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.
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.
Pinion is a part of Rack -Pinion system of Mechanical Jack -Up rig, repair includes machining out the damaged bearing diameter on both NDE (non drive end) & DE (drive end) Weld build up with compatible weld electrode, Stress relieving, Finish machining & grinding of bearing diameters to maintain the tolerance as per requirement. All inspections are carried out under ABS supervision.
Hubs are part of Rack -Pinion system of Mechanical Jack -Up rig, repair includes machining out the damaged bearing diameter on both NDE (non drive end ) & DE (drive end) Weld build up with ABS -Huston (USA) approved Aluminum -Bronze Cladding on bearing diameters. Finish machining & Honing of bearing diameters to maintain the tolerance as per requirement. All inspections are carried out under ABS super vision.
Rotor Shaft is a life line of oil drilling rigs which provides rotating power to the drilling Head /tool. Repair scope includes hard chrome plating of helical flutes which provides wear resistance surface. Surface hardness of chrome plated surface shall be minimum 65 Hrc & Surface finish value less than Ra 0.3 microns. Deep dents marks / Pitting marks shall be locally repaired before hard chrome plating.
United Van Der Horst has a well equipped, high precision machine shop with horizontal boring machines, centre lathe machines, vertical turret lathes, crank-shaft grinding machine, universal milling machine, radial drilling machine, etc for machining jobs up to 1.2 meter diameters and in excess of 10 meter length.
At United Van Der Horst, with the innovation of Van Der Horst-Holland for advanced chrome plating technologies such as "Porous Krome" and "hard chrome" plating for different diesel engine components & various other parts of hydraulics. United Van Der Horst can easily boast about its excellence safety. Components are chrome plated with hardness up to 60-65 HRC and are super finish to achieve required surface finish value. Porous chrome plating processes provides better lubrication and lower wear rate resulting in longer service life of Diesel Engine Components, Cylinder Components. Plating process followed by United Van Der Horst has been approved by American Bureau Society (ABS) and tested at NABL approved laboratory for Salt Bath Test, Chrome peel off test, Hardness Test.
Honing can be done to a very close tolerance and with high surface finish value. With their self-aligning mechanism we are capable of maintaining the concentricity and circularity within 5 to 10 microns. Our valued customer bear testimony to our competence of our two Gehring make German vertical honing machines. Jobs with bore diameter up to 1200mm and length in excess of 8 meters, can easily be honed on our vertical honing machines.
The three nos. Friedrich Schmaltz-German make cylindrical grinding machines equipped with CNC controlled, cylindrical cum crank-shaft grinding facility. At United Van Der Horst we ensure that jobs are immediately undertaken to precision grinding and are super-finished with accuracy of 0.001mm that is 01 micron. Jobs with diameters up to 1250 mm ad lengths in excess of 11 meters are easily accommodated.
Our welding capabilities cover the entire spectrum of welding - SMAW, SAW, GTAW, MMAW, TIG, MIG and other such as for pressure containing parts, overlays. With approval for specialized welding like Aluminium Bronze Cladding from ABS-Houston wee can provide wear and tear resistance surface for load, guide bearing components. Our capacity to handle welding of components in excess of 10 tons makes handling of welding components of various type very convenient.
The Electrical Stress relieving furnace is computer controlled which ensures the right cooling and heating rate. It is equipped with two heavy duty blower which ensures uniform temperature all around the furnace. With its mechanized door and trolley operations one can get the excess of job very easily. This can take jobs up to size 8 meter cube. The maximum temperature achievable is 900° C
