HandyTube receives NORSOK qualification
from MRC Energy Piping
HandyTube has been successfully
qualified by MRC Energy Piping for its
6Mo (UNS S31254) seamless coil and
straight length tubing up to 3.8mm wall
thickness according to NORSOK M650
Edition 4 for MDS R18. The qualification
is an important milestone in HandyTube’s
commitment to being a valued supplier
and a key resource to the oil and gas
industry, providing custom solutions for
critical applications.
NORSOK is a set of standards
developed by the Norwegian petroleum
industry to ensure adequate safety,
added value and cost effectiveness
for development and operations in the
petroleum industry, and is intended to
supersede oil company specifications
and to serve as authorities’ regulatory
references. NORSOK M-650 verifies
that a manufacturer has sufficient
competence and experience producing
the relevant material and the necessary
manufacturing facilities and equipment
to support the production of the product
for the duration of the qualification
period.
To meet the qualification requirements
for NORSOK M-650 the purchasing
company, MRC Energy Piping, is
responsible for performing an audit
of the manufacturer. The results of
this audit demonstrate HandyTube
possesses the knowledge, equipment,
processes and procedures necessary
to repeatedly produce the required
finished products for use in critical
applications.
Upon completion of the audit MRC
Energy Piping and Handy Tube signed a
Qualification Test Record (QTR) stating
all qualification requirements have been
met. Each QTR is specific to a particular
alloy, production route, product form
and product thickness.
HandyTube manufactures seamless,
stainless steel coil and straight length
tubing, and is able to produce seamless
tubing upwards of 6,000 feet long, and in
custom sizes to best suit the application.

DVGW certificate for high-pressure
pipe system
The HexelOne® high-pressure pipe
system has been certified by the DVGW
for gas and drinking water applications.
The approved use of the plastic pipe
system in high-pressure settings pro-
vides two benefits that previously only
applied to low-pressure applications:
the corrosion resistance of the pipes
makes cathodic corrosion protection
redundant, and the system allows the
use of modern installation techniques
that shorten construction time.
The reinforcement opens new areas
of use for egeplast’s HexelOne, with
permissible operating pressures
of 30 bar for water and 16 bar for
gas, exceeding the range of
applications previously covered by PE
pipes.
The stability achieved by the HexelOne
pipe with its reinforcement layer of high-
strength PE strapping is claimed to
be twice as high as that provided by
PE-100 full-wall pipes.
Owing to their protective layer and inner
layer made of PE 100-RC, the pipes
are suitable for trenchless installation.
The DVGW certificate for drinking water
covers dimensions from d 90mm to
d 125mm. In addition, HexelOne gas
pipes have been certified for up to
d 160mm.
