Nippon Sanso Matheson in Houston, Texas prides itself on industry leading customer service. At our Houston location, you are never dealing with a call center. We have been part of the Harris County community for many years, and we welcome your call, question, or visit to our store. We have a very experienced staff. We will take the time to help you find the right welding machine, the right filler metal, gas – whatever you need to get the job done. Whether you are a home hobbyist or in one of the industries we support every day, we welcome your partnership and we never take you for granted. At Nippon Sanso Matheson, we take safety seriously and are proud to have won a CGA award in 2025 for our track record of making deliveries safely. Our cylinders are inspected and we meet and exceed DOT standards.
Construction and Contractors:
Nippon Sanso Matheson knows contractor, refinery, and infrastructure work. We understand the intense pressure and tight timelines faced by specialty, mechanical, electrical, structural, civil, and general contractors. Whether you are managing high-stakes refinery turnarounds, large-scale data center developments, road construction, or energy infrastructure like renewable fuels and carbon capture projects, we know that downtime is costly. That is why we pride ourselves on exceptional responsiveness—offering same-day or next-day gas delivery, local Houston-area ties for emergency services, and the robust supply network of a major national provider to keep your projects strictly on schedule from groundbreaking through final commissioning.
Our comprehensive supply capabilities span industrial, bulk, and specialty gases—including oxygen, nitrogen, argon, carbon dioxide, helium, hydrogen, EPA protocol mixtures, and liquid gases for concrete cooling. We provide high-purity nitrogen for moisture-free purging and precise pressure testing, alongside complete welding solutions like shielding gases, custom-length weld leads built at our Houston store, and mill-certified and/or nickel-based TIG rods. To equip your crew from the fabrication shop to the jobsite, we also stock essential tools and safety gear, ranging from pipe fit-up tools, bevelers, and grinders to FR gear, coveralls, Z87+ goggles, and hardhats.
To help customers easily manage multiple complex jobsites, we streamline backend operations by tracking every rental cylinder by barcode and serial number, simplifying purchase orders and eliminating costly “loss of use” invoices during jobsite closeouts. From local Harris County fabrication shops to multi-phase national infrastructure projects, Nippon Sanso Matheson delivers the technical expertise, cryogenic systems, and reliable supply chain needed to improve weld quality, optimize cutting operations, and ensure successful project execution.
International Gas Needs:
Are your gas needs international? Nippon Sanso Matheson has the experience and resources to support your international needs. Whether you are exporting or importing from Houston, we can help with helium in liquid form, ISOs or tube trailers. We can help with specialty or high purity gases, or whatever gas you need. We are able to work with you in English or Spanish, and we are familiar with the needs of our exporting customers.
Welding and Metal Fabrication:
Our sales reps certify as AWS Certified Welding Sales Representatives, because we know how important it is that you can rely on your sales representative for expert advice on your welding application. We supply all the major manufacturers of welding supplies- visit us in Houston, TX in Harris County for your Lincoln Electric welder needs, Miller Electric welder needs, Hypertherm plasma cutting machines, and others. That includes a wide assortment of welding wires and filler metals- and our staff has the expertise to help you understand the AWS nomenclature, strength and other properties of each.
If you are looking to upgrade your cutting operation to a laser cutting table we can help with that as well – we have a partnership with a leading manufacturer of laser cutting tables, and can also support you with the assist gas needs, nitrogen, oxygen or a mix.
Healthcare & Life Sciences:
Your patients trust you, and you can trust us. Whether you are installing a bulk oxygen system at a hospital, or need small medical cylinders at a dentist’s office, we have single source accountability as you are working with the producer and filler of the gas – not just a reseller. For our customers doing life science, scientific research, or freezing biological specimen, we can help everything from with liquid nitrogen, cryogenic freezers to vacuum jacketed piping.
Our medical gases are filled and stored securely in accordance with all applicable regulations. We are familiar with the strict compliance standards and emergency planning that large hospitals require. We have over 30 FSSC Certified and FDA registered ASUs for food grade nitrogen and over 30 medical ASUs registered with the FDA. Our ASUs manufacture Oxygen, USP and Nitrogen, NF under Good Manufacturing Practices following approved procedures which are in alignment with 21 CFR Part 213 and CGA M-2 Standard for the Manufacture of Designated Medical Gases.
