Product Description
Alloy 718 Introduction
Alloy 718/2.4668 is a nickel-chromium-iron alloy with niobium and molybdenum and low contained aluminum and tnum. Excellent mechanical properties in lower temperatures. Excellent corrosion resistance at high and low temperatures Inconel 718 is a nickel-based super alloy that is well suited for applications requiring high strength in temperature ranges from cryogenic up to 1400°F. Inconel 718 also exhibits excellent tensile and impact strength.
Concentric/Eccentric Swaged Nipple Introduction
A swage nipple is a forged pipe fitting used to connect pipes of two different diameters within small-bore piping systems.
1.Overview and Purpose: Facilitates a smooth transition in pipe diameter over a short distance.
2.Manufacturing Process: Produced from forged steel bars or billets, rather than fabricated from metal plate.
3.Standards: Typically manufactured in accordance with the MSS SP-95 standard.
4.Applications: Commonly used in high-pressure oil, gas, and petrochemical facilities for drain lines, vent lines, and instrument piping.
5.Concentric vs. Eccentric Swage Nipples: Concentric swage nipples feature a symmetrical design with aligned centerlines; primarily used in vertical piping, they help maintain stable, symmetrical flow and minimize turbulence. Eccentric swage nipples feature an asymmetrical design with offset centerlines, maintaining a flat top or bottom alignment; primarily used in horizontal piping, this alignment prevents liquid accumulation, gas pockets, or fluid stagnation.

1.Raw Material Cutting & Pre-inspection
Cut seamless pipe to required blank length. Check pipe OD, wall thickness and surface, reject tubes with cracks or pits.

2.End Preparation & Squaring
Face and square both ends, remove burrs, ensure end face perpendicular to pipe axis for subsequent swaging.
3.Hot / Cold Swaging Forming
Perform swaging process to reduce one end diameter. Make concentric for concentric nipple; offset centerline strictly for
eccentric swaged nipple to meet offset dimension.
4.Machining & Chamfering
Machine the formed end, add chamfer. Control transition smoothness, avoid sharp step and metal folding.
5.Cleaning & Surface Treatment
Remove lubricant, metal chips. Carry out galvanizing, black oxide or painting as customer requirement for anti-corrosion.
6.Final Inspection & Export Packaging
Check dimension, offset value, wall thickness and surface defects. Mark specs, then pack qualified goods with export package.
