Trenchless pipe rehabilitation
Rädlinger Primus Line GmbH is part of
the Rädlinger corporate group, which
has been active in the construction
sector for over 40 years.
The Primus Line
®
system was developed
to solve the recurring, time-consuming
and costly problem of run-down
pipelines in existing buildings.
Primus Line is a trenchless technology
for the rehabilitation of pressure
pipelines for different media such
as water, gas and oil. The process
is based on a flexible high-pressure
hose that is specially developed for
the system’s connection technique. Due
to its multi-layered structure and very
thin wall thickness, the Primus Line
hose provides both flexibility and high
strength material.
The inner layer of the hose can be
selected for the specific media. The
outer layer – regardless of medium – is
made of wear-resistant PE.
Between the inner and outer layers,
seamless aramid fabric functions as a
static load-bearing layer. The hose is
inserted into the host pipe from small
construction pits, thus avoiding large
roadworks. Primus Line is not stuck to
the host pipe, and is self-supporting
with an annulus.
At the ends, the Primus Line hose is
connected to the existing pipe (steel,
iron cast, PE or other materials), and
to the pipe network, via a specially
developed high-pressure connector.
Primus Line features short rehabilitation
times and fast recommissioning.

Expanded tool line for
easy, accurate tube
preparation
Swagelok has added five new tools to its
equipment product line to complement
its orbital welding equipment and tubing
offering.
Designed for portability and ease of
use, the expanded product selection
includes four new tube facing tools
and one cutting tool. The tools are
intended for use with
316 stainless steel,
carbon steel, titanium,
and most nickel-based
alloys.
The new tube facing tools
produce flat, smooth, square,
burr-free and chamfer-free tube
ends. Available in four different sizes,
the tools feature high-performance,
coated tool bits with two cutting edges,
built-in electronic speed regulation,
and a quick change collet system that
requires no tools to change sizes.
The new tools include TF16 for
preparation of thin-walled tubing from 3
to 25mm (
1
/
8
" to 1") OD, available in both
electric and cordless versions; TF24 for
preparation of thin-walled tubing from
3 to 38mm (
1
/
8
" to 1½") OD, available
in both electric and cordless versions,
including a 90º angle option; TF40 for
preparation of thin-walled tubing from 6
to 63mm (¼" to 2½") OD, also available
in both electric and cordless versions,
including an angled version; and TF72
– the largest size – for preparation of
thin-walled tubing from 12 to 114.3mm
(½" to 4½") OD, available in an electric
version.
The new TC72 tool is for cutting
thin-walled tubing and elbows up to
114.3mm (4½"). With an integrated
laser pointer to determine the cut-off
point and integrated clamping jaws
constructed from hardened aluminium-
cast, the TC72 is designed for easy tube
preparation with square and burr-free
ends.
More information, including catalogues
and user manuals, can be found on the
company’s website.
The tube facing tools and cutting tool are
available through authorised Swagelok
sales and service centres.
