Introduction
In modern piping and fluid systems, threaded fittings serve as indispensable components for creating secure, leak-proof connections without welding. These fittings are prized for their versatility, ease of installation, and adaptability across industries. At DingYang, we combine cutting-edge manufacturing expertise with stringent quality control to deliver threaded fittings that excel in performance, durability, and safety. Whether for industrial pipelines, hydraulic systems, or residential plumbing, our solutions are engineered to meet the highest global standards.
What Are Threaded Fittings?
Threaded fittings are connectors with standardized internal (female) or external (male) threads, designed to screw together pipes, valves, or equipment. Unlike welded joints, threaded connections allow for quick assembly, disassembly, and maintenance, making them ideal for applications where flexibility and safety are paramount.
Key Advantages of Threaded Fittings:
Ease of Installation: No specialized welding equipment or skills required, reducing labor costs and downtime.
Leak Resistance: Precision-machined threads ensure tight seals, even under moderate pressure.
Versatility: Compatible with a wide range of materials, including carbon steel, stainless steel, brass, and plastics.
Adaptability: Suitable for temporary setups, repairs, or systems requiring frequent modifications.
Safety: Ideal for hazardous environments (e.g., oil and gas) where welding poses risks.
Types of Threaded Fittings by DingYang
We offer an extensive portfolio of threaded fittings tailored to diverse industrial needs:
1. Threaded Elbows
90° and 45° Elbows: Redirect flow efficiently in plumbing, HVAC, and chemical processing systems.
Materials: Available in stainless steel (ASTM A182) for corrosion resistance or carbon steel (ASTM A105) for high strength.
2. Threaded Tees
Equal/Unequal Tees: Branch pipelines into three directions for water supply, gas distribution, or industrial cooling systems.
3. Threaded Couplings
Full Couplings: Connect two pipes of the same diameter seamlessly.
Half Couplings: Attach to pipes or equipment for easy integration.
4. Threaded Unions
Three-Piece Unions: Enable quick disassembly for maintenance without disturbing the entire pipeline.
5. Threaded Caps and Plugs
Hex Head Caps: Seal pipe ends during maintenance or pressure testing.
Square Head Plugs: Provide secure closures for gas or liquid systems.
6. Threaded Bushings and Reducers
Hex Bushings: Adapt between different pipe sizes in confined spaces.
Concentric/Eccentric Reducers: Maintain flow efficiency while transitioning pipe diameters.
Materials and Standards
At DingYang, material selection is critical to ensuring longevity and performance:
Carbon Steel (ASTM A105): High tensile strength for general industrial use.
Stainless Steel (ASTM A182 F304/F316): Resists corrosion in chemical, marine, and food-grade applications.
Alloy Steel (ASTM A182 F11/F22): Withstands high-temperature and high-pressure conditions in power plants.
Brass and Bronze: Ideal for potable water systems and low-pressure gas lines.
Compliance with Global Thread Standards:
NPT (National Pipe Tapered): ANSI/ASME B1.20.1 (common in North America).
BSP (British Standard Pipe): Parallel (BSPP) or tapered (BSPT) threads (widely used in Europe and Asia).
Metric Threads: DIN/ISO standards for international compatibility.
