We offer precise real-time monitoring, mobile alerts, and predictive usage — reduce runouts so you have fewer costly, last-minute deliveries, even during critical pipeline commissioning and integrity testing projects.
Get your first delivery within 48 hours in California or Arizona.
We are proud to offer standard next day delivery, same-day delivery, and available 24/7 monitoring.
From the first walkthrough to delivery and beyond, our team is always ready to serve.
Our gas experts walk through your setup to build systems that prioritize safety and efficiency.
No matter the volume or type of gas, our state-of-the-art labs and highly-skilled production teams deliver.
Our drivers consistently perform in high-pressure environments and champion things such as customer care, road, and onsite safety.
Stop paying rent on cylinders that aren’t in your possession. And enjoy sustainable service with less deliveries thanks to telemetry’s mobile alerts, real-time measurements, and usage trends.
The days of chasing invoices and updating billing info are gone — access your account and re-order with confidence (and ease).
With WestAir cylinder tracking only pay for the cylinders that you are using. Never overpay for storing empty unused cylinders ever again.
Learn more about the different gases commonly used for pipeline services.
N₂
Used for purging pipelines of air, moisture, and hydrocarbons before commissioning, during product changeovers, and prior to maintenance and repair work. Also used for pressure testing and leak checking newly constructed pipelines.
CO₂
Used as an alternative purging gas in some pipeline commissioning and decommissioning applications, particularly where nitrogen availability is limited.
O₂
Cutting and welding during pipeline repair, construction, and maintenance operations.
Ar
Shielding gas for TIG welding of high-quality pipeline welds, particularly for stainless steel and high-alloy pipelines used in corrosive or high-pressure service.
He
Tracer gas for highly sensitive leak detection during pipeline commissioning and integrity testing, often used in combination with nitrogen.

Nitrogen (N₂) — The undisputed highest-volume gas in pipeline services by a wide margin. Nitrogen is used at virtually every stage of the pipeline lifecycle — purging and inerting during commissioning, pneumatic pressure testing, drying pipelines after hydrostatic testing, inerting during hot work and repairs, powering pneumatic controls and instrumentation, and purging during decommissioning. No other gas comes close to its breadth of application across the industry.
Helium — Niche in volume but critically important and irreplaceable for pipeline leak detection and integrity testing. No other gas matches its sensitivity for identifying micro-leaks in welds, seals, and pipe joints. Its high value and specialized role make it a premium, high-margin product for gas suppliers serving this industry.
Yes. We offer real-time monitoring for most of our gas applications to make sure you never run out. Our solution provides you (and us) with accurate updates on your levels so we can optimize your gas delivery, detect leaks and other issues – saving you money while supporting our sustainability commitments.
Yes. We make true same-day deliveries with no qualifications. If you call at 4:55 pm and you need a same-day delivery, we will deliver that day.
We offer cost-effective bulk gas solutions including bulk nitrogen and helium for pipeline companies. Your products will be safely delivered by our modern fleet of fuel-efficient trucks, equipped for cylinder and bulk gas delivery.
