What Is a Close Black Steel Nipple?

A close pipe nipple is very short with threaded ends that meet at the center with little to no unthreaded section.

Also referred to as a “running nipple”, it is the most compact pipe nipple.

It is the go-to solution when two fittings must be connected with almost no gap between them.

Our close black carbon steel nipples have a characteristic dark oxide surface finish that provides basic corrosion resistance.

They are produced in strict conformance with ASTM A733 and ASME B1.20.1 thread standards.

Close Nipple vs Standard Pipe Nipple

The main difference between a close nipple and a standard pipe nipple is the exposed pipe body length.

A standard pipe nipple has visible unthreaded pipe, while a close nipple is almost completely threaded.

This design reduces the installation distance between fittings and makes it more compact.

Available Thread Types

We manufacture threaded pipe nipple products in multiple international thread standards:

  • NPT pipe nipple for North American markets
  • BSP pipe nipple for general international applications
  • BSPT threaded pipe nipple for pressure-tight sealing systems

Custom thread combinations and special dimensions are also available for OEM and industrial projects.

Manufacturing Information

As a pipe nipple manufacturer, we supply black steel pipe nipple products to distributors and wholesalers.

In addition to close nipples, we also manufacture:

  • Threaded one-end pipe nipple
  • Long screw pipe nipple
  • Barrel nipple
  • Seamless pipe nipple
  • Custom threaded pipe fittings

OEM marking, custom packaging, and bulk production are supported.

What Is a Long Black Steel Nipple?

A long nipple (also known as a barrel nipple) is a pipe nipple with an extended unthreaded center section between two externally threaded ends. The exposed center section provides a practical grip point for tools during installation and allows precise spacing between connected fittings. Unlike close nipples, long nipples offer flexibility in pipeline layout where a specific distance must be maintained between two threaded connections.

Our long black steel nipples are cut and threaded from black carbon steel pipe, offering the same robust performance as our other nipple types with the added benefit of adjustable center length.

Custom lengths can be produced to meet specific project requirements.

Q: What does “black” finish mean on pipe nipples?

A: Black pipe nipples have a black sand blast surface applied to the center body, providing basic surface protection and a clean appearance. Unlike galvanized nipples, they are not intended for direct water contact or outdoor exposed applications.

Q: Are black pipe nipples suitable for gas lines?

A: Yes. Black carbon steel pipe nipples are the standard choice for natural gas and propane distribution lines in residential and commercial installations, as galvanized coatings can flake and cause issues in gas systems.

Q: Can I order mixed sizes in one shipment?

A: Yes, we support mixed-size orders and container-load shipments combining multiple sizes and specifications.

Q: What is the difference between black and galvanized pipe nipples?

A: Black nipples are used primarily for gas, steam, and industrial applications. Galvanized nipples have a zinc coating for corrosion resistance and are preferred for water supply and outdoor use.

What Is a TOE Black Steel Nipple?

A TOE nipple — short for Threaded One End — is a pipe nipple with external threads on one end only.

The opposite end is left with a plain, unthreaded bore, designed for butt welding directly onto pipe or equipment.

This configuration is essential when one connection point requires a threaded fitting while the other side requires a permanent welded joint, eliminating the need for additional weld couplings or adapters.

TOE black steel nipples are commonly specified in oil & gas, petrochemical, and industrial process piping where a combination of threaded and welded connections exists within the same pipeline system.

Product Specifications

Parameter Details

  • Industrial process piping – Where permanent welded joints meet removable threaded connections
  • Power generation – Boiler and pressure vessel nozzle fabrication
  • Marine & offshore – Piping systems requiring welded integrity with threaded accessibility
