FEP resin is pelletized for its hot-melt extrusion process. FEP tubing is known for its gas and vapor permeability properties and excellent UV transmission ratings. While very similar in composition to PTFE, there are a few notable differences. FEP has a lower heat shrink temperature and is more clear and flexible than PTFE.
FEP Tubing or coiled FEP tube used in applications ranging from environmental monitoring equipment to medical applications and electronics applications. FEP tubing is chosen usually require more clarity, flexibility or a lower heat shrinkable temperature than PTFE.
Hongda offers FEP tubing in a wide range of sizes and wall thickness to meet most of needs - from straight tubing and coiled FEP tubing. Corrugations or coiled FEP tube allow for a nearly zero bend radius and can be extended or compressed without affecting the tube's I.D.
A cost- and time-effective solution for well intervention operations employs coiled tubing. Instead of removing the tubing from the well, which is how workover rigs fix the problem, coiled tubing is inserted into the tubing against the pressure of the well and during production.
The coiled tubing is a continuous length of steel or composite tubing that is flexible enough to be wound on a large reel for transportation. The coiled tubing unit is composed of a reel with the coiled tubing, an injector, control console, power supply and well-control stack. The coiled tubing is injected into the existing production string, unwound from the reel and inserted into the well.Coiled tubing is chosen over conventional straight tubing because conventional tubing has to be screwed together. Additionally, coiled tubing does not require a workover rig. Because coiled tubing is inserted into the well while production is ongoing, it is also a cost-effective choice and can be used on high-pressure wells.
