As one of the largest pipe manufacturers, ERA Pipe fittings has an annual production capacity of 1,600,000 Tons. How is UPVC pipe produced? Now let me introduce you.

Producing UPVC pipes involves several steps in a manufacturing process. The process can vary depending on the specific equipment and technology used by the manufacturer, but the general steps include:

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.

It's essential to follow strict quality control procedures to ensure that the UPVC pipes produced meet industry standards and regulations. The specific manufacturing process may vary based on the intended application and the size and type of UPVC pipes being produced.
