Description

Socket welding pipe cap is a high-pressure pipe connection fitting, also known as forged steel pipe cap, mainly used in high-pressure pipeline systems. Its main features include:

‌Nominal diameter‌: from 1/4" to 5", specifically DN20-DN200.

‌Nominal pressure‌: provides a variety of pressure levels, including PN40, 64, 100, 160, 250, 320, 1500, 2000, 2500, 3000, 6000LBS.

‌Applicable medium‌: suitable for water, steam, oil and other media.

‌Material‌: including 321, 304, 304L, 316, 316L, 15CrMo, 12Cr1MoV and other materials.

‌Connection form‌: adopt butt welding connection to ensure the firmness and reliability of the connection.

Material

The materials of socket weld pipe caps include Q235, 20#, A234WPB, st37, 304, 304L, 316, 316L, 15CrMo, 12Cr1MoV, P91, P11, 16Mn, X42, X52, X65, X70, etc.

Specifications and Dimensions

The specifications and sizes of socket weld pipe caps are mainly produced according to standards such as GB/T14383 and ASME B16.11. These standards cover a size range from DN6 to DN100, where DN represents the nominal diameter of the pipe. The wall thickness and pressure rating of socket weld pipe caps are also specified in detail, including 3000#, 6000#, 9000#, etc. These specifications are suitable for applications under different pressure and temperature conditions.

Usage Instructions

The method of using the socket weld pipe cap mainly involves socket welding it with the pipe or other pipe fittings to ensure the firmness and sealing of the connection. The following are some key steps and precautions for the use of the socket weld pipe cap:

‌1. Prepare tools and materials‌: Make sure you have the necessary welding tools, such as a welding machine, and appropriate welding materials, such as welding rods or welding wires.

2. Clean and prepare the pipe: Before welding, make sure that the surface of the pipe and the socket weld pipe cap is clean and free of oil, rust or other impurities to ensure the quality of welding.

‌3. Positioning and fixing‌: Place the socket weld pipe cap correctly on the pipe and fix it with appropriate clamps or tools to ensure that it does not move during welding.

4. ‌Welding‌: Use a welding machine or welding gun to weld the socket weld pipe cap to the pipe according to the selected welding method (such as manual arc welding, gas shielded welding, etc.). During the welding process, attention should be paid to controlling the welding speed and heat input to ensure the quality of the weld.

‌5. Check welding quality‌: After welding is completed, necessary inspections should be carried out, such as appearance inspection, non-destructive testing, etc., to ensure that the welding quality meets the requirements.

6.‌ Subsequent treatment‌: Perform appropriate post-treatment on the welding area, such as grinding, painting, etc., to protect the welding part from corrosion and damage.
