An explosion-proof pipe joint is a specialized connecting device designed for hazardous environments. Its primary function is to ensure that the connection points of pipeline systems in flammable, explosive, or corrosive environments do not leak or cause explosions. These joints are made of high-quality carbon steel or stainless steel, offering high strength, corrosion resistance, and high-temperature resistance, making them suitable for various complex working conditions.
Materials and Manufacturing Process
Our explosion-proof pipe joints are manufactured using high-quality carbon steel or stainless steel, which provide excellent mechanical properties and effectively resist corrosion and high temperatures. The thread specifications can be customized according to user requirements, including NPT threads, imperial and metric non-standard threads. Additionally, explosion-proof pipe joints can be designed with variable diameters to accommodate different pipe sizes. The joints undergo precision machining, ensuring clear and burr-free screw teeth, which makes on-site installation more compact and enhances explosion-proof performance. The surface is treated with high-temperature galvanization, further improving its anti-corrosion, explosion-proof, and high-temperature resistance properties.
Structural Forms and Compliance Standards
Our explosion-proof pipe joints come in various structural forms, such as double-ended A-type internal threads, one end with B-type internal threads and the other with external threads, and double-ended C-type external threads. These diverse structural forms can meet various complex pipeline connection requirements. The design and manufacturing of explosion-proof pipe joints strictly adhere to multiple international and domestic standards, including GB 3836.1, GB 3836.2, GB 3836.3, GB 12476.1, GB 12476.5, IEC 60079-0, and IEC 0079-1. Their explosion-proof certification is marked as [Ex d IIC Gb/Ex e lC Gb/Ex tD A21 IPB6], indicating their suitability for various explosive gas environments.
Application Fields
Explosion-proof pipe joints are widely used in various hazardous environments, including but not limited to the following areas:
Gas Stations, Oil Extraction, Refining, and Chemical Industries: In these industries, the handling of flammable and explosive gases and liquids is common. Explosion-proof pipe joints effectively prevent leaks and explosions, ensuring production safety.
Offshore Oil Platforms and Oil Tankers: The corrosive and explosive gases in marine environments demand high-performance equipment. Corrosion-resistant explosion-proof pipe joints have excellent explosion-proof performance and are ideal for these locations.
Pharmaceutical and Military Facilities: Certain chemicals in the pharmaceutical industry are highly hazardous, and military facilities may also have explosive gas environments. Explosion-proof pipe joints provide reliable safety for personnel and equipment in these settings.
IIA, IIB, and IC Explosive Gas Environments: Explosion-proof pipe joints are suitable for various explosive gas environments, meeting different hazard level requirements.
Specifications and Types
Our explosion-proof pipe joints are available in various specifications and types, including common sizes such as G1/2 threads, M20 threads, and NPT 3/4 threads. If one end is G3/4 thread and the other is G1/2 thread, it is referred to as an explosion-proof reducing joint or explosion-proof transition joint. These diverse specifications and types can meet various complex pipeline connection needs.
