The drill rods and casing provided by Dalemei ensure the steel grade and mechanical performance. The pipes are subjected to non-destructive testing using eddy current and ultrasonic testing to ensure that there is no damage inside the pipes and the quality is good.

Impregnated Diamond core bits Description: The impregnated diamond drill bits are the most commonly useful bits in the mineral exploration industry, as they have the widest range of application. The high grades of synthetic diamond are distributed in the bit's matrix. Casing Shoe: The casing shoe bit is mainly used in handling casing tube in the shallow earth surfaces, and we have casing shoes bit in different hardness to better fit various casing tube bits. The casing shoe diamond bit is mainly made up of diamond single crystal steel body, tungsten carbide and polycrystalline diamond. Main functions of casing shoe: 1): Protect casing ends from distortion. 2): Help casing pass through stratum to bed rock. 3): Carry mud to earth surface. 4): Help down-pass of casing when drill rod is in hole. size available: Q series(Wireline Series): AQ, BQ, NQ, HQ, PQ, SQ,BQ3, NQ3, HQ3, PQ3 W Series: RW, EW, AW, BW, NW, HW, PW, SW, UW, ZW, HWT, PWT, BWS, NWS Metric Series: 46, 56, 66, 76, 86, 101, 116, 131, 146 X Series: RX, EX, AX, BX, NX, HX, PX, SX, UX, ZX TT series: NQTT, HQTT,PQTT

As a manufacturer and a supplier we produce cementing tools since 1997, and now we have almost 400 workers, the products cover cementing head/plug, stage collar, float equipment, centralizer and so on. Please contact me if you have need, and my email is Maggie@pyzs-group.com, WhatsApp is +8613939319501. Our website is www.pyzs-group.com The casing head is a kind of part of connecting casings and wellheads. It is used to support the weight of technical casing and intermediate casing and seal the annular space between the casings, which provides a transition joint for the installation of the tubing head, Christmas tree and other wellheads. The two-side-outlet design allows the casing head to supply cement, monitor and control well's sinking, and inject balance liquids etc. Casing head design features a 45 degree landing shoulder. This design avoids damage to sealing areas by drilling tools and prevents test plug and blow protector wedging problems when pressure is applied. This design also allows for accurate vertical positioning of annular seals, control line porting and test ports.

In most operations, a bottom plug is launched before the spacer of cement slurry. The top plug is released form the cement head after the spacer fluid. Most cement heads can hold both the top and bottom plugs. A manifold incorporated into the cement head assembly allows connection of a fluid circulation line.
