Pipe Fittings CAPS, B.W. ENDS, ASTM A-420, GR.WPL6, SMLS AS PER ANSI/ASME B 16.9.IN THE FOLLOWING SIZES:6" SCH. XS

Pipe caps are also known as heads, plugs, caps, pipe caps, and bulkheads, which are welded on the pipe end or installed on the external thread of the pipe end to cover the pipe fittings. Used to close the pipeline, the function is the same as the pipe plug.
Types of
The form of the blind plate is similar, except that the blind plate can be disassembled and blocked, while the welded pipe cap cannot be disassembled. The cap includes a convex cap, a cone shell, a variable diameter section, a flat cap and a shrinking port design.
Convex tube caps include: hemispherical tube caps, oval tube caps, dish-shaped tube caps and spherical caps. From the perspective of stress, the hemispherical cap is gradually not good for the convex cap, but from the difficulty of manufacturing, it is gradually easier to manufacture.

1. Basic information of ASTM A420 WPL6 low temperature steel:
Grade: ASTM A420 WPL6
Product name: Low-temperature forged carbon steel for American standard seamless welded structural pipe fittings
Executive standard: ASME SA-420/SA-420M ASTM A-420/A-420M
Delivery status: controlled rolling/normalizing 173+4499+0288. (The specific delivery status is indicated in the contract.)

2. ASTM A420 WPL6 low temperature steel classification:
1. A420WPL6 low temperature steel is divided into carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, A420WPL6 low temperature steel heat treatment, leaching, ppc, etc.
2. A420WPL6 low temperature steel can be divided into pushing, pressing, forging, casting, etc. according to the manufacturing method.
3. A420WPL6 low temperature steel can be divided into national standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc. according to manufacturing specifications.
4. A420WPL6 low temperature steel is classified according to its radius of curvature: it can be divided into long radius elbow and short radius elbow. Long radius elbow refers to the outside diameter of the tube whose radius of curvature is equal to 1.5 times, that is, R=1.5D short radius elbow refers to its radius of curvature equal to the outside diameter of the tube, that is, R=1.0DD is the diameter of the elbow, and R is the radius of curvature) .
3. ASTM A420 WPL6 low temperature steel chemical composition

1. According to the agreement, the limit value of Nb content can be increased to 0.06% for finished product analysis.
2. For fittings made of steel plates, the maximum manganese content can reach 0.98%.
