quality control
- Surface Quality - Product surface quality is controlled through visual inspection and other techniques to eliminate any defects.
- Dimensional Measurement - Critical dimensions like outer diameter, wall thickness, and diameter tolerances are periodically measured using dimensional gauges.
- Hydrostatic Testing - 100% of products undergo hydrostatic testing to verify strength and sealing performance.
- We follow strict quality control from raw material selection to finished product dispatch, following standards, to ensure every piece of pipe complies with customer specifications for reliable application in downhole tools, sucker rod pumps, etc. Customers are welcome to witness our quality control processes first-hand at our factory.
Features
1. High tolerance dimensional accuracy, with product accuracy controlled within ±0.05mm. The inner and outer walls are smooth and have no oxide layer on the surface.
2. Excellent overall performance, it can withstand high pressure, cold bending, flaring, and compression without cracking or wrinkling. They can be used for various complex deformations and mechanical processing.
3. The promotion and application of seamless pipes can save steel, improve processing efficiency, reduce processing steps and equipment investment, save costs, and greatly save mechanical processing time.
Advantages of using Cold Rolled Pipe
● Improved Surface Finish: Cold rolling provides these pipes with a smooth surface, free from scaling and other imperfections.
● Tight Dimensional Tolerances: The pipes are renowned for their precision in size, uniformity, and concentricity, which is due to the controlled rolling process and lack of heating during production.
● Increased Strength: Cold worked steel has higher yield strength and tensile strength compared to hot-rolled steel of the same grade and size. Because of strain hardening, the metal becomes much stronger and harder.
● Enhanced Durability: The process can also enhance the durability of the pipes, making them more resistant to wear and tear over time.
● Potential for Fine Detailing: The improved strength doesn't compromise the ability of the material to be detailed finely, allowing for intricate shapes and patterns to be maintained during fabrication.
● Better Mechanical Properties: Due to the cold-working and hardening processes, cold-rolled pipes generally have better mechanical properties, such as toughness and load-bearing capacity.
● Increased Structural Integrity: Cold-formed designs yield products with increased rigidity and structural integrity not often matched by equivalent hot-formed products.
● Customizable Shape and Sizes: The manufacturing process allows for a variety of shapes, sizes, and thicknesses to be created, providing customizable options for specific applications.
● Energy Efficiency: The process is generally more energy-efficient than hot rolled as it does not require the steel to be heated at high temperatures.
● Environmentally Friendly: As mentioned, lower processing temperatures mean lower energy consumption, translating into reduced emissions and a smaller environmental impact.
Applications
(1) Sucker Rods - Rods have the high tensile strength to withstand heavy dynamic and static loads during artificial lift pumping. The precision dimensions ensure proper coupling connections.
(2) Pump Barrels - Seamless pipe makes excellent pump barrels that can resist deformation under pressure. The smooth interior surface reduces fluid friction.
(3) Pony Rods - Cold rolled pony rods provide a cost-effective alternative to sucker rods for deeper well applications requiring additional rod strength.
(4) Crossovers - Rolling allows sizing crossover subs with tapered threads on both ends to join piping of different diameters.
(5) Stabilizers - Cold rolled heavy wall pipe is ideal for milling and machining downhole stabilizers used to center tools and reduce friction.
