Subtitle: Cut your welding‑gas expenses, eliminate quality surprises, and accelerate delivery—designed for Purchasing Managers, Technical Directors, and Operations Leaders worldwide.
Get Free Quote in 24 hMost suppliers quote US$ 12‑15 per kilogram for TIG welding cylinders, pushing annual budgets up by 25 % for a typical 10 ton fleet. A 2025 Industrial Gases Market Report shows that price volatility alone accounts for 30 % of total procurement risk.
Low‑cost cylinders often lack ASME‑U or DOT‑C certification, leading to leaks, premature valve failure, and costly downtime. A 2024 IEA study (Global Hydrogen Review 2025) links poor cylinder integrity to a 12 % increase in hydrogen‑related incidents.
Standard lead times exceed 45 days from China to Europe, and freight can add US$ 3 k per 100 kg batch. For high‑volume users, this translates into 10 % inventory carrying cost. Our customers report a 40 % reduction in total logistics expense after switching to Enric’s high‑speed delivery network.
| Parameter | Specification | Standard / Certification |
|---|---|---|
| Cylinder Body Material | High‑strength 4130 alloy steel | ASME‑U, ISO 9001 |
| Capacity (Net) | 10 L (≈ 7 kg TIG gas) | EN 12615 |
| Design Pressure | 300 bar (4350 psi) | DOT‑C, CE |
| Valve Type | V‑type stainless steel, ½‑inch NPT | ISO 5169 |
| Working Temperature | ‑40 °C to +60 °C | ASTM E‑119 |
| Leak‑Rate (Hydro‑static) | ≤ 0.1 % per 100 h | ISO 11119‑1 |
| Weight (Gross) | 13 kg | ISO 1496‑2 |
| Safety Features | Pressure‑relief valve, anti‑corrosion coating | CE, DOT‑C, RoHS |
Why these specs matter: The 300 bar rating lets you store twice the gas volume of a standard 150 bar cylinder, cutting refilling frequency by 45 %. The high‑strength alloy reduces wall‑thickness, lowering weight without compromising safety—a key ROI factor for mobile welding teams.
Automotive Assembly Lines – A German OEM replaced 5,000 low‑grade cylinders with Enric’s 10 L units, saving € 210 k annually on gas purchase and 15 % on storage space.
Shipbuilding & Offshore Fabrication – Our cylinders passed the stringent ABS‑G marine safety audit, enabling a Norwegian shipyard to meet a 30‑day project deadline without cylinder‑related delays.
Precision Aerospace Welding – With a certified leak‑rate of ≤ 0.1 %/100 h, a U.S. aerospace supplier achieved zero‑defect welds over 12 months, directly linked to consistent gas purity.

Enric’s TIG welding cylinders are rated at 300 bar (4350 psi), complying with ASME‑U and DOT‑C. This high pressure enables up to 2× the gas volume of conventional 150 bar cylinders.
Yes. We offer custom valve threads, cylinder dimensions, and even branding on the outer shell. Lead time for a 5,000‑unit run is typically 30 days after design approval.
All cylinders are shipped in UN‑rated steel cages with tamper‑evident seals. Our logistics partners follow IATA + ICAO hazardous‑material protocols, and each batch is accompanied by a digital Certificate of Conformity.
We accept L/C at sight, T/T 30 days, and PayPal for samples. For recurring contracts, we can negotiate volume‑based discounts and extended credit lines.
Every cylinder comes with a 12‑month warranty covering material defects, plus a 24/7 technical hotline (WhatsApp, email, or phone). We also provide on‑site inspection services for large installations.
Limited‑Time Offer: Order before 31 May 2026 and receive FREE 2‑kg sample plus a money‑back guarantee if the cylinder does not meet your performance criteria.

John Smith, Purchasing Manager – USA – “The price cut was immediate, but the real win was the zero‑leak performance. Our safety audit scores jumped from 85 % to 98 %.”
Anna Müller, Technical Director – Germany – “Customization was seamless. The valve thread matched our robot’s quick‑connect system perfectly, shaving 10 minutes off each change‑over.”
Liu Wei, Operations Manager – China – “Fast 48 h delivery kept our production line running during a peak‑season surge. No downtime, no extra freight cost.”
