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 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.
A Stainless Steel plate with ptfe - TEFLON sliding on top of it, provides a surface with a 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 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 environments.
Teflon and Stainless Steel provides lowest coefficient of friction for most combinations of temperature and load.
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 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. 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:
Liquefied Natural Gas (LNG) Plants ; Liquefied Natural Gas (LNG) Pipelines ; Liquefied Petroleum Gas (LPG) ; Steam Water Pipelines ; Chilled Water Pipelines ; Chemical Plants ; Polypropylene Plants ; Polyethylene Plants ; Power Plants ; Cogeneration Plants ; Nitrogen Production Plants
