S32760 Introduction
Stainless steel grade F55 has excellent corrosion resistance to a wide range of areas, especially resistance to pitting andcrevice corrosion in seawater and other chloride containing environments, with critical pitting temperature that is more than 50°C(122°F). This material is known to also have high strength and extended lifecycle. It is 10% lighter than grade 316 steel, ideal for sub-zero service, and more cost effective than nickel alloys. Stainless steel grade F55 can be easily machined and welded. The following datasheet provides an overview of stainless steel grade F55.
Threaded OletIntroduction
A threaded olet is a type of branch connection accessory used in piping systems. Its core function is to allow a branch pipe to be routed through a threaded connection after a hole is drilled in the main pipe, achieving a secure connection between the main pipe and the branch pipe.Key information and features are as follows: - Core Function: Eliminates the need for complex welding or cutting of the main pipe; it quickly establishes a branch pipe passage through threaded engagement, commonly used in piping scenarios requiring convenient branching or future modifications. - Applicable Scenarios: Widely used in low- to medium-pressure piping systems in industries such as petroleum, chemical, water supply and drainage, and gas, especially suitable for transporting non-corrosive media such as water, gas, and oil. - Structural Features: Typically includes a base (some with a sealing structure) that fits snugly against the main pipe and a branch pipe interface with internal/external threads. During installation, a hole must first be drilled in the corresponding location on the main pipe, then the main pipe is fixed and the branch pipe is connected to ensure a leak-proof seal.

Processing
Raw Material Selection & Inspection:
Choose metal materials (e.g., carbon steel, stainless steel like 304/316) that meet industry standards (e.g., ANSI, DIN). Conduct dimensional checks, chemical composition analysis, and mechanical property tests (tensile strength, hardness) to ensure material qualification. Cutting & Blanking:
Use CNC cutting machines or band saws to cut the raw material (metal bars/pipes) into blanks of specified length and diameter, ensuring minimal material waste and consistent blank size. Hot Forging/ Cold Forming:- Hot Forging: Heat the blanks to a high temperature (above the material's recrystallization temperature) and use forging presses to shape them into the basic structure of the branch outlet (including the base and branch interface), enhancing material density and mechanical strength. Cold Forming:
For thin-walled or low-carbon steel blanks, use cold extrusion or stamping processes to form the shape at room temperature, maintaining precise dimensions and a smooth surface. Machining (CNC Turning & Milling) :
Use CNC lathes and milling machines to precision-machine the forged/formed blanks. Key steps include turning the outer surface of the base, milling the sealing groove (if required), and drilling/tapping the internal/external threads of the branch interface to meet thread accuracy standards (e.g., NPT, BSP). Heat Treatment:
Perform heat treatment processes (e.g., quenching and tempering for carbon steel, solution annealing for stainless steel) to adjust the material's hardness, toughness, and internal stress, ensuring the branch outlet can withstand operating pressures and avoid cracking. Surface Treatment:For corrosion resistance, apply surface treatments such as galvanizing (hot-dip galvanizing, electro-galvanizing), chrome plating, or powder coating.
For stainless steel products, conduct passivation treatment to form a protective oxide film on the surface, enhancing rust resistance. Quality Inspection:- Conduct dimensional inspection using calipers, micrometers, and thread gauges to verify that all dimensions (outer diameter, thread size, base thickness) meet design drawings. - Perform pressure testing (hydrostatic testing or pneumatic testing) to check the sealing performance of the branch outlet, ensuring no leakage under specified pressure. - Carry out visual inspection to check for surface defects (scratches, cracks, burrs) and confirm the surface treatment quality. Packaging & Storage:
Pack qualified threaded branch outlets in cartons or wooden cases with anti-rust paper or foam padding to prevent damage during transportation. Store them in a dry, well-ventilated warehouse to avoid moisture-induced corrosion.
