Galvanization involves coating iron or steel with zinc to prevent rusting. While this treatment extends the life of pipes, it also alters their surface texture. The roughness created by the galvanization process can increase the friction factor compared to smooth-walled pipes. This increase implies greater energy requirements for pumping fluids through galvanized pipes, particularly in systems that rely on water or other low-viscosity fluids.

Rubber tapes are an essential component in many industries, including construction, automotive, and electrical fields. These tapes are made from different types of rubber and used for various applications, such as sealing, insulation, and packaging. Here are some of the most commonly used rubber tapes:
1. Silicone Rubber Tape: This type of rubber tape is highly resistant to heat, cold, and moisture, which makes it ideal for electrical and electronic applications. It can also be used for sealing and insulating.
2. Butyl Rubber Tape: Butyl rubber tape is known for its high adhesive strength and excellent sealing properties. It is often used in the construction industry for sealing roofs, windows, and doors.
3. EPDM Rubber Tape: EPDM (ethylene propylene diene monomer) rubber tape is highly resistant to UV radiation and weathering, which makes it ideal for outdoor applications. It is often used for sealing or protecting joints, roofs, and facades.
