WARNING: Only original BVMparts may be used. Slip sets are produced fromcast alloy heat treated steel and must not be welded in the field. Improper weldingcan cause cracks and brittleness in heat-affected areas which can result in dramaticweakening of the part and possible failure. Repairs involvingwelding and/ormachining should be performed only by a BVMauthorized repaír facility. Using anSlip set that has been improperly welded or repaired is dangerous.

WARNING: Slip setswhich have experienced wear beyond established wear criteriaset by OEM, or are found to have cracks must be replaced.

CAUTION: Practice safety in the operation and maintenance and use only approvedsafety methods, materials and too/s. Keep hands awayfrom any pinch point orundesignated areas; use only the provided hand/es for operating the slip.

Do not set slips on larger size pipe than they were designed to hold. When 5inch slips for examp1e,are used on 5 inch pipe, the inserts have the proper contour.If the slip is used on 1argerpipe or on too1joints, the stress is placed on the outsidecomers of each segment. This causes the slip bodies to spread and crack. Afier theslip has been used on 1argerpipe and then placed on the pipe size for which it was

The well drilling industry has had many accidents caused by slips being set onmoving pipe. The drill pipe must be stopped completely before the slips are set onthe pipe. The driller should look at the weight indicator to see that he is holding thefull load. If the bit should hit a ledge which supports part of the weight of thestring, when the elevator is removed the pipe could be jarred free and the fullshock load dumped on the slips. When the shock load hits the slips, the drill stringacts like a rubber bandoA 15,000 foot (4572 m) string of 4-1/2 inch drill pipe canstretch approximate1y 38 feet (11 m). The string will start to bounce and couldcause the slips to be thrown out of the rotary table; then the pipe will be dropped inthe hole. If the pipe does not go in the hole and the slips do hold, another prob1emcould occur; the drill pipe is cou1d be permanent1y deformed and cracked justbelow the slips, resulting in wash-outs.

SDS Slips are designed for shallow hole drilling SDML Slips are the perfect choicefor all medium depth drilling. With the proper drill string design they can handledepths beyond 20,000 feet. BVM SDXL Slips are designed for deep drilling.

BVM rotary slips are designed to provide long and troublefree service under themost severe conditions. Inserts are he1d securely in dovetail slots and are easilychanged by removing the nuts, bolts, and retainer at the top of the slots.

This series of Slips are for use in API standard insert bow1s.These slips featureimproved contact on drill pipe through a superior wrap around configuration andunique insert design that helps to prevent bottlenecking and gouging damage. Thebuttress design of the body segments provides great strength while minimizingweight for ease of handling.

NOTE: The owner and user together with the manufacturer should jointly developand update inspection, maintenance, repair and remanufacture proceduresconsistent with equipment application, loading, work environment, usage and otheroperational conditions. These factors may change from time to time as a result ofnew technology,equipment history, product improvements, new maintenancetechniques and changes in service conditions.

Slip segment hinges should be inspected regulary to see that the hinge pin islocked into position with the cotter pin and not wom or cracked. Slips that sag or

Placing a straight edge against the backs and inside face of the slips willindicate if they are bent or wom. A good slip back is straight, smooth, and wellgreased.

Periodic inspections should be performed on drill pipe and drill collar slips as apreventive measure. Areas of particular concem are slip segment hinges and thehinge pins.

Slip Inspection

The slips and bowl ID should be dressed as well as cleaned to prevent sticking ofthe slips. Abrasive materials in the drilling mud can cause horizontal lines of wearin the mating surfaces of the slips and bowls. Dressing these surfaces, using an upand down motion with emery cloth will result in the grain of the two parts runningwith each other to significantly reduce friction.

Dressing Slips and Insert Bowls

A word of caution: There are times when setting the slips that the driller doesnot pick up enough to get the rotary slips around the pipe. In this case the top of therotary slips is on the tool joint. When the drill pipe is lowered, the slip' s body isbridged between the master bushing and the pipe. This causes the back of the slipsto bend. The normal reaction is to raise the string and let the slip segment settlearound the pipe. The slip segments have been bent and when placed in the masterbushing around the pipe, they will bend back to their original form, however,cracks may have developed in the slip bodies. As a result of this, the toe of the slipcould break and fall into the holeo If the driller runs into a slip, inspect it or use anew set until the damaged slip can be inspected properly.

Clean the inside taper of the drilling bowls to remove any abrasive material.Lubricate the inside taper of the drilling bowls frequently with grease to preventslips from sticking in the bowls. Warning: Never use pipe dope to grease the backof the slips.

Critical WearAreas

Check inserts and insert slots for damage or wear. When the insert slots arebadly worn, danger of losing an insert down the hole exists. Replace the slipsbefore a costIy failure occurs. Slips should be replaced when there is over 1/8 inchto 3/16 inch (3.2 to 4.8 mm) c1earencebetween the back of the inserts and theinsert slot.

flop over when standing alone on the rig floor, are extremely worn in the hingearea. Pull thee hinge pins and check for straightness. A bent hinge pin will indicateoversize hinge pin holes. Oversize hinge pin holes are cause for replacment of theslips. If not replaced, wear will increase at an accelerated rate until the slips do notset correctly in the master bushing. This could damage drill pipe.
