Tsarin:

Haɗaɗɗen gyaran kafa guda ɗaya:
Consists of a single-piece, C- or U-shaped, rigid metal shell (usually two halves joined and bolted together). A layer of elastic sealing material (such as rubber) is pre-installed or placed on-site inside the shell. Tightening the bolts on the shell clamps it against the leaking pipe, squeezing the sealing material inside and causing it to deform, filling the leak and forming a tight seal against the pipe's outer wall.

Haɗin gyare-gyare mai ɗaure biyu:
Consists of two separate, usually narrow, rigid metal shells (clamps). A thick, specially designed elastic gasket (usually with a rectangular cross-section) is sandwiched between the two shells. Tightening the long bolts passing through the two shells pulls the two shells together, forcing the gasket trapped between them. Under the intense axial pressure, the gasket expands and deforms radially, tightly filling the leaking pipe and firmly fitting against the pipe's outer wall, forming a seal.

Ƙirƙirar shigarwa da farashi:

Single Clamp Patcher: Relatively simple in structure, generally quicker to install, and generally lower in cost. Double-clamp repairer: The structure is slightly more complicated (two clamps and a pad in the middle), and careful alignment and uniform tightening of bolts are required during installation. The operating requirements may be slightly higher, and the cost is usually higher than the single-clamp repairer.
