The advantage of friction welding is that, different steel qualities can be chosen for the mid-body section and the tool joints. High quality alloy steel is used for the tool joints, Zero maintenance, and long lasting life of the rods. When required, an additional surface hardening can be applied to the tool joints for increased wear resistance. The rods have spanner flats on the pin and box ends. Plastic/Metal thread protectors are available for all API connection types. The rods are suitable for both DTH hammer and rotary drilling on (Top Drive Machine) The drill pipes can also the supported with fully induction hardened to increase the life.

API P530 Non-magnetic Drill Collar Materials: The non-magnetic products of Dongying Lake is made from high-class low carbon stainless steel, and completely meets the requirement of API Spec 7-1 and SY/T5144 Standard. It has good low magnetic permeability, high mechanical property and perfect enduring intergranular corrosion cracking performance. It is mainly used for the inspection in the process of petroleum drilling, and the structure is the same with the ordinary drill collar. Trepanning and Heat Treatment: Drill collars are trepanned and drifted to API Spec 7-1. Full-length heat-treatment processes ensure that mechanical properties meet or exceed API Spec 7-1 requirements. A hardness range of 285-341, Brinell hardness and Charpy "V" notch minimum impact strength of 40 ft-lb at 70 F are guaranteed one inch below the surface. Traceability: Drill collar material and process traceability are maintained from receipt of the mill's certified raw material to completion of manufacturing. Serial numbers are die stamped on bar bodies. Rigid Inspection Procedures: We inspect all our drill collars to ensure compliance with API SPEC 7-1 standards. These inspections include visual dimensional checks as well as ultrasonic inspections over the entire body of the drill collar. Cold Rolling: Drill collar thread roots, as well as elevator recess upper radius, are cold-rolled. Cold rolling creates a compressive recess upper radius stress condition that increases fatigue life by minimizing crack initiation. Phosphate-coated or Copper Plating: All connections are phosphate-coated or copper plated to improve resistance to corrosion.

1. Scope Model DYFZ-A mechanical stage tool is a special tool used to complete the cementing operation in two times. Mainly used in the following circumstances. 1.1. Excessive injection of cement at one shot. 1.2. The formation cannot bear the gigantic fluid pressure. 1.3. Packoff special strata. 1.4. Avoid the occurrence of annual air channeling after the cementing job. 1.5. The considerable temperature difference between the upper and lower section makes it rather difficult to adjust the slurry performance. 1.6. Two-stage cementing for deviated and horizontal wells 2. Structure Model DYFZ-A mechanical stage tool mainly consists of two-stage coupling (body), shut-off baffle, first-stage plug, Free-fall opening plug and closing plug 1. An anti-rotation device is specially developed to prevent the synchronous rotation of closing sleeve and bits. 2. A particular structure is developed to prevent the possible pre-shutoff of closing sleeve. 3. In the closing sleeve of closed circulation hole, close the locking mechanism to prevent closure put on the back, to achieve permanent closure. 4. All accessories, made from premium quality rubber or aluminum material, have very good anti-rotating mechanism that makes drillout easy. 5. Free-fall opening plug and pumping-down opening plug are available to realize mechanical opening. 6. The ID. of upper/lower sub should be the same as that of casing, but smaller than that of closing sleeve, which protects the clos Specifications(in),7" Opening Pressure(Mpa),7 Closing Pressure(Mpa),5.5 Sealing Capacity(Mpa),,25 Rated Load(t),180 Connection Thread,API 7" Max.
