Testing Procedures
McWane Poles pass through a series of quality control procedures between inbound scrap metal and
finished and bundled poles. The quality measures are broken into the following departments:
1. Scrap – The coke room operator inspects scrap in the scrap yard (W4.901-111) and complete Raw
Material Inspection Form (F4.901-132).
2. Melting (P4.901-120) – Iron is sampled for chemistry in the desulphurization ladle every 15 minutes
(W4.901-094) and analyze with a spectrometer (W4.901-109 & 110). Low Sulphur iron then flows
to the forehearth where it is again sampled (W4.901-082) every 30 minutes to determine chemical
composition. Based on the sample, the Coupala Operator will instruct the forehearth operator how
much magnesium and silicon to add to the iron ladle.
3. Casting
4. Post-Anneal Material Properties
5. Additional Material Properties Inspection – Hardness is inspected
6. Wall Thickness – Wall thickness is inspected every one foot with an ultrasonic thickness guage on all
sections.
7. Joint Overlap
8. Component an Cosmetic
In addition to these procedures, ongoing sampling of finished poles are taken as part of ASCE Manual of
Practice 111.
