Alloy Steel Forged Wye Fitting
A Y-shaped wye fitting forged from 8620 alloy steel for drainage or irrigation pipe branching. It is supplied in a rough condition without any machining after forging. This fitting is used in piping systems where a branch line joins the main line at an angle.
7307.99.00As-Forged Alloy Steel Sleeve Fitting
A protective sleeve forged from chromium-moly alloy steel to reinforce pipe joints, delivered in a rough condition without tooling. It is supplied as-forged with no subsequent machining. This sleeve is used to strengthen pipe connections in demanding applications.
7307.99.00Forged Alloy Steel Cross Fitting
A four-way cross pipe fitting forged from manganese alloy steel for multi-directional pipe connections in construction equipment. It is supplied as-forged with an unmachined surface. This cross fitting is used in complex piping networks requiring multiple branch connections.
7307.99.00Forged Alloy Steel Elbow Fitting
A 90-degree elbow fitting forged from alloy steel (e.g., AISI 4140), not machined or tooled after forging. It is used for connecting pipes in low-pressure hydraulic systems. This elbow is supplied in a rough-forged condition without any post-forging processing.
7307.99.00Forged Alloy Steel Reducer Fitting
A concentric reducer forged from 4130 alloy steel to connect pipes of different diameters in oilfield applications. It is supplied in a rough-forged condition without any machining. This reducer is used to transition between pipe sizes in high-pressure systems.
7307.99.00Forged Iron Pipe Bend
A forged iron or nonalloy steel pipe bend fitting, formed at a 45-degree angle to direct flow in piping systems. It is supplied in an as-forged condition without subsequent machining or tooling, which is characteristic of this tariff item. This fitting is used in drainage and venting applications where directional changes are required.
7307.99.00Forged Iron Pipe Cap
A forged iron or nonalloy steel pipe cap, used to seal the end of a pipe in pressure systems. It is supplied rough from forging without any post-forging machining, threading, or other processing. This cap is commonly used in oil field and construction piping to close off pipe ends.
7307.99.00Forged Iron Pipe Cross
A forged cross fitting made from iron or nonalloy steel, enabling four-way pipe connections in complex piping networks. It is supplied in an unprocessed forged condition without any machining or tooling after forging. This fitting is suited for rough industrial frameworks where multiple pipe branches converge.
7307.99.00Forged Iron Pipe Elbow
A rough-forged elbow fitting made from nonalloy steel, used to connect pipes at a 90-degree angle in basic plumbing systems. It remains unprocessed after forging, with no machining, threading, or other finishing operations. This fitting is ideal for rough-in plumbing in buildings where directional changes are needed.
7307.99.00Forged Iron Pipe Tee
A rough-forged tee fitting from iron or nonalloy steel, allowing a pipe branch at 90 degrees from the main line. It is unprocessed after forging, with no machining or tooling applied. This tee is used for rough-in plumbing in buildings and other basic piping applications.
7307.99.00Forged Steel Pipe Coupling
A simple forged coupling of nonalloy steel designed to join two pipes end-to-end in straight-line connections. It is a rough forging without any machining, threading, or other processing after forging. This coupling is used in various piping systems to connect pipe sections.
7307.99.00Forged Steel Pipe Nipple Blank
An unfinished forged blank for pipe nipples, made from nonalloy steel, before any threading is applied. It is in a raw forged state without any processing, used by fabricators to create custom-length nipples. The product has a solid, non-wire profile, distinguishing it from wire products.
7307.99.00Forged Steel Pipe Reducer
A forged reducer fitting of nonalloy steel that connects pipes of different diameters in piping systems. It is supplied in a rough, unprocessed forged state without any machining. This reducer is used in HVAC and water supply lines to transition between pipe sizes.
7307.99.00Forged Steel Pipe Sleeve
A rough-forged sleeve of nonalloy steel used to reinforce or couple pipe joints externally. It is supplied without any machining after forging, maintaining its as-forged surface. This sleeve is used in repair and extension applications for piping systems.
7307.99.00Forged Steel Pipe Union
A rough-forged union fitting of iron or nonalloy steel for easy pipe disconnection without cutting. It is supplied without any post-forging processing, such as machining or threading. This union is used in maintenance-heavy systems like fire sprinkler installations.
