What is a Paper Tube? Paper tubes consist of paper or paperboard sheet layers wound together to form strong, hollow, and usually cylindrical shapes. The paper layers are laminated or bonded together using adhesives. The wall thickness of the tube can vary depending on the number of layers wrapped during manufacturing. Paper tubes are also known as paper cores, paperboard tubes, paper cans, fiber drums, fiber tubes, paper tubing, wound tubes, composite cans, coreboard tubes, and cardboard tubes. While widely used everywhere, the term "cardboard tube" is a misnomer. Cardboard consists of three kraft layers with the central layer corrugated. Paper Tube Types and ShapesWhile paper tubes, paper cores and related products are all made from wound plies of paper or paperboard. Paper tubes or cores can be constructed from one, two or many plies of brown kraft paper or paperboard. The innermost layer or ply, the liner, and the outermost layer, the wrap, can consist of different materials (foil, film, etc.) or specialized paper. The specialized paper and materials can provide water resistance, graphics or labeling, or a specific color. The two main types of paper tubes and cores include spiral wound and convolute or parallel wound paper tubes. Convolute wound tubes are used in applications requiring high bend strength, crush resistance and dynamic strength. A spiral wound tube has the paper ply or plies wrapped around at an angle to the tube's axis. In convolute tubes, the outer two edges of the paper strip are wrapped parallel or at a 90-degree angle to the tube's axis. Paper tubes have thinner walls and are widely used as containers or packaging for products. A paper core is essentially a heavy-walled paper tube. The much thicker wall of paper cores enables their use in winding webs or sheets of flexible material into rolls in converting operations. Besides, a paper tube may require other accessories to help, such as Paper Angle Bead, Medical Tape Dispenser and Paper Stick Excpet for paper tube, another harder material is also widely used.

Indoor plumbing has been around for centuries. As many things change over the years, so has the type of pipes that maintain your plumbing. For instance, if looking at the plumbing system of older homes versus newer ones, you may find galvanized pipes in one and PVC tubing in the other. And for older homes especially, galvanized pipes are an outdated plumbing method and that should be replaced as soon as possible. Advantages of Using Plastic Pipes Long Life Cycle One of the best benefits of plastic water pipes is longevity. Unlike metal pipes that rust and corrode over time, plastic pipes will not corrode, rust, or develop sediment buildup that can lead to bursting. Plastic pipes feature a longer life cycle when compared to metal linesIn addition to its inability to corrode and long-lasting capability, plastic tubing also is fairly cheaper than the standard metal pipes. Especially in recent years metal, primarily galvanized steel or copper pipe prices have skyrocketed.Plastic piping is typically constructed with low-cost, light-weight material in a factory setting. Not to mention, it's also fairly easy to transport, thus making them cheaper to manufacture. Energy Efficiency When it comes to the installation of plastic tubing, PVC pipes don't need insulation which makes them far less likely to lose heat or experience unwanted heat intrusion. In addition, they're more resistant to sweltering summer temperatures or the brutal cold of the winter. This means that they don't need condensation as well. Easy to InstallSince you don't have to worry about insulation, plastic water lines are ultra-easy to install. Typically, a plumber in Trenton, NJ will need a CPVC primer or some form of plumbing cement to glue the pipes together. And in just a few minutes, your pipes are ready to go. Similar to repairing a plastic pipe, you may need to cut out the damaged section of the pip and replace it using a few couplers, which takes no time.[/url]
