Introduction
In-depth interpretation of GB/T 36018—2018 Oxygen Blowing Metal Hose Standard
1. Background and significance of standard formulation
Corrugated metal hose assemblies for oxygen lances is a key connector in the converter oxygen blowing pipeline system of the metal smelting industry, mainly used to transport oxygen and cooling water. With the advancement of industrial technology, the performance requirements for oxygen blowing metal hoses are increasing, especially in terms of high temperature resistance, high pressure resistance and long life.
This standard is managed by the National Technical Committee for Standardization of Pipeline Accessories, aiming to unify industry technical requirements, ensure product quality and safety, and improve the overall technical level. The drafting units of the standard include Aerospace Morning Light Co., Ltd., Qinhuangdao Taide Pipe Industry Technology Co., Ltd. and many other well-known companies, ensuring its scientificity and practicality.
2. Comparative analysis of standard frameworks
| Standard dimensions | GB/T 36018—2018 | Reference standards |
|---|---|---|
| Scope of application | Applicable to metal hoses connected to oxygen lances for converter oxygen blowing piping systems in the metal smelting industry, with a nominal size of DN50~DN450. | GB/T14525—2010 (General technical conditions for corrugated metal hoses) |
| Core requirements | Material, manufacturing process, appearance dimensions, performance indicators and inspection methods are mainly specified. | TB/T 47013 (Standards for Nondestructive Testing of Pressure Equipment) |
| Technological Evolution | The introduction of the inner liner winding pipe structure significantly reduced the flow resistance and noise level. | NB/T 47014 (Welding Process Qualification) |
3. Implementation Suggestions and Case Analysis
Material Selection:Austenitic stainless steel is preferred to ensure corrosion resistance and high temperature performance. In actual applications, a steel plant uses oxygen blowing metal hoses made of austenitic stainless steel, which significantly extends the service life of the equipment.
Manufacturing Process:The mesh sleeve should fit the surface of the corrugated pipe, and the machine weaving process should be preferred. For example, in the application of Aerospace Morning Light Co., Ltd., the automated braiding process has greatly improved product consistency.
Inspection method: It is recommended that users focus on the results of non-destructive testing of welds and burst tests when purchasing to ensure that product quality meets standard requirements. A case shows that hoses that fail the cleaning inspection may cause system blockage and affect production efficiency.
