Description
The cap has a rounded closed end and a cylindrical edge formed to match the pipe outside diameter. butt weld pipe caps can be made from carbon steel, stainless steel, SA516 Gr70, SA516 Gr60, or another material named in the order. Smaller pieces are commonly pressed, while large dimensions may be spun or made through combined forming. The weld edge can be supplied square, beveled, or with machining allowance. After shaping, diameter, overall length, edge condition, and surface are checked. Pickling, passivation, blasting, coating preparation, project marking, and export packing can be arranged for the selected material.
Main Applications
Oil, gas, chemical, heating, and utility pipelines requiring permanent end closure.
Pressure-piping branches and future connection points closed before testing.
Fabricated skids where the capped line is completed before shipment.
Pipeline projects using butt weld pipe caps with matched diameter and weld preparation.
Components
- The crown forms the closed end of the fitting.
- A cylindrical edge matches the outside diameter of the pipe.
- The weld land may include a bevel and root face for the approved procedure.
- Drain holes, vents, line marks, and handling details can be included where required.
Our Factory
Pipe-cap production moves through raw-material storage, forming, finishing, inspection, finished storage, and shipping areas. Hydraulic presses rated at 315T, 500T, 1000T, and 1200T cover different cap sizes and wall conditions. Large caps can move to the cold and hot spinning lines. Automatic cutting, CNC grinding, beveling, shaping, and welding equipment support edge preparation and secondary work. Dimensional tools, material analyzers, pressure-testing equipment, and non-destructive testing instruments are available for the agreed inspection plan.
Frequently Asked Questions (FAQ)
Q: Can the bevel be matched to the pipe wall?
A: Yes. Pipe size, wall thickness, root face, bevel angle, and welding procedure should be supplied.
Q: Can caps be marked by line or spool number?
A: Yes. Project marks can be applied before packing.
Q: What is needed to order butt weld pipe caps?
A: Provide outside diameter, wall thickness, material, edge detail, quantity, surface condition, and inspection requirements.
