The insulating Joints is a new generation developed product to resolve use problems of old insulating flange. It is the essential pressure component necessary for steel pipeline cathodic protection system, broadly applicable to steel pipeline cathodic protection systems. Our companys insulating connectors adopts a unique design based on referencing foreign latest product structure to overcome problems of inadequate rigidity, prone to leak, unable to be buried under ground, short service life, etc. The insulating connectors have realized buried parts maintenance-free function and allow a service life matching the pipelines.

Technical characteristics:
Pressure grade:PN1.0-PN40MPa
Service life:same as the service life of pipeline
Ambient temperature:-30°C-90°C
Applicable medium: oil, gas, water, chemical feed, mineral slurry

Quality requirement:
Insulating resistance value≥10MΩ @DC1000V, Maximum voltage:≥3KV
Insulating intensity: no breakdown or arc for one minute @2500V 50Hz
Hydraulic pressure testing pressure: 1.5 times of desingned pressure
Air-tight testing pressure: equivalent to designed pressure
Non-destructive testing: All the butt-connectors are 100% ray-detected according to JB4730-94; other pressure welding
seams are 100% magnetic power detected.
Groove: adopt AP15L standard

Quality requirement:
This product adopt's material satisfy below request

UL certification and FM certification is a product of technical standards, product quality requirements of the most authoritative certification, the certification bodies are located in the United States.
UL certification is a certification related to safety certification, originated in the Underwriters Laboratories. UL is the Underwriters Laboratories written (Underwrites Laboratories Inc.), it is the world's largest engaged in safety testing and identification of civil society One is an independent third party inspection agency, is a non-profit, professional training for public safety it has product testing, factory inspection; data, the preparation and distribution of standards; product safety certification and operational safety Proof and other business.
UL mark is divided into three categories, namely, column name, classification and recognition of signs, respectively, applied to different service products, is not common. All UL products must have UL listed, approved or graded logo. In our country grading signs are rare, the vast majority is listed, approved products. UL tracking test class R and large class, L class is mainly used for life safety related products, such as fire extinguishers, detectors, power equipment, Wire, etc. R products are mainly electrical equipment, such as television, fans, hair dryer, oven and so on. For products belonging to large class. The manufacturer must be affixed directly to the product on the UL order mark.
FM is the United States factory mutual protection research center (Factory Mutual). Industrial and commercial products "FM" certificates and test reports are generally recognized on a global basis.FM provides testing and certification services include:
1. Product Certification - FM to the fire equipment, electrical and electronic equipment, dangerous places facilities, fire survey, signal equipment, electronic equipment, building materials and other products issued by the certificate;
2. Standard detection - FM provides the manufacturer with a standard test service for a single characteristic of the product;
3. ISO 9000 registration - FM is the ISO 9000 registration body, for enterprises to ISO 9000 system audit;
