US Steel Košice sro is a producer of flat steel products,
with an annual production capability of 4.7 million tons. It
is a subsidiary of the USS Corporation, a worldwide steel
producer with an annual output of 26.8 million tons.
In addition to a variety of sheet metal products, the company
also produces spiral welded pipes from structural and micro-
alloyed hot rolled steels.
The pipes are produced in accordance with several
internationally recognised standards. The entire production
process is continuously monitored, and pipe surface and
welds are consistently controlled by a series of non-destructive
PVC pipe takes off from Pipelife Jet Stream
A new PVC pipe made by Pipelife Jet Stream in the US has met with such a strong market demand that it has prompted a
substantial expansion in production capacity. Compared to conventional PVC pipes, the new product – C900 – is designed to
withstand extremely high hydrostatic pressure on testing. The PVC pipe acquired its name from the C900 standard laid down
by the ASTM, the US standards institute – a standard to which the new pipe complies completely. The company reports that
market response for its use in municipal water distribution, forced mains sewers and fire lines has been strong.
Scot McGuire, sales and marketing manager for the firm, explained: “Our blue pipe owes its superior performance under
pressure testing to increased wall thickness. As such, it can withstand four times its pressure class. Four, six, and eight inch
diameter versions are now being supplied and we intend to introduce a 12 inch version next year.”
Since its launch in April 2007, around 500 miles of C900 pipe have been manufactured at the company’s production facility
in Siloam Springs, Arkansas. They are delivered in twenty foot lengths and are easily butt-welded on site to secure jointing.
“PVC pipes have an expected lifetime of over 100 years,” commented Mr McGuire. “Furthermore, C900 has particular
resistance to internal and external corrosion. Municipal authorities throughout the US are therefore recognising its many
advantages.”

tests. The diameters of pipes range from 406mm to 1,420mm,
with wall thickness from 5mm to 14.2mm, and lengths from
8m to 18m.
Annual pipe production is approximately 90,000 tons.
Since the company started producing spiral welded pipes
in 1960, over 23,800km (14,800 miles) of pipes have been
produced.
The pipes are used mainly for gas distribution lines, crude
oil and water distribution lines, for district heating and
cooling systems, and for civil engineering and structural
purposes.
