Cost effective – User can get good result with lower cost.

U bolt clamps are cost effective,the cost is low,but it’s poor Serviceability.

Narrow band clamp is Durability and Serviceability,the cost is much higher than U bolt clamps.

Coupler clamp is Sealability,Durability and Serviceability,the cost is highest.

Butt joint band clamp is to connect equal diameter,mainly used for trucks. It’s Serviceability.

Lap joint band clamp is similar as Butt joint band clamp but used for step pipes.
