Features

• The drilling rigs can fully meet the well-drilling process requirements by adoption of flexible driving designs- mechanical drives (high-speed diesels, hydraulic transmission box, angle gear box or middle-speed diesel hydraulic transmission, chain combination box), compound transmission and electrical drives (VFD or SCR) etc.
• The whole unit is very compact and a quick whole transportation and installation of the whole drilling rig can be realized due to a utilization of a skid-mounted structure. In addition, the drilling rig requires a small working site due to its high integration and compact configuration.
• Masts and substructures have various structures, such as: perpendicular-hoist sectional mast, whole-hoist K-type mast, telescopic substructure, spirally hoisted substructure and folding - frame substructure.
• A standard and module design and various ways of combination have been adopted in order to boost up the universal and exchangeable performances of the drilling rigs and to meet the user’s different requirements.
• Disc brake or band brake can be applied as main brake and air brake or FDWS brake can be used as auxiliary brake and the energy-consumption braking can be available for electrical-drive-rig auxiliary brake. The drawworks can be equipped with bit-feed motor and control system.
• The Internet and communication techniques have been used on the drilling rigs, which can realize an integral display for power, air control, hydraulic control, and monitoring and the intellectual and safe control of the driller.
• The perfect configurations of the solid control system, well control system, high-pressure pipe manifold system, the generator house, the engine pump house, doghouse and other auxiliary facilities can meet the user’s different requirements. Safety and inspection measures are strengthened under the guidance of the design concept of “Humanism Above All” to meet the requirements of HSE.

Drill pipe is in accordance with API SPEC 5D, it can be divided into two groups:

• Group 1- Grade E drill pipe
• Group 3- All high strength grades of drill pipe.(Grades X-95, G-105, S-135)

Note: A the minimum elongation in 2 in.(50.8mm) shall be that determined by the following formula:

• e=625,000A0.2/U0.9
• where e = minimum elongation in 2 in (50.8 mm) in percent rounded to nearest 0.5%.
• A = cross-sectional area of the tensile test specimen in square inches, based on specified outside diameter, or nominal specimen width, and specified wall thickness rounded to the nearest 0.01 in.2, or 0.75 in.2, whichever is smaller.
• U = specified tensile strength, psi.

Note:

See Table 5 in API SPEC 5D for minimum elongation values for various size strip tensile specimens and grades. The minimum elongation for either round bar tensile specimen (0.350-in. diameter with 1.4 -in, gauge length and the 0.500-in. diameter with 2.00-in. gauge length) shall be that shown in Table 5 for a cross-sectional area "A" of 0.20 in.2.

Our plant has CQC authorization for manufacturing DSAW Helical Seam Steel Line pipe in diameters ranging from 8.5/8" to 60", in thickness from 5mm to 18mm and Steel Grade up to and including GB/T9711. It has the capability to manufacture pipes up to 90". The production capacity of Pipe Plant is 90,000 tons per annum.

Spiral Welded Steel Pipe Process

Coils are loaded on the decoiler of the Spiral Pipe machine. The strip is straightened and edges are milled to desired joint geometry. The strip is guided into a forming station, where it is formed to produce a cylindrical hollow body at a predetermined forming angle, ensuring proper welding gap between the abutting edges. Inside, and later, outside welding is performed by an automatic submerged arc process.

Pipes are cut to a predetermined length by an automatic plasma arc cutting device. After accomplishment of inside and outside welding, while on the production machine full length of pipe is examined by automatic ultrasonic unit with the help of 8 probes, 4 for checking plate defects and 4 for checking welding defects. Flux and slag from inside the pipes is cleaned. Pipes are inspected for any visual defects. Fluoroscopic inspection of pipes presents the entire spiral seam on visual display for analysis of all the ultrasonic indications for defects, if any, in the weld seam.

At the end facing machine both ends of pipes are machined to suit the joint to be used on the pipe line. Each end is worked separately. Each pipe is hydrostatically tested to a given pressure as per API 5L specification or other desired standard. At the end X-ray station radiographs are taken at weld seam for each pipe end to a distance of 4". Every length of pipe is subjected to a rigorous check at the final stand - before it is accepted by the quality control department.
