Macomb Group 1000104sseasi Short Stub End 10 in 304SS Sch 10

Product Description

The MACOMB GROUP 1000104sseasi is a Type A Short Stub End fitting manufactured from 304 stainless steel to ASTM A403 and ASME SA403/SA403M material standards. Designed for buttweld installation, this stub end features a 10-3/4 inch outside diameter, a 12-3/4 inch lap diameter, and a 1/2 inch fillet radius. The fitting is rated for Schedule 10 pipe wall thickness and has an overall length of 5 inches. It meets MSS-SP-43 industry standards, making it a code-compliant choice for stainless steel piping systems in industrial and process piping applications. Licensed pipefitters and pipe welders are the primary installers of this component.

This stub end is intended for use in 10-inch nominal diameter piping systems where a lapped joint flange connection is required. The Type A short pattern is commonly used when space constraints limit the use of a long stub end. Typical applications include process piping, chemical distribution, food and beverage facilities, and other systems where corrosion resistance and hygienic material properties of 304 stainless steel are required. The buttweld end prep allows for full-penetration socket or butt weld integration into the pipeline at the appropriate schedule.

Key Features

• Type A short pattern stub end for lapped joint flange assemblies
• 304 stainless steel construction meeting ASTM A403 and ASME SA403/SA403M standards
• 12-3/4 inch lap diameter provides full seating surface for a matching lap joint flange
• 1/2 inch fillet radius for smooth flow transition and reduced turbulence at the lap face
• Schedule 10 wall thickness for lightweight stainless piping systems
• Compliant with MSS-SP-43 industry standard for stainless steel butt-welding fittings

Compatibility

Designed for use with 10-inch nominal Schedule 10 stainless steel pipe in buttweld lapped joint configurations conforming to MSS-SP-43 requirements.

Installation Notes

Installation of this stub end should be performed by a qualified pipefitter or certified pipe welder in accordance with applicable welding procedures and piping codes, including ASME B31.3 for process piping. Depressurize and drain the system completely before performing any welding or fitting work. The stub end is butt-welded onto the pipe first, and the lap joint flange is slipped over the pipe before welding. Do not apply heat directly to the lap face, as distortion can compromise the sealing surface.
