The "Five-Step Method" for Selecting Elbow Pipe Fittings: A Practical Guide from Basic Understanding to Precise MatchingIn a project of a long-distance natural gas pipeline running from east to west, engineers nearly caused the entire construction period to be delayed 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 pipe fittings, these ubiquitous "joints" found in pipeline systems across various industries such as petroleum, chemical engineering, power, and municipal services, are often undervalued in terms of their importance.
