ASME B16.9 ASTM 420 WPL6 Carbon Steel Butt Welded Equal Tee 1/2 Inch to 48 Inch SCH40 for Industry Practices
Introduction:
We, Shaanxi Peter International Trade Co., Ltd, is one of the leading manufacturers, suppliers, and exporters of ASME B16.9 equal tee butt weld fittings in China. With over 20 years of industry experience, we have established ourselves as a trusted manufacturer of high-quality butt weld fittings that meet the stringent requirements of the ASME B16.9 Standard.
The ASME B16.9 standard specifies the design, dimensions, and material requirements for factory-made wrought butt-welding fittings, including straight tees. These fittings are commonly used in various industries, including plumbing, oil and gas, chemical, and power generation, to facilitate the branching-off of pipelines or the creation of new connections in piping systems. They are typically made from materials such as carbon steel, stainless steel, or other alloys, depending on the specific application and the fluid or gas being conveyed.
Description of ASME B16.9 Carbon Steel Butt Welded Equal Tee:
The ASME B16.9 Equal tee is a type of pipe fitting that is designed to create a perpendicular connection to a pipe. It is named "tee" because its shape resembles the letter T when viewed from the side. The tee fitting has three openings, with one being the "run" and the other two being the "branches." The run is the straight section of the tee, while the branches are the two openings at 90-degree angles to the run.
The ASME B16.9 carbon steel butt welded equal tee with a size range of 1/2 inch to 48 inch and SCH40 (Schedule 40) specifications, is commonly made from ASTM A234 WPB material. ASTM A234 WPB is a standard specification for carbon steel pipe fittings of seamless and welded construction. It is commonly used for moderate and high temperature services. The specified size range for the equal tee is from 1/2 inch to 48 inches. This indicates that the tee is available in various sizes to accommodate different pipe diameters.The term SCH40 refers to the pipe's schedule or wall thickness. SCH 40 is a common standard for pipe wall thickness used to indicate the thickness and pressure capacity of pipes. It is a medium wall thickness standard commonly used for carbon steel pipes. The equal tee is designed for butt welding, where the ends of the tee and the pipes are beveled and then welded together. Butt welding offers a strong and leak-resistant joint.
Carbon steel butt welded equal tees, are widely used in industrial applications where a branch connection is required. They are suitable for various industries, including oil and gas, petrochemical, power generation, and more. The ASTM A234 WPB material and SCH80 specifications ensure the tee's strength, durability, and compatibility with carbon steel pipes of corresponding sizes and schedules.
Description of ASTM A420 WPL6:
ASTM A420 WPL6 is a grade of material specified in the ASTM A420 standard for pipe fittings made of wrought carbon steel and alloy steel intended for low-temperature service.
Composition: ASTM A420 WPL6 fittings are made from carbon steel or low-alloy steel with a specified chemical composition that includes elements such as carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, and other alloying elements.
Mechanical Properties: The mechanical properties of ASTM A420 WPL6 fittings are designed to meet specific requirements for tensile strength, yield strength, elongation, and impact toughness at low temperatures. These properties ensure the fittings can withstand the stresses and conditions encountered in low-temperature service applications.
Low-Temperature Service: ASTM A420 WPL6 fittings are specifically intended for use in environments where low temperatures are a consideration. They are suitable for applications in industries such as oil and gas, petrochemical, and cryogenic systems where the piping systems operate at temperatures below ambient levels.
Impact Testing: ASTM A420 WPL6 fittings undergo impact testing at a specified temperature (typically -45°C) to ensure they possess the necessary toughness and resistance to brittle fracture under low-temperature conditions.
Weldability: ASTM A420 WPL6 fittings are weldable using common welding methods and techniques, enabling them to be installed and integrated into piping systems effectively.

Grades of ASTM A420 Butt Weld End Cap:
ASTM A420 is indeed the standard specification for pipe fittings made of carbon steel and alloy steel designed for low-temperature services. Among the various grades specified under ASTM A420, WPL6 is the most commonly used material grade. In addition to Grade WPL6, the standard also includes other grades such as WPL9, WPL3, and WPL8, each with different impact test temperatures corresponding to specific low-temperature service requirements:
These different grades with varying impact test temperatures allow for the selection of the most suitable material based on the specific low-temperature conditions in which the pipe fittings will be operating. It is essential to choose the appropriate grade to ensure that the fittings can withstand the required service conditions and maintain their integrity and performance at low temperatures.
