When choosing Retractable Coil Tubing, there are several factors to consider. One of the most important is coil diameter, as the smaller the diameter the better the retractability. Another consideration is working length, usually measured in percentages of the total length of the material. For example, polyurethane tubing has a working length of 80-90% of the overall length, while nylon allows for a working distance of 67-75% of the total material length. In addition, coil length should be retracted (without pig tails) and outer diameter should be taken into account when determining retracted length.
PTFE
PTFE Retractable Coil TubING has a number of advantages. PTFE is an inert chemical, so it\'s resistant to corrosive environments. FEP and PFA can be used for a variety of applications, and the retractable coils are ideal for water-dispensing applications. The coils can be manufactured in a variety of lengths and widths, and the size of the tube itself is largely determined by the needs of the application.
PTFE Retractable Coil Tubs can be made from 316 stainless steel or a similar material. The wall thickness can range from 0.035 to 0.065 inches. The length can be up to two thousand feet, and the working pressure range is typically 2,625 psig to 10,475 psig. PTFE Retractable Coil Tubing is suitable for a variety of industries, including chemical, thermal, and instrumentation applications.
PTFE Retractable Coil Tubs are available in 12 to 72-inch lengths. They can withstand operating temperatures up to 400 degrees Fahrenheit. They also feature OD/ID ranges of 3/16 to 1/2 inches. Coiled FEP offers the same chemical insulation properties as standard FEP tubing. They are also FDA approved. The following are a few common uses for PTFE Retractable Coil Tubing
Fluoropolymer material is known for its excellent heat and cold resistance. In addition, it\'s virtually inert to industrial chemicals and solvents. Thus, PTFE Retractable Coil Tubing can handle virtually any corrosive liquid or gas. Besides offering these benefits, PTFE Retractable Coil Tubing is available in an extensive selection from NewAge.
Polyurethane
Polyurethane Retractable Coil Tubes are used in a wide range of medical applications. Their self-storing and retractable nature makes them perfect for a variety of uses, including pneumatic hospital beds. Polyurethane coiled tubing is a preferred material in these applications due to its exceptional memory, abrasion resistance, and resilience to overstretching. Polyurethane coils can withstand 140 psi and are easy to use.
Polyurethane Retractable Coil Tubes are available in 12 in. to 72 in. lengths and operating temperatures from -40°F to +400°F. The IDs are 1/16 in. to 3/8 in. They are non-sticky and feature chemical insulation properties identical to standard FEP tubing. Custom tubing can be manufactured in any size, shape, and color.
This type of hose can withstand extreme temperatures, and is ideal for conveying dry powders and gases. Polyurethane hoses are suitable for use in a wide range of applications, including pneumatic, fuel transfer, robotics, and industrial. They are extremely durable and are flexible, making them a superior choice for a variety of industrial and medical applications. However, polyurethane hoses are not suitable for drinking water, as they are more likely to transfer odours and tastes.
Another application of coiled tubing is in oil and gas wells. Its thin internal diameter helps lift liquids to the surface. Otherwise, liquids in the wellbore can collect and "kill" the well. However, they can be used in conjunction with conventional tubing and casing, in a procedure similar to wirelining. The space between coiled tubing and conventional tubing is called a micro annulus.
Coiled tubing is often used for deliquification and circulation. Circulating fluid is a safe solution to hydrostatic head, a problem that may block the flow of formation fluid. A gas is often added as a lubricant, such as nitrogen, which is commonly called \'Nitrogen Kick.\' Coiled tubing also allows for the cleaning of light particles in wells.
