Welcome to www.pretread.com your reliable single source for
neoprene bridge bearing,

lines and we hope you will find this very informative.
Modern day construction requires large span movements for
bridges, buildings and pipe lines and www.pretread.com has the
right solution for your for your Sliding Bearing requirements.
Especially in the newly developed Shopping malls and airports
where spans are very wide and structural movements are
over 100 mm plus or building amd structures in a seismic prone area with HDRB
(High Density Rubber Bearings)with movements even much
greater, effective and economical solution is to use our ptfe
sliding bearing combination with or without 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 Teflon sliding
bearing in combination with 316 Grade Stainless Steel mirror
finished surface as sliding top proves excellent sliding
control.Thickness of ptfe TEFLON sheets will be to AASHTO / BS / DIN / En 1337-2
specifications. We are proud to be the first one in the
Middle East in U.A.E.to provide such manufacturing facility, with
ptfe Teflon, there by high cost of import and time delay can be
avoided.

loads and Laminated Elastomeric Bearings with ptfe TEFLON Sliding
Tops for heavier load.
Pipe slides and Pipe supports
ptfe-Teflon and Stainless Steel Slide bearing plates are the only
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,valves and 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
pipe supports.
Our "pipe supports" are composed of two sliding elements, a
metal backing plate (sometimes manufactured out of Stainless Steel 316
mirror finish grade)or Carbon Steel plates with SS316
clading and a low coefficient of friction material
PTFE-Teflon, bonded to another metal backing plate. When pipe
supported by Ptfe-Teflon and Stainless Steel Slide bearing plates
moves (due to thermal expansion) it slide across surface of
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
environments.
Advantages of hot bonded dimpled ptfe-Teflon for pipe supports.
Dimpled Virgin ptfe -Teflon sheet is hot bonded to CS ( carbon steel )
base plates using proprietary hot bonding method at temperature of 160 º C
or above and at a pressure of 250 Kg /cm² which provides much higher peel-off
strength between CS plate and ptfe - long service life.
Surface irregularity formed during long term sliding movements
reported between SS plate and ptfe-Teflon under varying vertical load
seen in conventional pipe supports is totally avoided with dimpled
ptfe-Teflon with silicon grease - long service life.
High melting point Silicon grease applied between dimpled ptfe-Teflon
and top SS 316 plate will stay in dimples to provide a Lower friction
coefficient between ptfe - Teflon and SS316 - long service life.
Ptfe-Teflon offered will be of European origin with necessary
certifications - quality assurance.
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
supports.
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.
ATTACHMENT CONSIDERATIONS
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, burn or damage bonding between
low-friction ptfe Teflon and metal plate. A 15 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
such as:
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 ;
Generation Plants ; Nitrogen Production Plants
Please feel free to send us your requirements, and our
technical staffs are available to support you and answer your
queries on a 24/7 basis.
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 over 12 kg/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.
