" H-9 International Association of Drilling Contractors Chapter H: Rotary Hose & Swivel H2. Rotary Hose Care And Maintenance I. Recommended Dimensions A. Hose Length In order to avoid kinking of hose, the length of hose and height of standpipe should be such that while raising or lowering, as in making mousehole connections, the hose will have a normal bending radius at the swivel when the hose is in its lowest drilling position and at the standpipe when the hose is in its highest drilling position. The recom- mended length of hose is given by the following equation, see Figure H2-1. Figure H2-1 Layout for Rotary Hose Lh = Lt/2 + nR + S Wherein: Lh = length of hose, in feet. Lt = length of hose travel, in feet. R = minimum radius of bending of hose, in feet, = 3 ft for 2 inch hose = 4 ft for 2-1/2 and 3 inch hose = 4-1/2 ft for 3-1/2 inch hose S = allowance for contraction in Lh due to maximum recommended working pressure, in feet, which is 1 ft for all sizes of hose. B. Standpipe Height The recommended standpipe height is given by the following equation, see Figure H2-1. H-10 International Association of Drilling Contractors IADC Drilling Manual - Eleventh Edition Hs = Lt/2 + Z Wherein: Hs = vertical height of standpipe, in feet. Lt = length of hose travel, in feet. Z = height, in feet, from the top of the derrick floor to the end of hose at the swivel when the swivel is in its lowest drilling position. When the actual length of hose is greater than the length calculated as above, the standpipe height should be increased by one-half the difference between the actual length and the calculated length. C. Hose Connections The threaded connection on the rotary hose is capable of handling the rated pressure and should not be welded to its connector as this will damage the hose. The connections between the rotary hose, standpipe and swivel should be consistent with the design working pressure of the system. The connections attaching the hose to the swivel and to the standpipe should be as tangential as possible. The use of a standard connection on the swivel gooseneck will insure this relationship at the top of the hose. The gooseneck on the standpipe should be selected to provide for connecting the rotary hose at an angle 15 degrees from vertical (Figure H2-1). II. Care And Maintenance A. Handling To minimize the danger of kinking, the hose should be removed from its crate by hand, laid out in a straight line, then liked by means of a catline attached near one end of the hose. If a catline is used to remove the hose from its crate, the crate should be rotated as the hose is removed. The use of a carrier to protect the hose in moving to a new location is a recommended practice. It is considered bad practice to handle hose with a winch, to hang the hose from a truck gin pole, or to place heavy pieces of equipment on the hose. B. Twisting Hose should not be intentionally back twisted. Twisting is sometimes employed to force the swivel bail out of the way. This places injurious stresses on the structural members of the hose body, because one spiral of reinforcing wires is opened and the other is tightened, thus reducing the resistance of the hose to bursting and kinking. In order to prevent twisting, it is suggested that a straight swivel be installed on one end of the hose. Each length of hose has a longitudinal lay line of a different color than the hose cover. This should be used as a guide in making certain the hose is installed in a straight position. C. Clearance The hose installations should provide adequate clearance between the hose and the derrick or mast. D. Safety Chains The safety chains should be as short as possible without restricting the movement of the hose when the swivel is at its highest point and lowest point of operations. The safety chain at the standpipe end of the hose should be attached to a derrick upright rather than to a transverse girt, the chain can then move upward should the traveling block be raised too high. The safety chain at the swivel end of the hose is attached to the lug on the swivel body or housing. H-11 International Association of Drilling Contractors Chapter H: Rotary Hose & Swivel E. Vibration and Pulsation Continual flexing is injurious to drilling hose and reduces its service life. Pulsation dampeners should be installed in the mud pump discharge line and suction stabilizers installed in the mud pump inlet line to reduce the magnitude of the pressure surges. Pre-charge pressures for the dampeners and stabilizers will be stated by the manufacturers. F. Working Temperature Working temperature should not exceed 180 H-12 International Association of Drilling Contractors IADC Drilling Manual - Eleventh Edition H3. Swivels Specifications I.

H-14 International Association of Drilling Contractors IADC Drilling Manual - Eleventh Edition H4. Inspection I. Inspection All hoisting tools on the rotary drilling rig must have daily inspections followed by monthly and quarterly (more frequent if severe operating conditions or loading is imposed) shutdown inspections. A. General Inspections 1) Field inspection of hoisting equipment in an operating condition should be made by crew or supervisor on a daily basis. 2) The monthly inspection is The same as The daily inspection except the equipment is shutdown, all oil and grease removed from surfaces to be inspected (use detergent if necessary) and paint is removed from high stress areas. The equipment should be kept clean by a daily hosing and/or brushing in order that the daily in-operation visual inspection can be effective. Persons inspecting hoisting equipment on a daily basis should look for cracks, loose fitting connections or fasteners, elongation of parts and any signs of excessive wear or overloading. Any equip- ment found to show cracks, excessive wear, circ., should be removed from service immediately. 3) The quarterly inspection is the same as the monthly inspection this inspection is recorded on a log sheet and retained for future reference. B. Disassembly Inspection 1) Equipment should be taken to a suitably equipped facility and all parts checked for excessive wear, cracks, flaws, etc. Visual and non-destructive (NDT) techniques are used. Where, in the opinion of the user, excessive wear is noted, it is recommended that the matter be discussed with the manufacturer. 2) The equipment should be disassembled as much as necessary to permit NDT inspection of all load bearing parts. 3) All parts must be cleaned, by a suitable method, of all dirt, paint, grease, oil, scale, etc., before inspection. 4) The inspection is to be made by only technically competent personnel. 5) Minor cracks or defects, which may be removed without reducing safety or the operational rating of the equipment, can be so removed by grinding or filing (preferably in consultation with manufacturer). 6) Following removal of the defect, the part should again be inspected by an appropriate NDT method to insure that the defect has been completely removed. 7) For other than minor defects or cracks, refer to REPAIRS which follows. C. Repairs CAUTION: Repairs and modification, including welding, without approval of the manufacturer can substantially reduce the rating of the tool. 1) If repairs are not performed by the manufacturer, such repairs should be made in accordance with methods or procedures approved by the manufacturer. 2) If the tool or part is defective beyond repair, it should be destroyed immediately upon so determining. 3) Field welding should not be done on any hoisting tools, because without full knowledge of the design criteria, the materials used and the proper control when welding (stress relieving, normalizing, tempering, etc.), it is possible to reduce the strength of the tool sufficiently to make its continued use dangerous. H-15 International Association of Drilling Contractors Chapter H: Rotary Hose & Swivel In addition to the daily and quarterly GENERAL INSPECTIONS, the rotary tool joint connections in the drill string, above the rotary table, must be independently inspected for integrity or indications of possible failure. D. Frequency of Inspection It is the responsibility of the owner/operator to dictate the frequency of these inspections. In this matter, it is suggested that reference be made to records of previous inspections, if deterioration is progressing it may be necessary to make inspections at a rate of more than normal frequency. Consideration should be given to drilling conditions, loading of the drill string, tensioning when hoisting underreamers, pulling the kelly with junk in the hole, bit stuck on bottom, etc. As a minimum these inspections should be made prior to drilling to any of the deeper formations or after drilling approximately 50,000 feet in shallow areas. These connections should also be inspected every time the drill pipe is inspected. E. Inspection Methods Normally the inspections are made by specialty companies having the proper equipment, gauges and trained personnel. Any of the present methods; ultrasonic frequencies, magnetic particle or other electromagnetic tech- niques, if they are approved by the owner/operator or the contractor, should be satisfactory. In the absence of the specialty companies, the swivel body (stem) tool joint box, the pin-and-pin swivel sub and other rotary tool joint connections above the rotary may be inspected by using a liquid penetrant. The cleaner, the penetrant and the developer can be obtained for spray application or for an immersion method of testing. The American Society for Testing and Materials (ASTM) outlines in their publication E165-75, an immersion method for this testing. Some training may be required for the proper interpretation of liquid penetrant inspections. F. Inspection Procedures When inspections are made by specialty companies they will outline the inspection procedures. When inspections are made with liquid penetrant, follow the instructions prescribed by the manufacturer of the penetrant or ASTM specification. The cleaning of the area to be inspected will be an important factor in obtaining satisfactory results from liquid penetrant testing. It is not easy to clean the bore of the swivel body (stem) especially on smaller swivels, but it has to be done. A slow speed electric drill with a wire buffer wheel on a shaft extension can aid in this internal clean- ing. Mechanic's mirrors or a bore-scope may be needed to check the cleaning and inspect the testing area. Always use approved thread gauges to check each box and pin before making-up any of these rotary tool joints. Remember, all standard tool joints above the rotary have left hand threads. Obtain a written report of all test results and make the report a part of your permanent records. G. Possible Causes of Tool Joint Failures * Failure to inspect and gauge the tool joints. * Infrequent inspections and gauging. * Improper interpretation of test results. * Worn thread gauges. * Damaged box or pin prior to make-up. * Box and pin not squarely shouldered.
