People always confused about how to describe steel pipe dimensions (sizes) in correct ways, or how to clarify to seller what exactly pipe size we are going to purchase. In case any misunderstandings or a different size we purchased, that will be a big trouble.

ASTM A335 pipe (with Grade P9, P11, P22, P91 pipes) has been widely used in different industries for high temperature, high pressure services. According to market data, it is one of the most consumption alloy pipes in boiler industry, heat exchanger, power station, high and super high pressure vessels.

People always confused about how to describe steel pipe dimensions (sizes) in correct ways, or how to clarify to seller what exactly pipe size we are going to purchase. In case any misunderstandings or a different size we purchased, that will be a big trouble.

The main difference between Schedule 10 and Schedule 40 pipe is the wall thickness, which affects strength, pressure rating, and weight.

Measuring steel pipe size accurately is crucial for selection, installation, and system compatibility. Here’s a simple guide on how to measure steel pipe size step-by-step, whether for standard pipes (e.g. plumbing) or industrial use.

The strength of black iron pipe and galvanized pipe depends on their material composition and intended use. Here’s a comparison of black iron pipe and galvanized pipe strength.

Measuring galvanized pipe size involves determining its outer diameter (OD), inner diameter (ID), and nominal pipe size (NPS). Here’s how you can do it.

Pipe Schedule (SCH) is a standardized system that indicates the wall thickness of a pipe. It is used primarily for steel and galvanized pipes to ensure they meet specific pressure, strength, and durability requirements.This article will briefly introduce what is pipe schedule.

Galvanized steel pipes come in a variety of sizes, diameters, and wall thicknesses to suit different applications. The most common sizing standards are based on Nominal Pipe Size (NPS) in inches or millimeters, along with Schedule (SCH) numbers that indicate wall thickness.

Fire sprinkler systems play a crucial role in fire protection, ensuring the safety of buildings and occupants. The selection of piping material is essential for the efficiency, durability, and compliance of the system. Different types of pipes are used depending on the application, environment, and fire protection standards. Below are the most commonly used pipes for fire sprinkler systems.

Fusion Bonded Epoxy (FBE) coating is a type of protective coating widely used for steel pipes and other metal structures to prevent corrosion. It is applied as a dry powder that melts and bonds to the metal surface when heated, forming a uniform, durable, and corrosion-resistant layer.This article will briefly introduce wwhat is fusion bonded epoxy coating.

Measuring tubing for bending requires careful calculations to ensure accuracy and prevent material waste. The key factors to consider include bend radius, bend angle, and material elongation. Here’s a step-by-step guide.

To calculate the bend length of a pipe, you need to know the pipe's radius of curvature(also called the bend radius) and the angle of bend. The bend length refers to the length of the pipe along the arc of the bend, not the straight-line distance between the ends.Here’s how to calculate the bend length.

Calculating the pipe degree angle involves determining the angle at which a pipe needs to be bent or joined to fit into a specific layout. This is commonly done in plumbing, HVAC, and other piping systems. Here's a step-by-step guide to calculate the pipe degree angle.

The bevel angle for pipe welding is a crucial factor that influences the quality and strength of the welded joint. The specific angle depends on the pipe size, wall thickness, and the type of welding being performed. However, general guidelines for bevel angles are as follows.

The lifespan of galvanized pipes depends on various factors such as the quality of the galvanization, environmental conditions, and the specific use case. This article will briefly introduce how long do galvanized pipes last.

The weight of a drill pipe varies depending on its size, material, and wall thickness. Drill pipes are typically made of steel and are designed to withstand high-pressure conditions while being used in drilling operations. Here's a general guideline to give you an idea of the typical weight range.

The thickness of a Schedule 40 pipe depends on its nominal pipe size (NPS), which determines the pipe’s outside diameter (OD) and wall thickness. Schedule 40 is a designation that refers to the pipe's wall thickness, and it is commonly used for various materials, including steel and PVC. Below are the wall thicknesses for Schedule 40 steel pipes based on different nominal pipe sizes (NPS).

Measuring and bending tubing requires precision to ensure that the tubing fits correctly and performs well in its intended application. Whether you're working with metal, plastic, or other materials, the process typically involves the following steps.

P91 steel pipe is a type of alloy steel that is commonly used in high-temperature and high-pressure applications, particularly in the power generation industry. P91 steel is part of the 9% chromium, 1% molybdenum family of steels, which are designed for use in environments where high strength, oxidation resistance, and resistance to creep (deformation under stress at elevated temperatures) are essential. It is known for its ability to maintain good mechanical properties at high temperatures.

A heat number (also called a heat lot number) is a unique identifier assigned to a specific batch of steel or metal that is produced during a particular melting or heat process. It plays a crucial role in traceability, ensuring that each pipe can be linked back to the specific material batch it was made from. The heat number provides detailed information about the chemical composition, production process, and quality of the steel used in the manufacturing of pipes.
