How to produce UPVC pipe?

• Raw Material Preparation: The first step is to prepare the raw materials. UPVC pipes are made from Unplasticized Polyvinyl Chloride resin, which is a granular form of PVC. Other additives and stabilizers may also be mixed in to enhance specific properties of the pipes.
• Mixing and Compounding: The UPVC resin and other additives are mixed together in precise proportions to create a homogenous compound. This compound is then heated and melted in an extruder to form a molten mass.
• Extrusion: The molten UPVC compound is fed into an extrusion machine. The machine uses a screw mechanism to push the molten material through a die, which gives the pipe its desired shape and size. As the material exits the die, it is cooled rapidly using water to solidify into a pipe shape.
• Sizing and Calibration: After the extrusion process, the UPVC pipe is passed through a sizing and calibration system. This ensures that the pipe has the correct dimensions and meets the required tolerances. The pipe is then cut to the desired length.
• Cooling and Cooling Tanks: The newly formed UPVC pipes pass through cooling tanks to further solidify and stabilize their shape.
• Marking and Printing: Some UPVC pipes may undergo printing or marking processes to indicate their specifications, brand, or other relevant information.
• Quality Control: Throughout the manufacturing process, quality control checks are conducted to ensure that the UPVC pipes meet the required standards for strength, dimensions, and other properties.
• Packaging and Storage: The finished UPVC pipes are then packaged and stored in a suitable environment until they are ready for distribution and sale.

How to produce UPVC fittings？

• Raw Material Preparation: The first step is to procure the raw materials needed for UPVC fittings production. The primary material is UPVC resin, which is a rigid and durable form of PVC that does not contain plasticizers. Additionally, additives, stabilizers, and pigments may be required to enhance the material's properties and add color.
• Material Mixing: The UPVC resin is mixed with the necessary additives and stabilizers in precise proportions. This process is often carried out in a high-speed mixer to ensure uniform distribution of the additives throughout the material.
• Extrusion: After the material mixing, the UPVC compound is fed into an extrusion machine. The extruder heats the material and forces it through a specially designed die to shape the fittings. The die imparts the desired shape to the UPVC, such as pipes, elbows, tees, couplings, etc.
• Cooling and Sizing: As the UPVC comes out of the extruder, it goes through a cooling process to set its shape. Various sizing tools and fixtures are used to ensure the fittings' dimensions meet the required standards.
• Cutting and Trimming: Once the fittings have cooled and solidified, they are cut and trimmed to the desired length and shape. This step helps to remove any excess material and achieve smooth edges.
• Quality Control: Throughout the entire manufacturing process, strict quality control measures are implemented to check for defects, dimensional accuracy, and material consistency. This ensures that the final UPVC fittings meet the required standards and specifications.
• Packaging: After passing quality control, the UPVC fittings are packaged appropriately for storage and distribution.

How to Test UPVC pipe fitting in factory?

• Dimensional checks: Daily measurements are taken to verify the fittings' dimensions, such as length, diameter, wall thickness, and angles. This ensures that the fittings are manufactured within the specified tolerances.
• Visual inspection: Fittings are visually inspected for any surface defects, discoloration, cracks, or irregularities that may affect their performance or appearance.
• Tensile strength test: This test assesses the maximum amount of tensile (pulling) force the fittings can withstand before breaking. It helps determine the fittings' structural integrity and suitability for their intended applications.
• Pressure testing: Fittings may be subjected to pressure tests using water or air to check their ability to hold specific pressure levels without leakage or deformation.
• Impact resistance test: Some fittings may undergo impact tests to evaluate their resistance to sudden impacts, ensuring they can withstand accidental damage.
• Chemical resistance test: This test assesses the fittings' ability to withstand exposure to various chemicals commonly found in plumbing systems without degradation.
• UV resistance test: Certain applications, such as outdoor installations, require fittings with good UV resistance. UV testing helps determine the fittings' ability to resist degradation caused by prolonged exposure to sunlight.
• Hydrostatic pressure test: The fittings may be subjected to a hydrostatic pressure test to evaluate their resistance to internal pressure when used in water supply systems.
• Flammability test: This test checks the fittings' reaction to fire, verifying their fire resistance and compliance with fire safety regulations.
• Color consistency: If the fittings are produced in various colors, color consistency tests ensure that the hues match the specified standard.
• Heat deflection temperature test: This test determines the temperature at which the fittings start to deform under load, helping establish their maximum operating temperature.
• Flow rate testing: In case of complex fittings with flow restrictions (e.g., bends), flow rate testing ensures that they do not significantly hinder fluid flow through the system.
