4 بوصة أنابيب الفولاذ المقاوم للصدأ
4 Inch Stainless Steel Pipe offers a balance of flow capacity, مقاومة التآكل, and structural strength, with standardized nominal diameter and multiple schedule options.
By selecting the correct schedule (SCH) and wall thickness, this pipe can meet both low-pressure and high-pressure system requirements in industrial and commercial applications.
- وصف
4 Inch Stainless Steel Pipe is a widely used nominal pipe size in صناعي, كيميائية, water, and HVAC systems.
In inch-based (imperial) systems, its nominal size is 4 بوصة, with actual outside diameter and wall thickness varying by schedule (SCH).
This pipe is commonly available in SCH 10, SCH 40, SCH 80, and other schedules to suit different pressure, الهيكلية, and fluid transport requirements.
4 Inch Stainless Steel Pipe Dimensions
| Schedule (SCH) | Outside Diameter (في) | سمك الجدار (في) | Inside Diameter (في) | Typical Length (قدم) |
|---|---|---|---|---|
| SCH 10 | 4.5 | 0.120 | 4.26 | 20 قدم |
| SCH 20 | 4.5 | 0.188 | 4.12 | 20 قدم |
| SCH 40 | 4.5 | 0.237 | 4.03 | 20 قدم |
| SCH 80 | 4.5 | 0.337 | 3.83 | 20 قدم |
| SCH 160 | 4.5 | 0.500 | 3.50 | 20 قدم |
ملحوظة: The outside diameter (ل) of all 4-inch pipes is 4.5 بوصة, per NPS standards. Wall thickness varies according to the schedule number, affecting the inner diameter and pressure rating.
