"Pipe & Tube Nominal Bore (NB) Pipe 304 Pipe Sch 10s & Sch 40s" refer to a variety of stainless steel pipes classified by their nominal bore size, material grade, and schedule number. Here's a detailed breakdown of each component:
Nominal Bore (NB):
Definition: Nominal Bore (NB) refers to the approximate inner diameter of the pipe. It's a traditional term used in the UK and other countries to indicate the size of the pipe.
Usage: The NB size is important for matching with fittings, valves, and other components in a piping system.
304 Stainless Steel:
Material Grade: 304 stainless steel is a widely used austenitic steel known for its good corrosion resistance, weldability, and formability. It's suitable for a variety of applications, including kitchenware, piping, and architectural moldings.
Characteristics: It contains 18% chromium and 8% nickel, offering a good balance of strength and corrosion resistance.
Schedule Number (Sch 10s & Sch 40s):
Sch 10s: This schedule number refers to a wall thickness that is relatively thin. It is typically used where pressure requirements are lower and where flow efficiency is more critical.
Sch 40s: A thicker wall compared to Sch 10s, designed to handle higher pressure. It is commonly used in applications requiring a robust pipe that can withstand higher internal pressures.
Applications:
304 Pipe in Sch 10s: Ideal for less demanding applications where flow efficiency is key, such as in sanitary or architectural applications where high pressure is not a factor.
304 Pipe in Sch 40s: More suited for applications that require durability and ability to handle higher pressures, such as in water supply, chemical, and petrochemical industries.
This classification system provides a clear way to specify and understand the type of pipe needed for various applications based on internal diameter (NB), wall thickness (schedule), and material grade (304 stainless steel), ensuring compatibility and efficiency in system design and implementation.
