Heavy Weight Drill Pipe (HWDP)

Heavy Weight Drill Pipe (HWDP) Our Heavy Weight Drill Pipe (HWDP) offers a gradual transition from heavy, rigid drill collars to the more flexible drill pipe which helps to reduce  the number of fatigue failures seen directly above the Bottom Hole Assembly (BHA). We offer heavy weight in 3.1/2″, 4″, 5″ and 5.1/2″ consisting of hard banded tool joints and raised wear pads on central upsets to optimize wear  resistance. We offer two types of HWDP configurations; Standard HWDP and Spiral HWDP. Standard HWDP Prevents stress concentration and allows directional drilling with controlled torque and reduces differential pressure sticking. Spiral HWDP Designed to handle maximum stresses induced at harsh drilling environments in vertical and directional wells. Shares many of the same features from the Standard HWDP. Better reduction in differential sticking Increased weight and stiffness Minimizes wear Improves cutting circulation for better hole cleaning Our preferred applications of hard banding for drill pipe tool joints and BHA components (HWDP, Drill Collars) are ARNCO 350XT or Duraband  NC, both NS-1 certified; which are not only designed to protect the drill pipe from wearing but also to protect the casing. We use a robotic welding system for  hardbanding drill pipe. HWDP – 3.500 – NC38 HWDP – 4.000 – MT39 HWDP – 4.000 – XT39 HWDP – 5.000 – NC50 HWDP – 5.500 – HT55 HWDP – 5.500 OD x 3.250 ID – DPMDS55 HWDP – 5.500 OD x 4.000 ID – DPMDS55

How is the theoretical weight of spiral steel pipe calculated?

  The theoretical weight of steels is obtained by calculating nominal dimensions and density (which is called specific weight in the past). This is directly related with the steel length, the cross section area, and the allowable size deviation. Because of the allowable deviation in the process of manufacturing, the calculated theoretical weight […]

Corrosion Resistance of API 5L Pipeline Steel with Coating Protection

ABSTRACT The corrosion resistances of enamel-coated steel pipe in  3.5 wt% NaCl solution was evaluated and compared with those of epoxy-coated pipe using open-circuit potential, linear po- larization resistance, and electrochemical impedance spectros- copy tests. T-001c enamel slurry and GP2118 enamel powder were sprayed to steel pipe in wet and […]
