What Are the Different Types of Pipe Threads?

Pipe threads are essential for securely connecting pipes and fittings in fluid and gas systems. Selecting the correct thread type is critical for compatibility, sealing, and long-term durability. This article explores common pipe thread types, their applications, and how to choose the best fit for your needs. JIANZHI offers a wide range of pipe fittings, including customized BSP connection type solutions, tailored to meet the unique demands of New Zealand industries.


Understanding Pipe Thread Types


Pipe threads are categorized based on their design and functionality:


● Sealing Threads: Create a tight seal for leak prevention, often using thread deformation or a sealing agent.

● Fastening Threads: Provide mechanical connections and rely on gaskets or O-rings for sealing.


Common Pipe Thread Types


1. BSP (British Standard Pipe)

BSP threads are highly popular in New Zealand for their reliability and versatility.


BSPP (Parallel): Requires a washer or O-ring for sealing.

BSPT (Tapered): Seals through thread compression.

Applications: Widely used in water systems, plumbing, and hydraulic systems.


2. NPT (National Pipe Thread)

A U.S. standard widely adopted globally, including some industrial applications in New Zealand.


Design: Tapered threads with a 60-degree angle.

Sealing: Thread deformation ensures a strong seal.

Applications: High-pressure gas, oil, and hydraulic systems.


3. Metric Threads

Metric threads are used extensively in automotive and precision machinery.


Design: Thread pitch and diameter are measured in millimeters.

Applications: Engineering and manufacturing systems requiring international standardization.


4. ISO G Threads

ISO G threads are parallel threads that work well in low-pressure systems.


Sealing: Requires a gasket or O-ring for effective sealing.

Applications: Suitable for plumbing and fluid transport systems.


Why Choosing the Right Pipe Thread Type Matters


New Zealand’s industries, ranging from agriculture to construction, demand durable, leak-proof, and compatible pipe fittings. Choosing the wrong thread type can lead to:
