C3H8 Gas Calibration Gas Factory High Grade Purity 99.999% 995 Propane for Etching CVD Epitaxy

Products Description

Propane (/ˈProʊpeɪn/) is a three-carbon alkane with the molecular formula C3H8. It is a gas at standard temperature and pressure, but compressible to a transportable liquid. A by-product of natural gas processing and petroleum refining, it is commonly used as a fuel in domestic and industrial applications and in low-emissions public transportation. Discovered in 1857 by the French chemist Marcellin Berthelot, it became commercially available in the US by 1911. Propane is one of a group of liquefied petroleum gases (LP gases). The others include butane, propylene, butadiene, butylene, isobutylene, and mixtures thereof. Propane has lower volumetric energy density, but higher gravimetric energy density and burns more cleanly than gasoline and coal Propane gas has become a popular choice for barbecues and portable stoves because its low −42 °C boiling point makes it Vaporise inside pressurised liquid containers (2 phases). Propane powers buses, forklifts, taxis, outboard boat motors, and ice resurfacing machines and is used

FAQ

1. What is the MOQ

A: From one cylinder

2. What is the delivery time

A: 7–10 days EXW (Ex Works) after we receive the deposit. Once we book the air freight, we will be able to provide the exact delivery timeline to the customer's country.

3. How do you check the gas quality

A: First, our team prepares the cylinders (cleaning, drying, vacuuming, pumping, and purging before gas filling to ensure the inside of the cylinder is clean and dry). Second, we test the treated cylinders again to confirm that the interior remains clean and dry. Third, we analyze the gas after filling the cylinders and provide a COA (Certificate of Analysis).

4. Can all cylinders be recycled

A: Generally, the service life of seamless steel cylinders is over 20 years. Disposable cylinders, however, are strictly for single use.

5. Can we send empty cylinders back to China for refilling

A: Yes. Once the gas is used up, you can return the empty cylinders to us for refilling. Please inform us prior to shipment so we can arrange customs clearance for the cylinders in China.

6. Available Cylinder and Valve Standards

A: Cylinder Standards: DOT-3AA, ISO9809, GB5099, TC-3AAM, EN1964, KGS

Valve Standards: DISS, CGA, DIN, BS, AFNOR, JIS

7. Can I ship LCL with my other general cargo

A: Our products are classified as Class 2.2 Dangerous Goods (DG) and must be shipped accordingly. Shipping them as general cargo is illegal, so we must book DG transport with the carrier. If you have general cargo, it can be combined with this shipment, provided the entire load is shipped under DG standards
