Buttweld fittings are available in various grades, primarily categorized by material type (carbon steel, stainless steel, alloy steel, etc.) and specific material standards (like ASTM A234 for carbon steel or ASTM A403 for stainless steel). Within these categories, different grades (e.g., WPB, WP304/304L, WP316/316L) are specified, each with its own chemical composition and mechanical properties.
Here's a breakdown of common buttweld fitting grades:
1. Carbon Steel:
ASTM A234 WPB: This is the most common grade for carbon steel buttweld fittings, known for its weldability and suitability for general-purpose applications.
ASTM A234 WPC: Another carbon steel grade, often used in higher-pressure applications.
MSS-SP-75 WPHY: High-yield carbon steel grades (e.g., WPHY 42, 46, 52, 56, 60, 65, 70) used in high-pressure pipelines.
ASTM A420 WPL3/WPL6: Low-temperature carbon steel grades.
2. Stainless Steel:
ASTM A403 WP304/304L/304H: Austenitic stainless steel grades, with 304L being a low-carbon version for enhanced weldability.
ASTM A403 WP316/316L/316H: Austenitic stainless steel grades, with 316L being a low-carbon version, and 316Ti offering enhanced high-temperature strength.
Other Grades: 317/317L, 321, 310, 347, 904L, 2205 Duplex.
3. Alloy Steel:
ASTM A234 WP1/WP5/WP9/WP11/WP22/WP91: These grades are used in high-temperature and high-pressure applications.
4. Other Materials:
Nickel Alloys: Monel, Nickel, Inconel.
Copper Nickel: CuNi10Fe1Mn, CuNi30Mn1Fe.
Aluminum, Titanium, etc.: Various other materials are also used for specific applications.
ASME B16.9 is a common standard for buttweld fittings, specifying dimensions and tolerances.

The threaded joint refers to the pipe connector with thread, is the most common kind of pipe fittings in industry and life, the threaded joint makes the connection of the pipe more simple, disassembly and replacement is also easier, greatly saving the cost of pipe connection.
Industrial thread joint is generally made of metal, high pressure resistance, materials are carbon steel, stainless steel, alloy steel, brass, etc.
Black pipe nipple is made of carbon steel pipe, and face is black, thread standard is ASTM
A pipe closed nipple is a short, threaded pipe fitting that has closed ends. It is typically used to connect two pipes or to tee off a pipe. Pipe closed nipples are available in a variety of materials, including steel, stainless steel, brass, and plastic. They are also available in a variety of sizes, with the most common sizes being 1/4 inch, 3/8 inch, and 1/2 inch.
Here is a technical specification of a pipe closed nipple:
1. Size: 1/8 Inch to 4 Inch Customized Up to 12â??
2. Material: Carbon steel, Alloy Steel, Stainless steel, Duplex
3. Thread: NPT, BSP, BSPT
When choosing a pipe closed nipple, it is important to consider the material, size, thread type, and length. It is also important to make sure that the nipple is compatible with the other components in the system.
Here are some additional things to keep in mind when using pipe closed nipples:
A. Pipe closed nipples should be tightened to the correct torque specification to prevent leaks.
B. Pipe closed nipples should not be used in applications where they will be exposed to high temperatures or corrosive chemicals.
C. Pipe closed nipples should be inspected regularly for leaks and damage.
