Application Fields

The Foundation for Reliable Piping Systems:

Chemical & Process Industries: Creating durable, corrosion-resistant pipelines for chemical transfer and processing.

Oil & Gas: Used in instrumentation lines, hydraulic systems, and process piping where high pressure and durability are critical.

Food, Beverage & Pharmaceutical: A hygienic solution for connecting pipes in utility lines (e.g., steam, compressed air, water).

Marine & Shipbuilding: The ultimate stainless steel pipe fittings for resisting saltwater corrosion on ships and offshore platforms.

Pneumatics & Hydraulics: Building robust manifold blocks and connecting high-pressure lines.


Technical & Selection Guide

Understanding Thread Types

Choosing the correct thread is critical for a leak-proof seal.

NPT (National Pipe Taper): The North American standard. It is a tapered thread that creates a seal by the threads wedging together. A thread sealant is required.

BSPT (British Standard Pipe Taper): Similar to NPT but with a different thread angle. A thread sealant is required.

BSPP (British Standard Pipe Parallel): A straight (parallel) thread. It does not seal on the threads themselves but relies on a gasket, O-ring, or washer against the shoulder of the fitting to create a seal.


FAQ

Frequently Asked Questions

Q: What is the difference between a nipple and a coupling?

A: A nipple is a short piece of pipe with male (external) threads on both ends. A coupling is a short fitting with female (internal) threads on both ends. They are used to connect two male-threaded components.

Q: What is the difference between a plug and a cap?

A: A plug has male threads and is used to seal a female-threaded port. A cap has female threads and is used to seal the end of a male-threaded pipe.

Q: Why use 316 stainless steel instead of 304 or brass?

A: 316 stainless steel offers superior corrosion resistance compared to both 304 SS and brass, especially against chlorides (like saltwater) and a wider range of chemicals. It is the preferred choice for marine, chemical, and food-grade applications.
