Stainless steel HAGULIT® Connections

Stainless steel is corrosion- and heat-
resistant, meets high mechanical demands
and withstands chemical agents. Stainless
steel is an ideal material for long-term use
in aggressive waters.

However, even stainless steel can corrode
if the surface has not been properly trea-
ted or if the material grade is not properly
�t for the respective media. Appropriate
surface treatment of the �nished product
is essential to give stainless steel materials
the necessary resistance.

We only treat surfaces after all other
work has been completed (i.e. moul-
ding, cutting, welding). The pickling and
subsequent passivating is performed at
our own facilities or those of our partners,
using up-to-date techniques. This enables
us to ensure that our stainless steel pro-
ducts are of the utmost quality.

We stock all stainless steel grades nor-
mally used in well construction and are
pleased to assist you in selecting the right
material grade for your application.

Progressive technology and solid exper-
tise are the best guarantees for high-
quality products. Turnaround times are
also considerably reduced thanks to our
well-stocked inventory and our �exible
production arrangements.

The HAGULITfi coating is the result of our
own long standing research, driven by
our Client�s needs for well construction
products made out of steel and having
a nearly unlimited and maintenance free

Casings and screens are coated with an
especially developed epoxy-based pow-
der. The coating process is performed
using the �uidised-bed-coating process,
being a leading-edge technology. The
high qualities of the end products are en-
sured by monitoring all critical parameters
continuously during the coating process.

HAGULITfi offers the following

• Safe transport and installation due
to the extreme surface hardness of the
coating, hence high impact resistance.

• Increased temperature resistance for
use between -30 °C and +50 °C due
to high elasticity of the coating.

• Long-term resistance against most
cleaning and regeneration products
and procedures. The key to the
HAGULITfi coating�s premium quality
lies in the selected epoxy powder as
well as the pre-treatment of the steel

• Minimal oxygen diffusion through the
coating layer.

• Excellent coating adhesion due to
pretreatment by steelblasting.

• No below-coating rust or blistering.

The connector system ZSM (tension proof
push-�t socket) HAGUESTAfi and HAGU-
DOSTAfi minimise the installation time for
screens, casings and riser pipes in well

The amazingly simple connectors for
HAGULITfi-coated and stainless-steel
pipes make the system highly cost effec-
tive. After spigot and socket are �tted to-
gether effortlessly one or two splines have
to be inserted into the box of the socket.
This ensures a mechanically and hydrauli-
cally pressure tight connection. The time-
saving per joint boosts the economical
advantage especially in deep wells.

As an alternative to afore described con-
nection systems our pipes can be �tted
with round thread connectors or �anges
in accordance with DIN standards.

The disassembly of riser pipe columns in
case of pump maintenance is performed
as quickly as the original installation
procedure of the riser pipes.

In addition to sleeve connectors, our riser
pipes can be �tted with threaded connec-
tors or �anges, in accordance with DIN

For special applications,
rubber-coated riser pipes are also

The HAGULITfi coating offers the following
• Excellent adhesion
• High impact resistance
• Screws easily
• No below-coating rust or blistering
• Physiologically safe and chemically
resistant to wide range of agents

Stainless steel products, if properly
treated, will not rust and, depending on
the grade of steel, are also resistant to
substances in the surrounding media. The
�nal treatment of our stainless steel pro-
ducts is either carried out at our facilities
in Renchen, Germany, or by our experi-
enced partners.

At our site, the products are pickled in a
chloride-free process and subsequently
passivated with deionised water. This
system ensures consistent pickling both
for our own manufactured products and
those of our customers. If required, we are
able to pick up the un�nished products
and return them using our own �eet of
