Boyd Bros Concrete is an authorized Praxair depot. We carry an assortment of Oxygen, Acetylene, Argon, Auto-weld and Mig Mix Gold gases, in a number of canister sizes. For registered Praxair customers we have a canister swap out program, however, smaller canisters sizes marked with ‘C.O.P.’ are considered Customer Owned Property and do not require Praxair registration.
Canisters & Sizing:
Typically used for cutting, welding and melting metals. The gas is capable of generating temperatures of 2800 C and 3000 C. This is required for oxy-hydrogen and oxy-acetylene blow torches.
Acetylene is used for welding and cutting. The welding process that uses acetylene is known as oxy-fuel cutting or gas cutting. This method is used to cut or weld materials that require temperatures as high as 3,500 °C (6,330 °F). Among all other gases, acetylene is capable of producing the hottest flame. For this reason, acetylene serves as an important medium for heat treating metals and other materials
Argon is valued for its total inertness, in particular at high temperatures. Argon is used in critical industrial processes such as the manufacturing of high quality stainless steels and as an inert filler gas for light bulbs. The gas is approximately 1.4 times as heavy as air, and is slightly soluble in water. Argon’s freezing point of -308.8°F is only a few degrees lower than its boiling point of -302.6°F
