Tubes, pipes and hoses, and fittings therefor, of plastics

cpc code 3632 covers the production of tubes, pipes, hoses, and associated fittings made from plastics. This industry plays a vital role in the broader manufacturing and infrastructure sectors, providing essential components for a wide range of applications, from plumbing and construction to automotive and industrial equipment. The versatility and durability of plastic-based piping systems make them an increasingly popular choice over traditional materials, contributing to their growing importance in the global economy.

The main production techniques used in this industry involve various plastic processing methods, such as extrusion, injection molding, and blow molding. Extrusion is a common process for manufacturing continuous lengths of pipes and tubes, where molten plastic is forced through a die to create the desired shape and profile. Injection molding is often used for producing complex fittings and connectors, where the plastic is injected into a mold cavity and allowed to solidify. Blow molding is another technique employed for creating hollow plastic parts, such as hoses, where the plastic is inflated into a mold to take on the desired form.

The primary inputs required for the production of plastic tubes, pipes, and hoses include thermoplastic resins, such as polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). These raw materials are supplemented by various additives, such as stabilizers, colorants, and reinforcing agents, which are used to enhance the performance and characteristics of the final products. Additionally, the industry relies on specialized machinery, including extruders, injection molding machines, and blow molding equipment, as well as skilled labor to operate and maintain these production systems.

The main outputs of this industry are the various types of plastic tubes, pipes, hoses, and associated fittings. These products are widely used in a variety of applications, including 4220 Plumbing, heating, and air-conditioning equipment, 3334 Industrial machinery, 3361 Motor vehicle manufacturing, and 2371 Construction. The versatility and adaptability of plastic-based piping systems make them a popular choice across numerous industries, contributing to their growing demand and importance in the global marketplace.
