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.
