How much do you know about the details of industrial stainless steel pipe fittings

First, how to calculate the length of stainless steel pipe fittings.
1. 1.5 times the center height of the elbow = nominal diameter * 1.524. Essentially, it's nominal diameter * multiple. Round the result to the nearest integer. For example, a 219 elbow has a nominal diameter of 200, so the center height is 200 * 1.524 = 304.8, rounded to 305. Similarly, a 114 elbow has a nominal diameter of 100, so the center height is 100 * 1.524 = 152.4, rounded to 152. (This calculation method applies to elbows with a curvature radius of DN100 and above, providing a convenient and quick calculation.)
2. Indentation Height = Center Height + Bending Radius: For example, the insertion height of a bend with a diameter of 1.5 times 219 is 305 + 219/2 = 305 + 109.5 = 414.5.
3. Outer Arc Length = (Center Height + Radius) * 3.14 * 2 / 360 * Degrees: This is equivalent to (Indentation Height) * 3.14 * 2 / 360 * Degrees. Therefore, the outer arc length of a 90-degree bend can be calculated as: Insertion Height * 3.14 / 2.
4. Inner Arc Length = (Center Height - Radius) * 3.14 * 2 / 360 * Degree
5. Elbow cutting length = Elbow center height * 3.14 / 2 * Elbow outer diameter / Pipe diameter + (Pipe wall thickness * 3) + Machining allowance. For example, if using a 180*8 pipe to cut a 273 elbow, the cutting length can be calculated using the above formula: Cutting length = 381 * 1.57 * 273 / 180 + 24 = 931.22 mm + Machining allowance.

Second, what are the advantages of stainless steel pipe fittings?
① Material performance advantages: Thin-walled stainless steel water pipes, as the name suggests, use stainless steel. Stainless steel has high strength, three times that of copper pipes and 8-10 times that of PPR pipes, and can withstand the impact of high-speed water flow of 30 meters per second. At the same time, its low thermal conductivity and good insulation performance make it particularly suitable for hot water pipes. Furthermore, stainless steel has no exudates, achieving zero pollution, making it more hygienic and healthier for household water pipes. Furthermore, thin-walled stainless steel water pipes have an exceptionally long service life, sometimes even matching that of the building itself.
② Environmental Advantages: Nowadays, all industries prioritize environmental protection, and the water pipe industry is no exception. Many well-known water pipe materials produce persistent high-molecular-weight waste or harmful substances during use. Thin-walled stainless steel water pipes, however, are recyclable after use without generating any waste or environmental pollution.
③ Connection Technology Advantages: Thin-walled stainless steel water pipes utilize various connection methods, such as press-fit and snap-fit connections, extending product lifespan and simplifying maintenance. Especially when used with appropriate fittings and sealing rings, they can be reused multiple times, ensuring reliable and safe connections. These connection methods eliminate the risk of tearing due to thermal expansion and contraction in threaded, welded, and glued connections.
④ High Cost-Effectiveness: Many consumers believe that while thin-walled stainless steel water pipes offer many advantages, their price is relatively high. From a long-term perspective, thin-walled stainless steel water pipes require only a one-time investment. If they have a long service life and require no maintenance or repairs, and their leak-free operation reduces the risk of household leaks, they are very cost-effective in the long run.
⑤ Aesthetic Advantage: Especially for home plumbing, a beautiful and simple appearance has become a goal for many families. Thin-walled stainless steel water pipes, with their shiny surface, are very suitable for exposed installation in kitchens. When renovating plumbing in older homes, there's no need to demolish walls and remove old pipes; thin-walled stainless steel water pipes can be installed directly on the wall, not only delivering water but also preserving the home's décor.
⑥ Potential Advantage: In recent years, with the widespread adoption and application of thin-walled stainless steel water pipes worldwide, and with experts continuously affirming their practical applications and advantages, their application potential is enormous. Furthermore, with increasing awareness of health and environmental protection, thin-walled stainless steel water pipes will become the preferred choice for more and more projects and homes.
