The overview of Online leak sealing training
 

1. Technology feature:

Online leak sealing technology is a maintenance technique. Whenever there are leaks on equipments, pipelines, flanges or other system components, with this technique, the leakage can be eliminated quickly and securely to keep the equipment operating normally without production shutdown.

2. The technique characteristics:

(2.1) Do not affect normal production, which remains the original working condition.

(2.2) No need to do special treatment at the leaking position before the sealing operation, which could make the operation more convenient, simple, and faster.

(2.3) Do not destroy the original sealing structure, while, the new sealing structure is easy to dismantle.

(2.4) Do not impose extra stress on the defect position but give it enhanced protection, which could ensure the equipment to stay safe and reliable.

(2.5) Do not waste maintenance expense or cause serious fatal accidents by eliminating the leakage of flammable, explosive, toxic and hazardous medium, which brings a great economic and social benefit.

(2.6) No need shutdown the plant production,no need slow down nor go down the system pressure while repair leaks.

3. The application scope:

The applicable pressure: -0.1MPa~35MPa ；

The applicable temperature: -180℃~800℃；

The applicable medium: variety of mediums；

The applicable industries: petroleum, chemicals, power, metallurgy, medicine, chemicals,gas,oil, water supply and heat supply, etc.

4. Coordinating and complementary role of technology components:

Online leak sealing is a kind of comprehensive technology, it is consist of 4 parts:special sealants,leak repair clamps,injection tools and operation skills,which could reach its satisfactory sealing result, only when its four components coordinate with each other then can work out well on the leaking location.

5. Technology development level:

The beginner of this online leak sealing technology is Furmanite,and it was introduced into China 30 years ago.

After the years of research by the relevant personnel in our company, online leak sealing technology has passed the technical appraisement to fill the gap in 2000 and it spread all over the China. Presently, it has been widely applided in the process industry of the petrochemical, chemicals, metallurgy, electric power etc. It plays important role in maintaining the safe and long-term running, obtaining a great of economic benefit and eliminating the environmental pollution. In addition, the intensive study in the technology composites of sealant compound, clamp, special tools and sealing technique contributes to the bringing its integral level up to the international advanced.

6. The technique application management:

(6.1)In order to ensure the safety of the equipment and the personnel during the work progress, the online leak sealing technique was included in the scope of the national regulatory of the special equipment operation.

(6.2)It stipulates that the online leak sealing personnel ought to pass the exam of the Online Leak Sealing Training, and after been qualified to obtain the Certificate of Special Equipment Operation Personnels.

(6.3)The corresponding management criterions have been issued , which stipulate the procedure for the application of the work certificate, the determination of the examination institution, and the provisions of examination assessment (TSGR 6003-2006) and retrial provisions, and so on.
