lines and we hope you will find this very informative.
Modern day construction requires large span movements for
bridges and buildings and pipe lines and www.pretread.com has the
right solution for your. Especially in Shopping malls and
airports where spans are very wide and structural movements are
over 100 mm plus or a building in a seismic prone area with HDRB
(High Density Rubber Bearings) are used with movements even much
greater, effective and economical solution is to use our ptfe
sliding bearing combination with laminated neoprene elastomeric
bearing. Both rectangular and disc type bearings can be supplied
with ptfe TEFLON top.
TEFLON sheets are used as sliding top surface to
manufacturing PTFE sliding
bearing in combination with Stainless Steel mirror
finished surface as sliding top proves excellent sliding
control.Thickness of ptfe TEFLON sheets will be to AASHTO / BS / DIN
specifications. We are proud to be the first one in the
Middle East U.A.E.to provide such manufacturing facility, with
TEFLON, there by high cost of import and time delay can be

Pipe slides and Pipe supports
Ptfe-Teflon and Stainless Steel Slide bearing plates are a
very practical and cost-effective way of providing a smooth
movement of mechanical systems for pipe slides and pipe supports.
From www.pretread.com we manufacture and supply ptfe slide
bearing plates consisting of Ptfe-Teflon and Stainless Steel for
a variety of applications including support of piping, heavy
equipments, pressure vessels, and structural steel members.
Concept of Ptfe sliding bearing is a Stainless Steel plate
with mirror finish slides on top of ptfe - TEFLON sheet which
provides a surface mating with low coefficient of friction as low
as 0.05 which can be attached to a supporting structure and this
combination provides support as well as simultaneously allowing
load to move (slide) freely along supporting surface.
Sandwich concept is used when applying slide plates for ptfe
Our "pipe supports" are composed of two sliding plates, a
metal backing plate (manufactured out of Stainless Steel 316
mirror finish grade) and a low coefficient of friction material
PTFE-Teflon, bonded to another metal backing plate. When a pipe
supported by Ptfe-Teflon and Stainless Steel Slide bearing plates
moves (due to thermal expansion) it slide across the surface of
the bearing plate without contacting the steel beam or supports.
Top half of Ptfe-Teflon Stainless Steel Slide bearing plates is
bonded to pipe, and bottom half to steel beam supports. We
recommend using ptfe - Teflon and stainless steel as both resist
oxidation and long services even in stressful, dusty, hostile
Size and thickness of ptfe sliding bearing and pipe supports
can be designed to your requirements once data on vertical load,
and horizontal movements are provided to us.
Teflon and Stainless Steel provides lowest coefficient of
friction for most combinations of temperature and load for pipe
Heavy duty Skid Pad Shoes
Our heavy-duty pate skid pad shoe is utilized in moving heavy
equipments and fabricated structures by sliding over skid ways.
Heavy duty dimpled and filled ptfe is used to manufacture these
skid pad shoes. Skid pads can be welded to bottom of structure
and can be used to slide heavy structure on polished wooden
planks or steel plates. Dimpled ptfe is bonded to metal using our
special boding DSTech Polymer compound to Enhance maximum bonding
between metal to ptfe. Dimples in ptfe retain lubricating
greases, which brings down friction between ptfe and sliding
surface into meager levels.
Welding is most common method of attaching slide-bearing
plate to supporting metal structures as pipe supports. When this
approach is used a "lip" must be built since extreme temperature
generated from welding may break or damage bond between
low-friction material and metal plate. A 6.00 mm "lip" is
adequate for most welded installations. Areas where welding
cannot be used (for safety or other reasons) bolting is most
common substitute in ptfe pipe supports. Slide bearing plates and
pipe supports are components of products for bearing system for
buildings and bridges, and as a result, we have extensive
experience in bonding Teflon and Neoprene to metal plates.
Our Ptfe-Teflon Stainless Steel Slide bearing plates and pipe
supports can be applied for a variety of different applications
Liquified Natural Gas (LNG) Plants ; Liquified Natural Gas
(LNG) Pipelines ; Liquified Petroleum Gas (LPG) ; Steam Water
Pipelines ; Chilled Water Pipelines ; Chemical Plants ;
Polypropylene Plants ; Polyethylene Plants ; Power Plants ;

Bonding advantages offered by DSTech Polymer Compound.
Our tested and proven DSTech Polymer Compound, a
combination of high strength synthetic resins, especially
developed for bonding ptfe to neoprene or to Steel surface is
used with Ptfe sheets to bond for ptfe sliding berings as well as
pipe supports. DSTech Polymer Compound provides higher bonding
strength as well as hardness, which maintains a rigid flat surface for ptfe to work
with-out buckling under sliding pressure, which is
normally seen with Conventional bonding system.We offer bonding
strength of 7kg/cm between ptfe and steel as well as ptfe and
neoprene.Bonding is normally done by hot vulcanization process
but resin bonding can also be offered.
