RTRP stands for Reinforced Thermosetting Resin Pipe and FRP stands for Fiberglass Reinfoced Plastic Pipe. FRP is a composite material consisting of a thermosetting polymer, often a type of polyester, reinforced with glass or other fibers. Glass fibers provide strength and stiffness to a composite material. Different types of resins are used for the manufacturing of RTRP pipes, which are selected according to the required properties like chemical resistance, temperature resistance and mechanical properties. The properties of FRP pipes can be varied by changing the ratio of the raw materials. According to the type of resin used, FRP pipes can be classified as;
GRP - Glass Reinforced Polyester (Isophthalic resin) GRV - Glass Reinforced Vinylester (Vinylester resin) GRE - Glass Reinforced Epoxy (Epoxy resin) Lamination Joint This is a restrained joint system used for joining plain end pipes which consists of overlapping layers of fiberglass reinforcement thoroughly impregnated with the resin to achieve the specified width and thickness. It provides continuity in both hoop and axial directions. It is generally preferred for field adjustments and repair work where no other joint systems can be used. This joint is also called butt and strap joint and it results in high strength and requires skilled labor. Once the core pipe is laminated and tested successfully, jacket pipe cut to exact length to fit in the joint area is installed. This jacket pipe piece is laminated with the main jacket pipe by the same procedure. A nozzle is made on the jacket pipe to carry out the air test and subsequent injection of poly urethane foam. This type of joint is applicable for all the available pipe sizes

What are cold lamination machines?
Cold lamination machines offer an alternative method of lamination by using adhesives instead of heat. As opposed to traditional thermal machines, cold lamination machines are significantly less expensive and will not damage materials vulnerable to heat.
Can you weld nace pipe with non-nace pipe?
Welding should only be done between similar metals. Installing welded flanges to connect two dissimilar metals would be the preferred method of connection.
What is furnace butt welded pipe?
Furnace butt welded pipe refers to the manner in which a pipe is to be welded. The skelp itself is heated to a specific temperature in a furnace. You would then weld the longitudinal seam forge. This is a method that works on fence posts or pipes required for low pressure services.

What is rtr pipe?
Reinforced Thermosetting Resin Plastic (RTRP) Pipe.
What is deifference between GRE pipe and RTR pipe?
RTR Pipe(Reinforced Thermosetting Resin pipe) is a kind of composite thermosetting plastic pipe,combing Resin with Fiberglass Roving.In fact,the RTR pipe have a more approperiate name as GRE(Glass Reinforced Epoxy) Pipe, since that uses Epoxy Resin instead of Polyester.GRE Pipe have much superior properties than common RTR Pipe, especially in properties of high pressure resistant.
What is key lock joint in rtr pipe?
RTR pipe is Reinforced Thermosetting Resin Pipe (RTRP) or fiberglass pipe. A Keylock joint is a restrained joint, nylon rods (keys) slip into groove on the spigot and in the bell of pipe and restrain the pipe from pulling apart. The rods (keys) are removable.
