In piping systems, makeup nipples serve as connectors between pipe sections. They have different sizes and shapes to suit specific needs. So they can be used in various industrial projects and sectors, such as oil and gas distribution and water supply where selecting the right nipple is critical for efficiency and safety. The variety of materials and designs available to choose from needed for different applications.
Pipe nipples are short lengths of pipe, usually with threaded ends. They are used to connect two other fittings or pipes. There are some types of pipe nipples, each designed for specific applications and environments. Here are the common types:
Close Nipple: A short piece of pipe, with male threads on both ends. It has no significant length between the threads, making it ideal for connecting two fittings closely together.
Regular Nipple: Longer than a close nipple, but it still has male threads on both ends. It is used when a bit of space is needed between the connected fittings.
Long Nipple: A long nipple, it is similar to a regular nipple but is even longer. It is used when more distance is required between connected fittings.
Reducing Nipple: A reducing nipple has different diameters on each end, allowing the connection of pipes or fittings of different sizes.
Hex Nipple: Has a hexagonal shape in the middle, allowing for easier gripping with a wrench. It typically has male threads on both ends.
Swage Nipple: Has a tapered design that allows it to connect two different pipe sizes. It can have male threads on both ends or one end may have a different fitting type.
Barrel Nipple: A cylindrical component, it is usually longer and can be used in applications requiring a straight connection between two fittings.
Socket Nipple: Has female threads on one end, and male threads on the other. That allows it to connect to a fitting with male threads.
Screwed Nipple: Similar to a close nipple, but may vary in length. It is often used in applications where a simple connection is needed.
Pipe Nipple with Flange: Some pipe nipples come with a flange on one or both ends. It allows for a bolted connection to another component. (e.g. Qingdao Fluido's Steel Pipe Nipple BS EN10241)
When selecting a pipe nipple, it’s important to consider the material (such as steel, stainless steel, etc.), the size, and the application to ensure compatibility and safety.

ASTM Standards
ASTM A733: This standard specifies requirements for welded and seamless carbon steel pipe nipples used in plumbing or piping systems. The standard covers the production, dimensions, threading, and other specifications for pipe nipples.
ASTM A307 – Standard Specification for Carbon Steel Bolts and Studs, and Threaded Rod. This standard covers carbon steel bolts and studs made to the grades A, B, and C. Threaded rod is also included in the standard. These fasteners are for general purpose applications and are not normally used at high-stress levels or high or low temperatures.
The ASTM A106 standard provides guidelines for seamless carbon steel pipe applications, and it typically used in high-temperature services for the construction of power plants, refineries for processing oil and natural gases, and the construction of pump, sugar and paper mills. These are portable steel pipes with end connections. Such pipes are suited for large suction/delivery pumps, heated village water supply pumps or pipelines, and plant drains. However, steel pipes are sensitive to high temperatures; it can degrade the strength of the material and even make it more prone to cracking and become brittle.
ANSI Standards
ANSI/ASME B1.20.1: This standard governs pipe threads, general purpose (inch). It provides specifications for the dimensions and design of threads used on pipe joints, specifically taper pipe threads for pressure-tight joints.
API Standards
API 5L: The line pipes used in petroleum and natural gas industries. API 5L pipes are available in both seamless and welded varieties and are used to transport oil, gas, and water in pipeline systems.
ISO Standards
ISO 7-1: The pipe threads where pressure-tight joints are made on the threads. It specifies requirements for the design and dimensions of taper threads typically used in water, gas, and steam installations.
NPT and BSPT Standards
NPT (National Pipe Thread): NPT is a U.S. standard for tapered threads used to seal pipes by making them pressure-tight. It is commonly used in plumbing and industrial piping applications.
BSPT (British Standard Pipe Taper): BSPT— is a thread standard for pipes used mostly in the United Kingdom and other Common wealth countries. Like NPT, BSPT is a tapered thread, which means that whenever it is employed, the male and female threads are driven against one another: they g and wedge together, forming a tight pressure seal, pressure tight seal. Like a fitting used with NPT threads, one using BSPT threads cannot be coupled when it is already installed.
