Material certifications and test reports

Please remember that material certs and test reports are not avaiable for all items. Whenever you order material, regardless of who the supplier is, it is always good to request a material cert up front. Here at Component Supply, we do not always record our lot number when we pick an item for an order. This is something we try and do, but sometimes we wind up with “mixed” lot material from jobs. When we fill small quantity orders we may choose this material if the customer has not specified they require a material cert. So if that customer needs a cert after the fact, we would not be able to issue one. This is one scenario, but as a rule, you are always better to request the certs and other documentiation up front.

A Variety of Industries Use Hypodermic Tubing in Different Ways

Hypodermic tubing can be used in a variety of different ways to satisfy the requirements for pharmaceutical, medical device and industrial applications. One of the more common uses is to cut the tubing to the desired length, attach it to polypropylene luer hubs and turn it into blunt needle assemblies. Dispensing needles are used to ensure the accurate delivery of various fluids and liquids in the desired amounts. Many of the common gauge sizes in standard lengths are made available in lab assortment kits for organizations using a variety of different types.

Another use for hypodermic tubing is to use it along with straightened wire to create guide wire assemblies. For organizations requiring guide wire assemblies, you are able to obtain all of the tubing and straightened wire you require, and build them yourself, or take advantage of our customization services and let us build as many assemblies as you need. Just remember, if you are building your own assemblies, you will need the right tools to cut and deburr the tubing and straightened wire.

Additionally, some organizations have a demand for small cut lengths of this kind of tubing for certain manufacturing processes. Instead of having to cut the tubing yourself, or use secondary finishing and customization services, we offer a stock of one, two and three inch lengths, already cut, deburred and cleaned. Further, should you require one or two inch lengths with a 90 degree bend, you are able to find these sizes in stock and available for shipping. For other customizations, all you have to do is let us know your specifications, and we will work with you to deliver the tubing you require.

Nylon Mesh Screen Needs to be inspected on a Regular Basis to Ensure Its Durability

The durability of nylon mesh screen depends upon the materials it is exposed to, as well as the environment where it is being used and the temperature levels. Because there are different factors which influence how long the mesh will last, it is always a good idea to perform regular inspections of all of your screening before beginning your operations. You need to look for signs of normal wear and tear, including fraying of the nylon, damaged or torn openings, and the amount of sediment, dirt, or other debris in the openings and on the screen.

Factors which have a direct effect on the condition of your mesh include light exposure, weather conditions, exposure to alkalis, acids, solvents, and abrasive substances, as well as the dryness and humidity present in the surrounding air. Not all of these factors may apply, depending on how you use mesh screening for your applications. For example, you might only use the mesh indoors in a controlled environment and only need to worry about the types of substances you use with the mesh.

In situations where the nylon mesh screen is used for filtration, you should still set regular maintenance and cleaning intervals. The frequency of your intervals does depend upon the kind of filtration system in use. Single stage filters require more regular inspections than multi-stage filters, because a single stage filter collects all particles, sediment and dirt, using one piece of mesh. In either type of system, the screen can be removed, cleaned, and replaced back into the filter, and then used until it shows signs of wear and tear.

Many Different Industries Have Uses for Blunt Needles

Blunt needles are used in other industries and fields, in addition to medical applications. Industries, including automotive, electronics, henna art, food production, pharmaceutical, and manufacturing, all have their own purposes for using these kinds of needles in the workplace. They can be used to control the delivery of fluids, water, liquids, and viscous materials in the desired amounts. By attaching the needles to syringes, or bottles with measurement lines, organizations are able to control production costs and reduce waste expenses. Additionally, they are able to be attached to certain types of automated machinery where the equipment measures and controls the delivery amount.

For example, applying adhesives to different parts during a production process requires the precise amount is used. Using too little can result in the parts falling apart, later on. On the other hand, using too much adhesive could damage surrounding parts or components and prevent the product from performing as expected. In either case, quality of the finished good would not meet standards, and either has to be taken apart, or end up as waste.

In addition to the standard lengths available in blunt needles, you are also able to utilize secondary finishing operations to have needles custom finished to fit your own requirements. Customizations might include cutting hypodermic tubing to a longer length, having it deburred and cleaned, and then attaching it to polypropylene Luer hubs. You may also require a specific curvature or angled degree applied to the tubing in order to create needles used for accessing hard to reach areas.

Build Your Own Multi-stage Filtration System Using Woven Nylon Mesh

Building a decent filtration system should include the use of woven nylon mesh. This material comes with different-sized openings for removing particles, sediment, and dirt from fluids and water. By obtaining it in a variety of sizes, you are able to build a multi-stage filtration system. A multi-stage filter performs better and requires less maintenance than a single stage filter.

In order to design a multi-stage filtration system, you are going to require several different opening sizes of woven nylon mesh. You should place the mesh with the largest openings in your filter at the first stage. Further, you need to allow some space in between the first layer and second layer, for the water to be able to flow freely, as well as to have space to collect smaller particles. The second stage is where you will place the mesh with the next-smallest-sized openings. You repeat this process for however many stages of filtration you require. Your last stage always uses the mesh with the smallest openings.

As water or fluid passes through each stage of your multi-stage filter, the mesh only allows particles to flow through if they are smaller than the actual openings. For instance, at the first stage, the largest particles and sediment are removed. Then, at the second stage, slightly smaller particles and sediment are removed from the water, and so on, until reaching the final stage. Because each stage only collects particles and sediment larger than the mesh openings, the filter will operate for a longer period of time before having to clean each filter stage.

Things to Know about Thin Wall Stainless Tubing

Things to Know about Thin Wall Stainless Tubing

There are several advantages, and one concern to be aware of, when using thin wall stainless tubing, depending upon your applications. For instance, this type of tubing does help improve fluid flow rates any time you are working with a variety of liquids. Because the inside diameter is slightly larger than regular wall, fluids are able to pass faster from one end to the other. Delivery rates can be adjusted using different approaches, including reducing the amount of pressure placed on the fluid, or using a longer section of tubing.

Another advantage to using thin wall stainless tubing is it makes it much easier to pass viscous materials through the tubing. Any type of material which is sticky, thick, or greasy may get clogged or stuck in regular walled tubing. But, again, because the inner diameter is larger, these materials are able to be moved through the tubing easier and help avoid them from becoming clogged.

The main concern you need to know about has to do with bending the tubing to a desired angle. Because the wall is thinner than regular walled tubing, extra care has to be taken to prevent breaking or crimping the tubing. Often, it is recommended for this type of secondary finishing operation to use regular wall tubing in the desired inner diameter opening by switching to a different gauge size. In the event you must use a thin wall and require it bent, just remember it can take longer to complete this process, as special care is needed to maintain the integrity of the tubing.
