This SAE Aerospace Standard (AS) defines the requirements for a convoluted polytetrafluoroethylene (PTFE) lined, metallic reinforced, hose assembly suitable for use in aerospace fluid systems at temperatures between -65 °F and 400 °F for Class 1 assembly, -65 °F and 275 °F for Class 2 assembly, and at operating pressures per Table 1. The use of these hose assemblies in pneumatic storage systems is not recommended. In addition, installations in which the limits specified herein are exceeded, or in which the application is not covered specifically by this standard, shall be subject to the approval of the procuring activity.
Heat shrink polymer is a type of material used in many industries’ segments due to their ability to contract and fit snugly around objects when heat is applied. These products are commonly commercialized in tube format (e.g.: sleeves), made from polyolefin or fluoropolymers, which have the property of shrinking when heated. Nanomaterials present many applications, and their usage is a remarkable tool aiming to improve many properties of materials. Then, many improvements including increase of performance and price reduction may be achieved due to its unique properties when nanomaterials are used into heat shrink polymer sleeves. This work presents a systematic review about the state of the art on heat-shrinkable materials for the automotive industry. As a methodology, articles from the last 10 years on the subject were selected. The keywords “heat shrink” AND “nanomaterial” AND “tubes OR sleeves” were used in three different databases, being “Scopus”, “Web of Science” and “MDPI”. After

The goal of this work is to increase the accuracy and efficiency of hose cutting operations in small scale industries is by designing and building an automatic hose-cutting equipment. The device uses a computer-controlled system to autonomously cut pipes of various sizes and lengths. By means of a stepper motor-driven, rapidly spinning blade, the cutting process is accomplished. Additionally, the machine has sensors that measure the hose's length and modify the cutting position as necessary. Premium components and materials are used in the machine's construction; these are chosen for their performance and longevity. The device is able to boost cut precision and raise industry production all around from 100% to 190% efficient system thereby decreasing labor and time needed for hose cutting operations.

Whether for vascular catheters or implantable devices, medical tubing must meet tough standards for flexibility, strength, and biocompatibility. That’s why more manufacturers are turning to thermoplastic polyurethanes (TPUs) that strike the ideal balance between these key properties, making them an excellent choice for high-performance medical tubing. Unlocking the best that TPUs have to offer means optimizing the extrusion process. This article looks at why TPUs are a top pick, the common obstacles in extrusion, and the ways manufacturers can fine-tune their process to get the most out of different grades.
This SAE Standard encompasses the recommended minimum requirements for non-metallic tubing and/or combinations of metallic tubing to non-metallic tubing assemblies manufactured as liquid- and/or vapor-carrying systems designed for use in gasoline, alcohol blends with gasoline, or diesel fuel systems. This SAE Standard is intended to cover tubing assemblies for any portion of a fuel system which operates above −40 °C (−40 °F) and below 115 °C (239 °F), and up to a maximum working gage pressure of 690 kPa (100 psig). The peak intermittent temperature is 115 °C (239 °F). For long-term continuous usage, the temperature shall not exceed 90 °C (194 °F). It should be noted that temperature extremes can affect assemblies in various manners and every effort must be made to determine the operating temperature to which a specific fuel line assembly will be exposed, and design accordingly. The applicable SAE standards should be referenced when designing liquid-carrying and/or vapor-carrying
This test method provides a standardized procedure for evaluating the electrochemical resistance of automotive coolant hose and materials. Electrochemical degradation has been determined to be a major cause of EPDM coolant system hose failures. The test method consists of a procedure which induces voltage to a test specimen while it is exposed to a water/coolant solution. Method #1, referred to as a “Brabolyzer” test, is a whole hose test. Method #2, referred to as a “U” tube test, uses cured plate samples or plates prepared from tube material removed from hose (Method No. 2 is intended as a screening test only). Any test parameters other than those specified in this SAE Recommended Practice, are to be agreed to by the tester and the requester.
