What are industrial gases?
Industrial gases are gases that are used in various industries for processes such as welding, cutting, heating, and chemical reactions. They include calibration gases, bump gases, specialty gases, and rare gases.
What are calibration gases?
Calibration gases (cal gas or calgas) are mixtures of gases that are used to calibrate gas detectors, analyzers, and other instruments. They are typically used to ensure that the instruments are accurately measuring the levels of gases in the environment.
What are bump gases?
Bump gases are used to check the performance of gas detectors and to ensure that they are functioning properly. They are similar to calibration gases but are used for a quick check rather than a full calibration.
What are specialty gases?
Specialty gases are high-purity gases that are used for specific applications, such as in the semiconductor industry or in medical equipment. They are often used when the purity of the gas is critical to the process.
What are rare gases?
Rare gases are gases that are present in the atmosphere in small amounts, such as helium, neon, and krypton. They are used in various applications, such as in lighting and welding.
How are industrial gases stored and transported?
Industrial gases are stored in high-pressure cylinders or in cryogenic tanks, depending on the type of gas. They are transported by truck or by ship, and special precautions are taken to ensure their safety during transport.
How do I know which industrial gas I need for my application?
Our team of experts can help you determine which industrial gas is best for your specific application. Contact us to discuss your needs, and we will provide you with a customized solution.
How do I order industrial gases from your website?
Ordering industrial gases from our website is easy. Simply select the gas you need, choose the quantity and size of the cylinder, and proceed to checkout. We offer secure payment options and fast delivery.
Why do you have two search boxes on your search page?
The box on the left is to search by Part Number only (it can be a Portagas part number, ISC, BW, MSA, RKI, etc.). We have an extensive cross-reference list. The box on the right is to search by term (IE: 200 ppm NO).
My search yielded zero results... what do I do now?
Please fill out the online request form with as many details as possible (IE cylinder size, gas concentrations, etc.) or call or email us, and we are confident that we can get what you need.
What if I have a problem with my order or need to return a cylinder?
We are committed to providing excellent customer service. If you have any problems with your order or need to return a cylinder, please contact us, and we will assist you with the process.
What do I do when my cylinder is empty or expired?
Over 95% of our products arrive in green recyclable cylinders with the Portagas Strip and Ship™. Once the cylinder is empty or expired, simply peel the cellophane mixture label to expose the prepaid return freight label and hand the cylinder directly to the FedEx or UPS driver, whichever the label indicates.
Do you have a paperless option for SDS, COA, etc.?
Yes! As you are likely well aware, SDS can be 30-40 pages long, and it is not always convenient to be carrying them from job to job. We have a free Android or IOS phone app download that allows you to scan a QR code (unique to each cylinder) that has all of the pertinent information related to that cylinder (IE: Born-on date, expiration date, SDS (safety data sheets), COA (Certificate of Analysis), cylinder gas concentrations, expiration date, and NIST traceable lot number). Please reach out to us if you are interested.
What if my cylinder is “disposable” and not recyclable?
There are several methods by which you can properly dispose of these types of cylinders:
- Drill several holes to allow the remaining gas remnants to escape
- Purchase a special punch tool that sends the pin into the cylinder and allows the remaining gas remnants to escape
- Call a remediation company to pick up spent or expired cylinders. This is very costly and should be your last option
Note: Gas cylinders should never be thrown out when the regulator reads zero. There are still harmful and sometimes dangerous gases remaining in the cylinder.
