ASA/ ASME/ ANSI B36.19 Duplex Pipe Weight, Dimensions Chart in mm, kg, PDF online

Duplex pipes are critical parts of many industrial piping systems, especially in applications where resistance to corrosion and high strength are necessary. These pipes are made from duplex stainless steel, which is a family of stainless steel that combines the properties of both austenitic and ferritic stainless steels. Duplex stainless steel pipes are highly considered for their corrosion resistance, mechanical strength, and durability. Duplex pipes are mainly made from duplex stainless steel grades, with common grades being 2205 (UNS S32205/S31803) and 2507 (UNS S32750). These grades normally consist of around 50% austenite and 50% ferrite phases. You can find all the information on these grades in the weight and dimensions chart PDF.

Duplex pipes come in various sizes to accommodate and work with different pipe diameters and system requirements. They are available in a wide range of dimensions and thicknesses. Duplex pipe is manufactured in accordance with a variety of standards, including ASTM A790, ASTM A815, and ASME B36.19, to ensure quality and compatibility with piping systems. Detailed presentation of these standards and specifications is provided in duplex pipe weight and dimensions PDF chart below. Duplex pipes find usage in various industries where corrosion resistance, strength, and reliability are critical. Common applications include oil and gas exploration and production, chemical processing, desalination plants, pulp and paper production, and offshore platforms.

Basic Duplex Pipe types

The basic duplex pipe types are:

• Seamless duplex pipe

  These pipes are manufactured without any weld seams and are typically used in high-pressure and high-temperature applications. Seamless duplex pipe dimensions chart PDF displayed below for accurate readings.

• Welded duplex pipe

  Welded pipes are manufactured by joining duplex stainless steel sheets or plates using welding techniques. They are commonly used in less challenging situation or where large-diameter pipes are needed. Welded duplex pipe weight chart PDF given in mm and kg.

Duplex Pipes Properties

The Duplex pipe properties are:

1. Excellent strength and toughness
2. Exceptional corrosion resistance
3. Weldability
4. Better exhaust resistance
5. Better temperature resistance
6. Cost-effective
