Carbon Steel Threaded Caps and Plugs

Threaded Caps and Plugs

As we know, threaded caps and plugs both have the function to seal the pipe end. However, NPT pipe cap covers pipe end to fulfill the role of sealing, while forged plugs is inserted into the pipe to realize its function.

Package of Low Temp Carbon Steel Threaded Fittings

We marked all Carbon Steel Threaded Cap Fittings with Size, Pressure, Thread Type, Material, Standard and Heat No. The workers sleeved ASTM A350 LF2 Forged Threaded Fittings into plastic bag individually, put all of them into cartons, then packed cartons in wooden case, finally bundled package with nylon rope.

Clear labels are tagged on the outside of the package for easy identification of the quantity and product I.D. Great care is taken during operation and transportation.

Inspection Step for Threaded Cap

Visual the surface of threaded cap body. Such as dents, die marks, porosity, undercuts etc.

Check the marking. Such as size, material grade, pressure rating, thread type and heat No.

Measure dimensions. Such as outside diameter, height from end to end, wall thickness.

Test Thread with Go-No Go Guage
