Detailed Manufacturing Process of 140mm PVC Drilling Pipe

The production of high-quality 140mm PVC Drilling Pipe involves a sophisticated extrusion process, followed by precision machining and rigorous quality control. This ensures the pipes meet the stringent requirements of drilling applications.

Process Flow Breakdown:

1. Raw Material Preparation: High-grade unplasticized Polyvinyl Chloride (uPVC) resin is the primary material. This virgin resin is carefully selected for its molecular weight, K-value, and purity. Stabilizers, lubricants, pigments, and UV inhibitors are precisely mixed with the PVC resin in high-speed blenders to create a homogenous compound. This compounding process is critical for achieving the desired pipe properties, including strength, durability, and resistance to environmental factors.
2. Extrusion: The PVC compound is fed into a twin-screw extruder. Inside the extruder, the compound is heated and melted as it moves along the screws, which also mix and homogenize the material. The molten PVC is then forced through a die, which shapes it into a continuous pipe profile. The precise design of the die and the control of temperature and pressure are crucial for maintaining the pipe's exact outer diameter and wall thickness.
3. Sizing and Cooling: Immediately after exiting the die, the hot, pliable pipe enters a vacuum sizing tank. The vacuum helps to pull the pipe against a sizing sleeve, ensuring dimensional accuracy (OD and wall thickness) as it cools. Water sprays within the tank rapidly cool the pipe, solidifying its shape. This stage is critical for achieving the specified pipe dimensions and maintaining its circularity.
4. Haul-Off and Cutting: A haul-off unit, consisting of motorized belts, pulls the cooled and sized pipe steadily from the sizing tank. The speed of the haul-off unit is synchronized with the extruder output to maintain consistent wall thickness and diameter. Once the pipe reaches the desired length (e.g., 3m or 6m), an automatic cutting saw precisely cuts it into individual sections.
5. End Finishing (Threading/Chamfering): For drilling applications, pipe ends require precise threading to allow secure and leak-proof connections. This is typically done using CNC (Computer Numerical Control) machining. Precision CNC lathes are used to cut various thread types, such as API (American Petroleum Institute) threads, trapezoidal threads, or proprietary thread designs, ensuring optimal engagement and seal. Chamfering of the pipe ends is also performed to facilitate easier connection and protect the threads during handling.
6. Quality Control and Inspection: Throughout the entire manufacturing process, rigorous quality control measures are implemented.
   • In-line monitoring: Laser scanners continuously monitor the pipe's OD and wall thickness during extrusion.
   • Hydrostatic Pressure Testing: Samples from each batch are subjected to hydrostatic pressure testing to verify the pipe's ability to withstand internal pressure. This tests the structural integrity of the pipe wall and joints. (e.g., in accordance with ASTM D1785 or ISO 1452 standards).
   • Impact Testing: Samples are tested for impact resistance to ensure durability against external forces encountered during handling and installation.
   • Dimensional Checks: Manual checks of length, diameter, wall thickness, and thread dimensions are performed on every pipe section.
   • Material Property Verification: Tensile strength, flexural modulus, and Vicat softening temperature tests are conducted on material samples to confirm mechanical and thermal properties.
   • Visual Inspection: Each pipe is visually inspected for defects, scratches, or inconsistencies.
7. Marking and Packaging: Finally, each pipe is marked with relevant information such as manufacturer's name, size, pressure rating, production date, and applicable standards. Pipes are then bundled or crated for safe transportation, often with end caps to protect the threads.

Manufacturers adhere strictly to international standards such as ISO 1452 (Plastics piping systems for water supply) and ASTM D1785 (Standard Specification for Poly(Vinyl Chloride) (PVC) Plastic Pipe, Schedules 40, 80, and 120), ensuring that the final 140mm PVC Drilling Pipe meets global performance and safety benchmarks.
