What is ASME B16.11 Cap
ASME B16. 11 is the standard for the forged steel fittings, including socket weld and threaded type. ASME B16.11 cap material including carbon steel, alloy steel and stainless steel. Also described as Class 2000, 3000, 6000 threaded end fittings and Class 3000, 6000, and 9000 for socket weld end fittings.
Threaded Pipe Cap is a pipe fitting with female threads on the inside of a sealed off cap end. It differs from a Threaded Plug in that it has a internal threads that screw over the pipe threads it caps.
Used in many industries, thread caps serve as protection for various industrial components. They vary in types and shapes; there are, for example, both male and female caps, as well as closures, caps or undercaps.
Specification For Stainless Steel Thread Cap
| Size | 1/8″ - 4″ /DN6-DN100 |
| Class | 3000 LBS, 6000 LBS, |
| Type | Socket weld（SW）& Threaded (THD) – NPT/PT/BSPP/BSPT/PF |
| Form | Threaded Cap, Threaded End Cap |
| Standard | ASME B16.11, BS3799, EN 10241 |
| Material | ASTM A105/A182 F304/304L/304H, 316/316L, 1.4404, 1.4437. |
ASME B16.11 Standard for Threaded Cap
ASME B16.11 threaded cap fitting is screwed to the end of pipeline, it has same function as plugs.
ASME B16. 11 is the standard for the forged steel fittings, including socket weld and threaded type. Material including carbon steel, alloy steel and stainless steel. Also described as Class 2000, 3000, 6000 threaded end fittings and Class 3000, 6000, and 9000 for socket weld end fittings.
The specification code for the fitting is the nominal diameter of thread or socket weld connection. NPS, followed by a dimensionless number, is the designation for nominal fitting size. NPS is related to the reference nominal diameter, DN, used in international standard.
NPS 1/8 ~ 4 inch corresponding to DN 6 ~100
Marking
The Specific marks should include (but are not limited to) the following:
a. Manufacturer’s Name or Trademark
Materials shall be in accordance with applicable ASME pipe fittings A234, A403, A420 or B366, or other applicable ASME forgings specifications A105, A182, A350, B160, B164 or ASME/ANSI B16.34 Table 1 (see section 5.1).
b. Material Identification.
c. Product Conformance.
The fittings in Section 1.1.1 shall be marked in accordance with the ASME Pipe Fitting Specification (eg "WP_") or the symbol "B16" to indicate compliance with this standard.
Replaceable fittings marked with ASME forging marks (A105, A182, A350, etc.) in Section 1.1.2 shall not be marked B16.
Replaceable fittings marked with ASME fittings (A234, A403, A420, and B366) in Section 1.1.2 shall be marked with the serial number of the ASTM specification applicable to special or non-standard fittings.
d. Class Designation
According to the applicable situation, it can be divided into 2000, 3000, 6000 or 9000. Alternatives the designation 2M, 3M, 6M or 9M may also be used depending on the application, where M is 1000.

Advantages For ASME B16.11 Cap
Corrosion resistance, wear resistance and high hardness.
The structure is tight, intact and the pores are small.
It has strong separation from the base metal and good adhesion.
It is evenly distributed and has a certain thickness.
