances.

DRAWING
Cold drawing of the shell is carried out on an extensive array of specialised equipment.
Specially designed cold drawing machines called "bullblocks" economically produce large
quantities of thin-walled tube whilst larger diameter and thick-walled tubes are rapidly
produced on multi-die "drawbenches". Close supervision by process operators and staff
ensures tube of the desired dimensional and mechanical properties.
FINISHING
The cold-drawn tubing is conveyed to "finishing lines" which manipulate and cut the tube to
produce a product of the required form and length. All tube is inspected for defects using
on-line eddy current analysis which ensures that only flawless tube is packed and shipped
from the mill.

ANNEALING
The temper of some tube is modified using annealing ovens which maintain strict control over
temperature and furnace atmosphere resulting in product without discolouration and with
those mechanical properties desired by the customer.
LAGGING
Copper tube is fed through a specially designed cross-head plastic extruder which applies a
plastic coating in plain or castellated form. This provides the customer with a cost effective
prelagged copper tube.

ASTM B88 : 99 (Copper Water and Gas Tube)
This specification covers hard drawn temper, seamless copper tubes which are suitable for use in general plumbing applications,
such as underground water service, potable water distribution, gas distribution and fire sprinkler installations.
To assist with selection this standard is separated into three Types - K, L and M. Each type is differentiated by a range of wall
thicknesses, with Type K having thicker walls than Type L, and Type L being thicker than Type M, for any given diameter.
