Product Description Product DescriptionA drill collar is an essential tool used in oil and gas rigs for drilling operations. It has many functions, including providing weight on the drilling bit for efficient drilling and stability during operation.Designed to place weight on the drill bit and pump drilling fluids, our drill collars are integral heavy-wall joints manufactured from a solid bar of modified alloy steel. The solid bars are quenched and tempered to obtain the required mechanical properties and then trepanned, drifted, and threaded. Our drill collars are furnished as slick or spiraled; spiraled drill collars have grooves machined in the outside surface that promote the even flow of drilling fluid around the drill collar diameter, equalizing pressure and reducing the occurrence of differential sticking.Functions:(1) Apply drilling pressure to the drill bit;(2) Ensure the necessary strength under compression conditions;(3) Reduce the vibration, swing and jumping of the drill bit to ensure smooth operation of the drill bit;(4) Control well inclination.Drill collars are generally classified into three types: spiral drill collars, non-magnetic drill collars, and integral drill collars.Product ParametersOutside diameter(in)Inside diameterModeWeightWeightStandard(in)Customization(in)StandardCustomizationStandard inside diametercustomization diameter30 in31 in30 in31 in3 1/81 1/41NC232-3/8 REG2963063153263 1/41 1/41NC23NC23 2-3/8 REG3253363453573 1/21 1/21 1/4NC28(2-3/8 IF)NC28(2-3/8 IF)3583703843974 1/821 3/4NC31(2-7/8 IF)NC31(2-7/8 IF)4694855035204 1/421 3/4NC31(2-7/8 IF)NC31(2-7/8 IF)5095265415594 1/221 3/4NC31(2-7/8 IF)NC31(2-7/8 IF)5856056176384 3/42 1/42NC35NC38(3-1/2IF)62965066869052 1/42NC38(3-1/2IF)NC38(3-1/2IF)7167407557805 1/42 1/42NC38(3-1/2IF)NC38(3-1/2IF)8108388508785 1/22 1/42NC38(3-1/2IF)NC38(3-1/2IF)9059359449755 3/42 1/42 13/16NC40(4FH)4 1/2FH1009104390593562 1/42 13/16NC44NC40 (4-1/2FH)11141151101110456 1/42 1/42 13/16NC46(4IF)NC46(4IF)12241265112311606 1/22 1/42 13/16NC46(4IF)NC50(4-1/2IF)13401385123712786 3/42 1/42 13/16NC46(4IF)NC50(4-1/2IF)146615101355140072 13/162 1/4NC50(4-1/2IF)NC50(4-1/2IF)14811530157716307 1/42 13/163NC50(4-1/2IF)5-1/2FH16071661156816207 1/22 13/162 3/4NC50(4-1/2IF)5-1/2 REG17411799175218107 3/72 13/163NC56(6-5/8REG)NC56(6-5/8REG)187719401848191082 13/163NC56(6-5/8REG)NC56(6-5/8REG)20182085197920458 1/42 13/1636-5/8REG6-5/8REG21682240212721988 1/22 13/1636-5/8REG6-5/8REG23152392227423508 3/42 13/1636-5/8REG6-5/8REG2473255524342515932 13/16NC61 (7-5/8REG)NC61 (7-5/8REG)25892675262727159 1/432 13/16NC61 (7-5/8REG)NC61 (7-5/8REG)27582850279728909 1/232 13/167-5/8REG7-5/8REG29233020296130609 3/432 13/16NC70 (7-5/8REG)NC70 (7-5/8REG)30983200313632401032 13/16NC70 (7-5/8REG)NC70 (7-5/8REG)3276338533163427 Company ProfileShandong Hande Automation Control Equipment Co., Ltd. was established in 2007.
