DRILCO Hevi-Wate transition drillpipe, manufactured to specifications more stringent than API specifications, is the industry standard for an intermediate-weight drillstem member, and is available in standard, spiral, and nonmagnetic designs. It has corresponding drillpipe dimensions and can be picked up with the drillpipe elevators for fast, efficient handling on the rig floor.
Hevi-Wate drillpipe uses a unique center upset or wear pad that keeps the tube away from the hole wall, increasing tube life while reducing hole drag and differential sticking problems. The API bore back box feature is standard for the box connection on 4-in Hevi-Wate drillpipe and larger, helping to extend the service life of the connection. In addition, cold-rolling the thread roots on the connections increases their ability to resist fatigue cracking.
Hardbanding is an optional feature that can be placed on the tool joints and center wear pad to increase abrasion resistance. The API stress-relief groove feature on the pin connection, for sizes 4 in and larger, is another available option.
Using a string stabilizer above the drillpipe increases the amount of swarf to surface in deep water.
