We manufacture Metric Casing and Flush-Jointed Casing and Flush-Coupled Casing.
Sizes include BW, NW, HW, PW, HWT, 46mm, 56mm, 66mm, 76mm, 86mm, 98mm(101mm), 113mm(116mm), 128mm(131mm), 146mm(143mm), 4", 5", 6", 8", 10", 12", NX, HX, PX, 89 mm,108 mm, 127 mm, 110 mm.
Casings are often used when there is need to stabilize the drill hole and protect it from leaking, collapsing or water-bearing stratum. Casings are flush joint type and are available in W and WT threads. W casing utilizes the DCDMA W thread form. WT casing is made with DCDMA tubing and tapered thread form.
