Introduction to Steel Pipe Nipples
Steel pipe nipples are essential components in piping systems, providing secure connections between fittings, valves, and other piping elements. Available in various lengths, diameters, and materials, they ensure leakproof performance in plumbing, industrial, and hydraulic applications.
Cangzhou Hongxin Pipe Fittings Co. specializes in manufacturing highquality steel pipe nipples in carbon steel, stainless steel, and galvanized steel, offering superior durability and corrosion resistance for demanding environments.
Standard Steel Pipe Nipple Lengths
- Close Nipple (Shortest Length)
Length: Threads run nearly the entire length, leaving almost no unthreaded space.
Applications: Tight spaces where minimal length is required.
Common Sizes: 1/8″ to 4″ diameters.
- Short Nipple
Length: Slightly longer than a close nipple, with a small unthreaded section.
Typical Lengths: 1″ to 2″ (varies by diameter).
Applications: Compact installations with limited clearance.
- Standard/Long Nipple
Length: The most commonly used size, with a balanced threaded and unthreaded portion.
Typical Lengths: 2″ to 12″ (or longer for custom orders).
Applications: General plumbing, water lines, and industrial piping.
- ExtraLong Nipple (Extension Nipple)
Length: Extends beyond standard lengths for specific spacing needs.
Typical Lengths: 12″ up to 36″ (custom lengths available).
Applications: Largescale industrial systems requiring extended reach.
How to Measure Steel Pipe Nipple Length?
Total Length (TL): Measured from end to end, including threads.
Thread Engagement: The threaded portion that screws into fittings.
Unthreaded Middle Section: Present in standard and long nipples.
Example: A 6″ steel pipe nipple may have 1″ of threads on each end and 4″ of unthreaded pipe in the middle.
Material Options for Steel Pipe Nipples
- Carbon Steel Nipples
Pros: High strength, costeffective, good for highpressure systems.
Applications: Oil & gas, industrial machinery, and structural piping.
- Stainless Steel Nipples
Pros: Corrosionresistant, ideal for harsh environments (chemical, marine).
Grades: 304, 316 for enhanced durability.
- Galvanized Steel Nipples
Pros: Zinccoated for rust prevention, suitable for water supply and outdoor use.
Applications: Plumbing, fire sprinkler systems.

Frequently Asked Questions (FAQ)
Q1: What is the shortest steel pipe nipple available?
The close nipple is the shortest, with threads covering almost its entire length.
Q2: Can I get customlength steel pipe nipples?
Yes, Cangzhou Hongxin offers customcut nipples to meet specific project requirements.
Q3: Are stainless steel nipples better than galvanized?
Stainless steel offers superior corrosion resistance, making it ideal for harsh environments, while galvanized is more costeffective for general use.
Q4: How do I prevent leaks with steel pipe nipples?
Use thread sealant (Teflon tape or pipe dope) and ensure proper tightening.
Q5: What’s the difference between NPT and BSP threads?
NPT (National Pipe Thread): Tapered threads common in North America.
BSP (British Standard Pipe): Parallel or tapered threads used internationally.
