Edatm supplies drill pipe, bits, downhole tools, blowout preventers, shakers, rig-floor machines and casing. Each item is quoted to the size and the standard on your order.
Profile
What we supply
Edatm supplies heavy equipment for oil rigs and for crude-oil refineries. The published contact address is 4 Dingwall Road, Croydon, CR0 2LX.
The drilling range covers the drill string, bits, downhole tools, well-control equipment, solids-control equipment, rig-floor tools, casing and the accessories that go with them. The refinery range covers heat exchangers, process valves and piping, and pumps and vessels when the duty is specified.
We sell and supply that equipment. We quote the tool, the standard and the quantity. We do not publish a performance figure that has no datasheet, and we do not describe mining or a contract to drill the well as our work.
Papers with the goods
Mill and material certificates are attached when the maker provides them.
A straight answer
We say when we can supply the item, and we say when we cannot.

Drill stringDrill pipeDrill pipe joins the surface equipment to the bottom-hole assembly, carries drilling fluid down to the bit, and transmits rotation and tension.
Drill bitsPDC drill bitsA PDC bit shears the formation with polycrystalline diamond cutters. It is selected for the rock, not from a single hardness number.
Well controlBlowout preventersA blowout preventer closes the well if formation pressure enters the borehole. Ram preventers are what the photographs show.
Refinery equipmentShell-and-tube heat exchangersA shell-and-tube exchanger transfers heat between two streams. On a crude unit it is how the feed is warmed before the furnace.
