Introduction

The requirements on OCTG pipe

products have been constantly

rising due to advanced exploration

techniques like hydraulic fracturing

or horizontal drilling. Seamless tubes

(e. g. for risers or drill pipe) are usually

tested for ﬂaws on the outer and

inner surface and for inside wall

defects. As well wall thickness- and

dimensional measurement (GEO)

takes place. GE´s rotary testing

machines are the optimum solution

to fulﬁll the required test task on

small to medium diameter ranges,

representing a compact solution that

can be integrated directly into the

production process. Beside seamless

tubes, electrically-welded tubes (ERW)

having ﬂash-trimmed weld seams

are also tested on rotation units if

the later tube application speciﬁes

a corresponding test.

Test procedure The tubes are transported to the testing machine via linear roller conveyors having speeds up to 120 m/min. The tests are normally carried out in single tube testing mode but it is also possible to test in continuous end-to-end testing mode to reduce the untested ends and to increase the productivity. Several triple or double roller drivers overtake the guidance and the constant transport of the tubes directly in front of and behind the rotation mechanics.
