TIS 216-2524 (released in 1981) is a technical specification for PVC-U (Unplasticized Polyvinyl Chloride) pressure piping fittings developed by the Thai Industrial Standards Institute (TISI), applicable to PVC-U fittings for socket or adhesive connections in water supply, irrigation, and other pressure fluid delivery systems.

This standard specifies the material requirements, dimensional tolerances, physical properties, testing methods, and markings for PVC-U fittings, ensuring the safety and durability of the product under pressure conditions.

Rigid PVC (Polyvinyl Chloride) conduit is an essential component in modern electrical installations, providing a lightweight, durable, and corrosion-resistant solution for protecting electrical wiring. Understanding the different types of rigid PVC conduit can help you select the best option for your specific needs.

Often working behind the scenes, this versatile and reliable solution plays a crucial role in ensuring the safety and longevity of your wiring systems. From protecting delicate cables from physical damage to safeguarding against environmental hazards, Schedule 80 PVC conduit is an unsung hero of construction projects both big and small.

Schedule 40 PVC conduit is not only a master of physical protection, but also a wise expert in environmental protection.

Faced with the challenges of harsh environments such as humidity, corrosion, and even fire hazards, Schedule 40 PVC conduits have built an indestructible barrier for cables with their excellent weather resistance and flame retardant properties.
