Product Description Product DescriptionThe steel pipe coupling is a short pipe or tube that with threads on both ends, used to connect pipelines. So It is a kind of pipe fittings that with threaded connection, the advantage is easy for pipeline maintenance or to replace the broken pipe.API Coupling refers to the steel couplings that used in connecting casing pipe and tubing. Also known by OCTG coupling, it is usually manufactured in seamless type, material grade same with the pipe body (API 5CT K55/J55, N80, L80, P110 etc), same PSL or providing higher grades than requested. Same heat treatment also applicable, except there is an special requirements.Product FeaturesNormally tubing coupling OD maximum is 4 1/2", as the tubing pipe is applied for the drilling activities (Inside the tubing is the sucker rod to drill/pump the oil), couplings type is more various and rigorous than casing, mostly used is thicken type upset coupling (Internal upset and external upset), for short is EUE coupling, it is the most favorable in tubing connections. Tubing with EU end (EUE) coupling connection also called UPTBG. Because of the end of the tubing is thickened (upset), the connecting stress is better than buttress coupling.Buttress coupling another type used for tubing connections, it has the same thickness of the pipe body, called NU end (NUE)tubing or TBG.The oil tubing coupling can solve the problem of fatigue fracture in the existing coupling due to stress concentration. Oil tubing end is connected to the inside wall of the coupling in a tapered thread. The coupling body end and oil tubing are connected with same thread pitch flat thread. The coupling is not easy to produce fatigue fracture, and has good connection effect. It can prevent the accident of oil well pipe string break effectively.Product ParametersTubing Pipe Outside Diameter(In)Tubing Pipe Outside Diameter(mm)Coupling Outside Diameter(mm)Minimum Length(mm)Diameter Of Recess(mm)Width of BearingFace Regular (mm)Max Bearing Face Diameter (mm)Mass(Kg)NUEEUENUEEUENUEEUENUEEUENUEEUENUEEUERegularSpecialClearanceRegular with special bevelSpecialClearanceRegularSpecialClearance1.948.2655.8863.50--95.2598.4249.8654.761.593.1852.0758.34--0.560.84--2 3/860.3273.0277.8073.91107.95123.8261.9367.464.763.9766.6871.8369.901.281.551.072 7/873.0288.9093.1787.88130.18133.3574.6380.164.765.5680.9885.8883.242.342.401.553 1/288.90107.95114.30106.17142.88146.0590.5096.854.766.3598.42104.78100.713.714.102.384101.60120.65127.00--146.05152.40103.20109.554.766.35111.12117.48--4.354.82--4 1/2114.30132.08141.30--155.58158.75115.90122.254.766.35123.19130.96--4.896.05-- Casing Pipe Outside Diameter(In)Casing Pipe Outside Diameter(mm)Coupling Outside Diameter(mm)Minimum Length(mm)Diameter Of Recess(mm)Width of BearingFace Regular (mm)Mass(Kg)Round(LTC/STC)BTCRoundBTCRound(LTC/STC)BTCRound(LTC/STC)BTCRoundBTCRegularSpecialClearanceSTCLTCSTCLTCRegularSpecialClearance4 1/2114.30133.35133.35123.82158.75177.80225.42116.68117.867.146.355.245.966.893.485127.00147.32147.32136.52165.10196.85231.78129.38130.567.147.146.437.868.384.005 1/2139.70160.02160.02149.22171.45203.20234.95142.08143.266.357.147.348.929.304.476 5/8168.28187.71187.71177.80184.15222.25244.48170.66171.836.356.359.1211.3411.015.657177.80200.03200.03187.32184.15228.60254.00180.18181.367.947.9410.8813.9213.986.287 5/8193.68215.90215.90206.38190.50234.95263.52197.64197.235.567.9412.1615.6315.829.298 5/8219.08244.48244.48231.78196.85254.00269.88223.04222.636.359.5215.6221.6720.8610.809 5/8244.48269.88269.88257.18196.85266.70269.88248.44248.036.359.5217.8525.4523.1612.0210 3/4273.05298.45298.45285.75203.20--269.88277.02276.616.359.5220.58--25.7413.3911 3/4298.45323.85323.85--203.20--269.88302.42302.016.359.5222.43--28.03--13 3/8339.72365.12365.12--203.20--269.88343.69343.285.569.5225.42--31.77--16406.40431.80431.80--228.60--269.88411.96410.315.569.5234.33--40.28--18 5/8473.08508.00508.00--228.60--269.88478.63476.995.569.5253.33--62.68--20508.00533.40533.40--228.60292.10269.88513.56511.915.569.5242.8156.9850.10-- Detailed Photos Company ProfileShijiazhuang Jimai Machinery Equipment Technology Co., Ltd is a large-scale professional manufacturer of drilling rigs and water well rigs in Hebei Province, China.
