What’s New in June
Starting this June, our popular line of Smooth-Tube hoses will now be in stock at our fulfillment center for more timely shipping! This will be a great help for those of you who need durable flexible ducting with smooth interiors. This is a very important development because smooth bore hoses are always in demand. Now you won’t have to wait the 3-6 week lead time that it usually takes to make a hose. The Smooth-Tube line of hoses is highly recommended for material handling applications. Thanks to the smooth non-corrugated interior, nothing will get caught or jammed inside the hose. These flex ducts will be readily available in ID sizes of 3”, 4”, 5”, 6”, 8”, and 10”. Take a moment to learn more about the three different versions of this hose.
Smooth-Tube PVC: This hose is made from a medium-weight clear PVC material. The body of the hose is ringed with a black external PVC helix that acts as a wearstrip. It is a popular choice because of its clear hose wall which allows the end user to see what is being transferred through the body of the hose. Since it is made with PVC, it features a good level of resistance to most chemicals.
Smooth-Tube TPR: Made with a black co-extruded thermoplastic material, this is an excellent hose for more demanding fume and abrasives transfer applications. Due to the fact that it is made with thermoplastics it has an operating temperature range of -60° F to 275° F, with the ability to take intermittent exposure to temperatures reaching up to 300° F. It is a fairly crush resistant hose too thanks an external wearstrip made of a rigid polypropylene compound.
Smooth-Tube PU: This version of the Smooth-Tube line of ducting is the most physically durable because it is made with polyurethane. The wall of the hose is semi-clear and the external part is ringed by a yellow wearstrip made from ABS. Both polyurethane and ABS are types of plastic used in situations where physical durability is an absolute must. This hose is very durable against sources of physical abrasions such as dragging, crushing, and puncturing. We recommend this hose for use in more heavy duty types of abrasive handling applications such as concrete transport, sand suction, and leaf vacuum just to name a few.
Ducting Basics: Hose vs Ducting
In the context of our product line, the words “ducting” and “hose” are often used interchangeably, but you should be aware that there are clear differences between the two. According to the standard definition, ducting is a system of pipes and tubes used for transferring a specific type of material, or media, from one location to another. The exact type of material can vary from air and chemical fumes to solid materials such as gravel and leaves. Keep in mind that in current industrial nomenclature, the term “ducting” is specifically meant for use with fumes and materials while “hose” is meant for the type of pipes that handle liquid. The two terms do get mixed together on occasion. It is rare to see ducting used in reference to liquid handling, but hose is often used to refer to applications that involve air and materials.
ID size is one of the key differentiating factors between hoses and ducting. ID stands for inside diameter and you can measure a duct’s ID by measuring from one end of the inside section of the wall to another. Hoses tend to be smaller in ID compared to ducts. Liquids do require higher degrees of pressure in order to be moved and smaller diameters help create the necessary pressure. Ducts, on the other hand, are found in much larger diameters because they need relatively lesser pressure in order to transfer air and materials. Some ducting is available in ID sizes that go up to 60”!
Tips To Remember Before You Buy
What is diameter?
Diameter is a very important unit of measurement when it comes to flexible duct sizing because all duct sizes are measured according to their diameters. Flexible ducting is normally sized according to the internal (or inside) diameter, often labeled as ID.
How do you measure the diameter of a round object? The diameter of a circle is the length of a straight line going from one side of a circle to the opposite side. To measure the diameter, simply choose two points on the edge of a circle that are directly across from each other, and measure the distance between these points.
Do not mistake circumference for diameter
A circle is a two dimensional shape made by drawing a curve that is the same distance all around from the center. Circles have many components including: chords, curves, diameter, radius, tangents, arcs, sectors, semi circles and central angle to name a few. It was Archimedes who developed the formula for determining the area of a circle.
The diameter of a circle is the length of the line through the center and touching two points on its edge. In the figure above, drag the orange dots around and see that the diameter never changes. The diameter is also a chord. A chord is a line that joins any two points on a circle. A diameter is a chord that runs through the center point of the circle. It is the longest possible chord of any circle.
Diameter: The center of a circle is the midpoint of its diameter. That is, it divides it into two equal parts, each of which is a radius of the circle.
Radius: The radius is half the diameter. Radius The radius is the distance from the center to any point on the edge.
Circumference The circumference is the distance around the edge of the circle.
Diameter = 2R
R is the radius of the circle where:
C is the circumference of the circle
π is Pi, approximately 3.142
