"Five-step Method" for Elbow Fittings Selection: A Practical Guide from Basic Understanding to Precise MatchingIn a long-distance natural gas pipeline project running from east to west, engineers almost delayed the entire construction period due to a disagreement over the selection of a 90-degree elbow. Eventually, a stress analysis report based on the latest national standard GB/T 29168.2-2024 became the key to reaching a consensus. Elbow fittings, these ubiquitous "joints" in pipeline systems across industries such as oil, chemical, power, and municipal, are often underestimated in terms of their significance. An improper choice can, at the very least, increase energy consumption and shorten the system's lifespan, and at worst, lead to leaks, shutdowns, or even safety incidents. This article will systematically break down the five core selection principles of elbow pipe fittings for you, providing you with a complete decision-making framework for selection from theory to practice. 01 Qualitative Analysis: Clarify Requirements and Lay a Solid Foundation for Selection
