I. Overview of hydraulic hoses
Hydraulic hose is a pipeline equipment used for conveying high-pressure liquids, which has good performance in pressure resistance, corrosion resistance, wear resistance, and other aspects. It is widely used in industries, construction, transportation and other fields. This article will introduce the production process of hydraulic hoses.
II Domestic standards
GB/T 3683-2001 “Rubber and plastic hoses and hose assemblies – Fabric reinforced for hydraulic purposes”: This standard specifies the classification, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of fabric reinforced rubber and plastic hoses and hose assemblies.
GB/T 7939-2008 Terminology for Rubber and Plastic Hoses and hose assemblies: This standard specifies the relevant terms and definitions for rubber and plastic hoses and hose assemblies.
III. International standards
ISO 14362-1:2014 “Rubber and plastic hoses – Part 1: General requirements”: This standard specifies the general requirements for rubber and plastic hoses, including materials, structure, dimensions, marking, testing methods, and other aspects.
ISO 14362-2:2014 “Rubber and plastic hoses – Part 2: Steel wire braided reinforced hoses”: This standard specifies the requirements, test methods, inspection rules, and other aspects of steel wire braided reinforced hoses.
IV. Detailed explanation of hydraulic hose production process
Preparation of raw materials
The main raw materials for hydraulic hoses include rubber, fiber reinforced materials (such as steel wire), fillers, softeners, etc. Strict screening and testing of these raw materials are required before production to ensure their quality meets relevant standard requirements.
Pipe making process
The manufacturing process of hydraulic hoses usually consists of the following steps:
(1) Extrusion molding: Mix rubber and other raw materials in a certain proportion and extrude them into tubular shapes through an extruder.
(2) Reinforcement treatment: The extruded tubular material is reinforced by a reinforcement machine to provide sufficient strength and pressure resistance.
(3) Sulfurization treatment: The reinforced tubular material is subjected to vulcanization treatment to achieve good corrosion resistance and wear resistance.
(4) Cooling and shaping: Cooling and shaping the vulcanized tubular material to achieve stable size and shape.
Post treatment process
The post-treatment process of hydraulic hoses usually includes the following aspects:
(1) Surface treatment: To treat the surface of hydraulic hoses to improve their corrosion resistance and appearance quality. Common surface treatment methods include spraying, electroplating, etc.
(2) Cutting processing: According to actual needs, the hydraulic hose is cut and processed to produce products of different lengths and diameters.
(3) Inspection and testing: Conduct various performance tests on hydraulic hoses to ensure they meet relevant standard requirements. Common testing items include pressure testing, leak testing, etc.
V. Conclusion
The production process of hydraulic hose directly affects its performance and usage effect, so it is necessary to strictly follow the relevant standard requirements for production and quality control. When consumers choose hydraulic hoses, they also need to understand relevant production process information in order to better choose and use products. I hope this article can provide a detailed introduction to the production process of hydraulic hoses and provide some reference value.
