Q: What's your product price?
A: Pricing for each gas is influenced by market supply and demand, quantity, and purity, making it difficult to set a fixed price. If you are interested in any specific gas, please provide your detailed requirements, and I would be happy to offer you a tailored quote.
Q: What is the minimum order quantity?
A: Minimum order quantities vary across different products. Please share your specific requirements with us, and we will provide the relevant details.
Q: What is the delivery time?
A: If the cylinder is in stock and only requires gas filling, delivery is approximately 7-10 days ex-works after receiving the deposit. Custom cylinder orders require about 15-35 days ex-works post-deposit, depending on the quantity.
Q: How do you ensure gas quality?
A: Our cylinders undergo a thorough treatment process, including cleaning, drying, vacuum pumping, and replacement before gas filling to ensure they are clear and dry. Each treated cylinder is tested for internal purity. After filling, all gases are tested once more. If the gas fails to meet standards, it is reprocessed. Finally, we provide a qualified gas test report.
Q: Are all cylinders recyclable?
A: Typically, seamless steel cylinders are recyclable. However, disposable cylinders are intended for single use only.
Q: Can we send back cylinders to China for refilling?
A: Yes, you can send back our cylinders for refilling. Inform us before exporting, and we will manage all necessary import customs clearance formalities.
