Drilling Rig Pipes for Water Well and Mining& Oilfield

  Our AdvantagesThis large channel allows fluid to flow freely as the packer is run, recovered, and circulated, greatly reducing cartridge friction and avoiding ball-tooth collisions. The packer can be used in high pressure Wells where a hydraulic anchor can effectively prevent the packer from going up. At the same time, the pressure also acts on the balance piston, which moves down against the center pipe and the seal sleeve. This principle eliminates excess set load and keeps the packer's bypass balance channel closed. Characteristics 1, can be safely set in all levels of casing; 2, reliable sealing system, in the operation can withstand the pressure difference up and down; 3, ground control bypass channel and pressure balance valve; 4, balance piston structure to strengthen the stability of the tool under pressure; 5. Automatic J-type device can easily achieve setting and unsealing, and can be set several times after entering the well; 6. Lifting the tubing will first open the bypass valve to balance the pressure, to ensure the safety of unsealing operation; 7, can withstand high pressure, 7 "and below specifications can withstand up to 70MPa (10000psi) pressure difference. Iv. Specifications and models   Product DescriptionIn oilfield drilling engineering, oil drill pipe is the main component connecting ground rotation system, lifting system and circulation system with drill collar and drill bit. Through these components, the rotary wheel drives the drill bit to rotate, the big hook drives the drill bit to lift, and the mud is sent to the bottom of the hole to form circulation, so as to realize the drill bit breaking rock layer and continuous drilling.Great Petro anti-sulfur drill pipe is a special drill pipe independently developed by Great Petro to meet the needs of oil and gas exploration and drilling in areas with sulfur and high sulfur content, which has the stress corrosion resistance of hydrogen sulfide.Product advantageOn the basis of the first generation of DT-S 95 and DT-S 105 antisulfur drill pipe suitable for use in moderate H2S corrosion environment, by optimizing the chemical composition of materials and heat treatment process, The second generation of DT-SS 75, DT-SS 95 and DT-SS 105 anti-sulfur drill pipe suitable for use in severe H2S corrosion environment has been developed. The performance indexes of the SS series of anti-sulfur drill pipe meet the requirements of IRP1.8, NACE MR0175 and ISO15156 standards.Product specificationProduct size: Covers all API standards from 2-3/8 "to 6-5/8"Steel grade: DT-S 75, DT-S 95, DT-S 95, DT-S 105Product Parameters    DT-S 75,DT-S 95DT-S 105DT-SS 75DT-SS  95DT-SS 105drill pipeyield strength(MPa)517-654654-758723-827517-654654-758723-827Tensile Strength(MPa)654-792723-896792-965654-792723-896792-965ballistic work(J)3/4size,-20ºC≥70≥80≥80≥70≥80≥80Maximum single value of hardness(HRC)242729242729SSC Test70%SMYS;Method A;720h85%SMYS;Method A;720hconnectionyield strength(MPa)758-861758-861758-861758-861758-861758-861Tensile Strength(MPa)861-999861-999861-999861-999861-999861-999ballistic work(J)3/4size,-20ºC≥89≥89≥89≥89≥89≥89Maximum single value of hardness(HRC)323232323232SSC Test---65%SMYS;Method A;720hSizeODWEIGHTTHICKNESSRSC typeSteel gradeThickening typeSize 1Size 2inlb/ftinchmmlb/ftkg/minmm///2 3/86.652.37560.326.269.330.2807.11NC26E, X, GEU2 7/810.402.87573.029.7214.470.3629.19NC31E, X, G, SEU3 1/213.303.50088.9012.3118.340.3689.35NC38E, X, G, SEU15.503.50088.9014.6321.790.44911.40NC38, NC40E, X, G, SEU4   14.004.000101.6012.9319.270.3308.38NC40, NC46E, X, G, SEU, IU4 1/216.604.500114.3014.9822.320.3378.56NC46, NC50E, X, G, SEU, IEU20.004.500114.3018.6927.840.43010.92NC46, NC50E, X, G, SEU, IEU5   19.505.000127.0017.9326.700.3629.19NC50, 5 1/2 FHE, X, G, SIEU25.605.000127.0024.0335.800.50012.70NC50, 5 1/2 FHE, X, G, SIEU5 1/221.905.500139.7019.8129.520.3619.175 1/2 FHE, X, G, SIEU24.705.500139.7022.5433.570.41510.545 1/2 FHE, X, G, SIEU6 5/825.206.625168.2822.1933.040.3308.386 5/8 FHE, X, G, SIEU27.706.625168.2824.2236.060.3629.196 5/8 FHE, X, G, SIEU Packaging & ShippingThe packer is designed for a range of casing sizes from 4 1/2 "to 16" and features a large diameter, pressure-balancing valve that can be controlled at surface. /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
