FAQ
Q1: What are small quick locks used for?
A: RTT's small quick locks are designed for trenchless pipeline rehabilitation. They provide fast, mechanical sealing of cracks, leaks, or joint defects in small-diameter pipes—typically DN150 to DN300.
Q2: What pipe materials are compatible with these locks?
A: They are suitable for use in concrete, clay, PVC, and HDPE pipelines. The stainless steel band and EPDM rubber seal ensure secure adhesion across varied pipe surfaces.
Q3: How are the quick locks installed?
A: Installation is trenchless and fast. The lock is positioned using a robotic crawler or manual push rod, then expanded to press the seal tightly against the pipe wall—no curing or adhesives required.
Q4: What sizes are available?
A: RTT offers small quick locks in multiple diameters, typically ranging from DN150 to DN300. Custom sizes can be produced upon request.
Q5: Are these locks resistant to corrosion and chemicals?
A: Yes. The stainless steel structure and EPDM seal are highly resistant to corrosion, wastewater chemicals, and temperature fluctuations.
Q6: Can these locks be used in pressurized pipelines?
A: They are primarily designed for gravity-fed systems. For pressurized applications, RTT recommends consulting with our technical team for reinforced solutions.
Q7: What is the expected service life of a quick lock?
A: With proper installation, each lock offers a service life of 20+ years, backed by RTT's quality assurance and field-tested durability.
