Refurbished Products - Oil Field

Complete servicing and reconditioning of all types of BOPs i.e. Ram BOP, Annular BOP, I-BOP' The scope includes repair of API ring grooves with SS inlay, re-building of piston, body, cover, stress relieving with chart recorder and complete NDT tests are carried out during the reconditioning process. Assembly of BOPs with new seals of existing design and profile from Indigenous / OEM Make. Testing and approval by OEM / third party inspection like ABS, BV, GL etc.

United Van Der Horst has successfully combined specialized welding technology and hard chrome plating technology for the complete reconditioning of damaged or worn out components of diesel engines such as a) Crankshafts b) Liners c) Cylinder Heads d) Exhaust Valves e) Connecting Rods f) Pistons g) Engine Blocks (Crank cases). Hard chrome plating of ring grooves of piston crown for better sealing and wear resistance, porous chrome of engine liners for improved lubrication, satellite inlay on seating face of valve seat and valve spindle for wear resistance, straightening of crankshaft and maintaining the bearing diameters to its original dimensions by hard chrome plating. Since the past 2 decades United Van Der Horst has served the Oil Field Industries with compete satisfaction. Our API certification has been a source of inspiration for continued improvement and up gradation. The entire procedure are approved by classification societies like IRS, DNV, BV, Lloyds.

Repair include dismantling of gear box from RIG, replacement of damaged roller bearings, Modification of Oil seal, Repair of damaged base plate, Installation of gear box back in to Rig.

The procedure includes testing of material, weld build up of broken teeth with compatible electrodes, profile matching of teeth. The shaft diameters and the bearing and the sealing areas are re-built back to standard diameter by the hard chrome plating and grinding process. Modifiedor OEM Rotary Shaft Seals with latest technology and with different sealing profiles are available.

Re-conditioning of crank shaft up to 10 meters long with a swing over a diameter of 1.2 meters. Repairing of crankpins and main Journals by juxtaposing the grinding process. Services for crank-shaft also includes straightening of crankshaft by peening method, full dimensional inspection in addition with magnaflux crack detection. The entire procedure are approved by classification societies like IRS, DNV, BV, Lloyds. Inspection of final product is witnessed and certified by the respective classification society.
