Slip on Set Screw Ductile Iron Stop Collar
DIC is a Supplier and Exporter of Slip-on Set Screw Ductile Iron Stop Collars. 
It has welded on one side. Stop collar has premium quality bows with a high restoring force and uniform hardness. The slip-on centralizers come with a direct installation pipe denoted for slipping on. It has high tensile strength, absorption shock value, and great impact value. The welded centralizers can never be smooth because of a single-piece centralizer.
The welding can be overlapped and little exposed. It allows friction to fluid during running in the hole, but the single-piece centralizers have a corner radius that allows the fluid to pass due to low friction. Any special sizes can be available upon request.
Material: Stainless
- These Stop Collars undergo a special Phosphate coating process to restrict from rust and then coated with special Polyester Powder.
