In modern industrial piping, OLET (nozzle or branch connection) is an indispensable key component. It is designed and applied to enable efficient and safe connections between main and branch pipelines and to address complex fluid transfer path requirements. This article will detail the main uses of OLET and its widespread use in various industries.
1. The basic concept and types of OLET
OLET, the full name of "outlets" in English, that is, nozzle or branch pipe connection, is a fitting installed on the main pipe by welding to extend the function of the pipe and provide additional outlets or connection points. According to the different structural forms and installation methods, OLET mainly has the following types:
Welding neck olet: It has a long neck at the end, similar to a butt welding flange, and is connected to the main pipe by welding, which can effectively disperse stress and ensure good sealing performance.
Socket welding oletThis type of OLET is equipped with a socket inside, which can be directly inserted into the main pipe for welding, and is suitable for small diameter high-pressure piping systems.
Threaded olet: With external thread, it can be screwed directly into the main pipe with internal thread, which is convenient and quick to install, and is commonly used in piping systems with low-pressure non-corrosive media.
Other special types of olets: Such as latrolet, elbow-olet, reducer-olet, sweepolet, etc., which correspond to the branch connection requirements of various complex shapes and functions such as elbow type, variable diameter type, sweep type, etc.
Second, the main purpose of OLET
Branch pipe connectionsAs a transitional connection between the main pipeline and the branch pipeline, the OLET can flexibly add inlets and exits to meet the needs of multiple transportation, distribution or collection of fluids without changing the overall structure of the main pipeline.
Device interfaceIn the oil and gas, chemical, electric power, nuclear energy and other industries, OLET is often used to connect the main pipeline to various pumps, valves, reactors, heat exchangers and other equipment to ensure the integrity and reliability of the system.
Easy maintenance and repairDue to the OLET, the main pipe system is more convenient when it is necessary to add or replace branches, which greatly reduces downtime and maintenance costs.
Stress level adaptabilityDifferent types of OLET can be applied to the piping system of different pressure levels, which fully guarantees the safe operation of the system.
3. Application fields of OLET
Oil and gas industry: In oil well exploitation, oil pipelines, refineries and other links, OLET has played an important role in building a complex and efficient oil and gas transmission network.
Chemical industryFrom raw material handling and reaction process to product storage and transportation, all kinds of OLET are important components of connecting equipment and building piping systems.
Electricity production: Various energy fields, including thermal power generation, hydroelectric power generation, and nuclear power generation, need to use OLET to complete the precise control and transmission of fluids such as steam and cooling water.
Offshore Engineering & ShipbuildingOLET is also an indispensable component in ship power systems, cabin water supply and drainage systems, and offshore platform facilities to cope with harsh environmental conditions and safety requirements.
In summary, OLET plays a vital role in industrial piping systems due to its diverse structural design and excellent mechanical properties, providing a flexible, reliable and cost-effective solution for fluid transfer in modern industry. With the advancement of technology and the change of market demand, the design and manufacturing process of OLET is constantly optimized and upgraded, and continues to serve the pipeline construction and maintenance work of various industries around the world.
