Lamination Joint
This is a restrained type of joint and can be used forFiber-glass Pipes.It is also known as Butt & Wrap Joint. The lamination joint is used to join plain-ended Pipe or Fittings sections. The process of a lamination joint is preparation of the pipe surfaces followed by of application of specific thickness of resin impregnated glass reinforcement is wrapped over a specific length around the pipes to be joined. The thickness and bond area of the lamination are related to diameter and pressure rating of the Pipe.

Chemical and industrial piping
Underground and above-ground pipelines
Repair and modification of existing pipelines
A Lamination Joint, also known as a Butt & Wrap Joint, is a restrained jointing method used to connect plain-ended FRP / GRP / fiberglass pipes or fittings. It involves wrapping resin-impregnated glass fiber reinforcement around the joint to achieve high structural strength and leak-proof performance.
Lamination joints are widely used in water transmission pipelines, oil & gas facilities, chemical plants, industrial piping systems, and underground or above-ground FRP pipelines where strong and durable joints are required.
Curing time depends on the resin system, ambient temperature, and site conditions. Typically, the joint is allowed to cure fully before pressure testing or commissioning.
