Product Description
Alloy 20 Introduction
Alloy 20 is an austenitic stainless steel containing less than 50% iron and is used in applications involving sulfuric acid. Its
corrosion resistance also finds other applications in the chemical, petrochemical, power generation, and plastics industries.Alloy 20 exhibits superior resistance to pitting and chloride ion corrosion compared to 304 stainless steel and is comparable to316L stainless steel. Its copper content protects it from sulfuric acid. Alloy 20 is typically selected to address the potentialstress corrosion cracking issues of 316L stainless steel.

Alloy 20 Butt Welding Fitting Lap Joint Stub End Introduction
Lap joint stub end is a type of steel butt weld fitting, generally used together with lap joint flanges. According to the length
of the straight end, lap‑joint stub ends are divided into long‑pattern stub ends and short pattern stub ends. Its manufacturing standards are mainly ANSI/ASME B16.9 and MSS SP‑43. Materials include carbon steel, stainless steel, alloy steel and so on. The common American standard for stainless‑steel stub ends is ASTM A403. Lap joint stub ends are widely used in piping systems of petroleum, chemical, natural gas and other industries.
The flanged surface of the lap joint stub end can act as a gasket and provide sealing performance. The adoption of lap joint stub ends facilitates disassembly of specific sections of pipelines for cleaning, inspection and quick replacement. Lap joint stub ends cover a wide size range from 1/2" to 24" (DN15‑DN600). They feature excellent tensile strength, corrosion resistance and wear resistance.

Butt Welding Fitting Lap Joint Stub End Processing
1. Raw Material Selection & Inspection:
Select qualified raw materials including carbon steel, stainless steel, alloy steel, duplex steel, low-temperature steel, line pipe steel and nickel-base alloy. Verify material certificates, chemical composition and mechanical properties to comply with ASME, ASTM and relevant industry standards.
2. Blanking & Marking:
Perform precise marking and cutting on seamless steel pipes, steel plates or steel billets according to product specifications (DN15-DN600, SCH standard wall thickness) to obtain standard pipe or plate blanks with accurate size and uniform thickness.
3. Cold / Hot Forming:
3. Cold / Hot Forming:
Adopt stamping, bending, extrusion, mould pressing and other cold or hot working processes. Complete integral forming for pipe-made and plate-made lap joint stub ends to form standard straight end and lap flanged structure.
4. Forging & Shaping:
4. Forging & Shaping:
Process the formed blanks through forging press to optimize overall structure, ensure compact texture and uniform wall thickness, and avoid forming defects such as wrinkles and deformation.
5. Welding Process (for large size):
Apply professional welding procedures for large-diameter stub ends to ensure firm weld joint, smooth weld surface and no welding defects.
6. Heat Treatment:
Conduct solution heat treatment for stainless steel and alloy steel materials, and stress relief treatment for formed and welded workpieces to eliminate internal stress, improve corrosion resistance and structural stability.
9. Non-Destructive Testing:
Carry out standard NDT inspection to detect cracks, inclusions, pores and other internal and surface defects, ensuring no quality hazards.
10. Finishing & Warehousing:
Remove surface burrs, clean oil stains and rust, mark product specifications, material grade and standard information, and classify and warehouse qualified products.
