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.

Nirmaan Pipes is one of the leading manufacturers of UPVC Fitiings in Eastern India. Nirmaan UPVC Fittings are manufactured in strict accordance to the standards of ASTM-D-2467 and are joined and installed with Nirmaan UPVC pipes manufactured according to ASTM-D-1785.
Basically, an end cap will be applied, to shut down the end of a pipe. It is available for all pipe dimensions. They are used to close pipes of large diameters, and are similar to those used for constructing vessels.
Galvanized Rail End Caps For Galvanized Chain Link Fencing
Rail end caps information
Rail end caps as one of chain link parts
--Used to attach top rail to a Bullet Top terminal post cap.
--Residential Use.
--Great for making a 3 directional or odd angle toprail connection.
There are two kinds of material for rail end caps
Aluminum and press steel.
1-3/8 inch and 1-5/8 inch are the most popular.Of course if you have other size for need,that is ok.We could customized that.
1-3/8 in. aluminum rail end is essential in finishing up your chain link fencing projects. Made from a durable aluminum construction with a sleek, polished silver finish, this rail end is used in conjunction with 1-3/8 in. top rails and brace bands to secure top rails to terminal posts.
