A thread protector is used to protect the threads of a pipe during transportation and storage, can be used on Casing Pipe, Tubing, Drilling Pipe. 

They are generally manufactured from plastic or steel and can be applied to the pipe manually or automatically (by machine), and they are used frequently in the oil and gas industry to protect pipes during transportation to the oil and gas fields. 

And there are mainly 2 categories: HDPE Plastic Thread Protector, Metal Thread Protector. 

Commonly the price for plastic thread protector is lower than that of metal plastic composite protector. Because there is steel material attached on second type. For Tubing, plastic thread protector is always the choice.

Silicone (VMQ) rubber contains methyl and vinyl groups attached to the main silicone chain. Silicone O-rings are characterized by excellent resistance to temperature extremes and thermal cycling. Silicone rubber compound does not impart odor or taste, which makes it suitable for many food and pharmaceutical applications.

Standard back-up rings are used in both static and dynamic sealing. Made of materials that are resistant to pressure induced flow, the back-up ring keeps a seal from extruding into the clearance gap between mating parts.

Our back-up rings are equivalent to AN6224, AN6246, MS28774, MS28782, and MS28783 specifications.  The PTFE back-up rings are specifically cut to MS28774 specifications.  Both types of back-up rings share a common rectangular cross-section.

A cementing plug is used to separate the cement slurry from other fluids, reducing contamination and maintaining predictable slurry performance. Typically, two types of cementing plugs are used on a cementing operation.
Combination Cementing Plugs typically use in combination casing strings. It may be a standard or non-rotating plugs type. Our SKU: CSS-122 is a standard Combination Cementing Plug. All combination plugs are PDC drillable and can sustain differential pressure.
Cementing plugs from Astarn Engineering & Oilfield Supplies are constructed with selective materials resulting in reduce drill-out time, and thereby cost savings.
