Ultrasonic scanners
for line-pipe
SCANMASTER is a manufacturer of ultrasonic inspection systems
for a wide range of applications including pipe, aerospace, rolling-
stock and automotive applications.
Pipe scanners for ERW, SAW-H and SAW-L pipe include
configurations to test strip, weld, body and ends of the pipe in
online or offline condition. ScanMaster systems meet quality
standards such as API-5L, ISO-3183, DNV and EN.
ScanMaster’s scanners for the ERW pipe include strip, weld,
body and ends scanners for line-pipe with diameters from 2" and
up. Offline systems allow high scanning speed in the range of 1m/s
with excellent durability and uptime. Integrated weld and ends
testers can throughput more than 2 pipes/minute.
Scanners for SAW-H pipe include weld, body and ends scanning
within a single mechanism saving time and mill space. The scan
head for the helically welded pipe includes linear guidance of the
probes resulting in fast setup and minimal calibration time, while
allowing the maximal number of probes to be placed around the
weld. A weld tracker based on laser technology, also developed by
ScanMaster, may be integrated with the scanner.
Display and reports of the scanners include all the technical
and general information of the scanned product as well as results
listing and defect mapping. Displays of the scan A-, B- or C-scan
as well as customised mapping methods are included. Reports
can be automatically exported into common format files and
integrated with other industrial or information systems.

HSS-based saw blade
THE Swiss company SW Wil has developed a new kind of
HSS-based circular saw blade, the PowerBlade 65.
Using a HSS vapour blade it is possible to cut up to 380 N/
mm2 with a moderate cutting speed.
With a standard HSS blade and a common AlTiN PVD
coating users are able to cut up to 450 N/mm2 with a good
lifetime and cutting speed.
TCT saw blades are normally used above 650 N/mm2. For
the gap between 450 to 650 N/mm2 there was no circular saw
blade available offering an optimum solution for cutting tubes
and bars in this range.
SW Wil is now putting a complete new HSS saw blade on the
market with a special HSS body and a coating system featuring a
much higher oxidation resistance than any other one in the market.
The PowerBlade 65 is setting a new standard in the line between
450 to 650 N/mm2.
