Metals International Limited is a worldwide leading company specializing in insulation joints.

Description

Monolithic Insulation Joint is composed of the following parts: upper and lower conduits,sleeve,

insulating part, seals and insulating coat. Insulating part and seal are fixed where upper and lower

conduits are joined oppositely, which forms double sealing structure possessed of insulating performance.

Groove welding is applied to sleeve, or it is directly welded with upper conduit, in this way, insulating

part and upper and lower conduits are sealed inside firmly, and it also improves mechanic performances

such as pull resistance, bending resistance and stress resistance.

Design Specifications

Monolithic isolation fittings shall be boltless and completely factory assembled in accordance with the

appropriate requirements of ASTM, API, DIN and BS codes. All welds shall be butt weld construction.

The dielectric isolation material shall be a thermosetting fibreglass epoxy material. Sealing shall be by

two static, self energized O ring seals housed in accurately machined grooves, fully protected from

cavitations in full compliance with ASME design codes. Interior and exterior coating shall be a two part

epoxy with a thickness of 12 to 15 mils to within 2in of each end. Testing shall be Electrical (5kv, 25

Mohm), Hydraulic ( 1.5 x O.P.) and Weld (Ultrasonic/Magnetic Particle/Dye Penetrant).

Eliminates Short Circuits Bolts, sleeves and washers - the major source of short circuits in most isolation assemblies - are

eliminated with the isolation fitting.

Eliminates Field Assembly The isolation fitting is completely factory assembled and tested. There are no flanges, gaskets, nuts, bolts,

sleeves or washers to handle and consequently no fluid leaks due to improper field assembly.

Is Coated Both Internally and Externally A two part epoxy is sprayed to a thickness of .010-.012in (.25 to .30mm) to within 2in (50.8mm) of each

weld end

Is 100 percent Hydrostatically Tested All fittings undergo hydrostatic and cyclic pressure tests at 1.5 times rated operating pressure in

accordance with the latest ANSI standards. Testing is conducted between plates or end caps to ensure the

most arduous conditions.

Is 100 percent Electrically Tested All fittings undergo an electrical resistance and voltage test prior to shipping.

Is Completely Weld Inspected All fittings undergo a weld inspection with combinations of ultrasonic (UT), magnetic particle (MT) and

dye penetrant (LT) on all welds. In addition, X-ray tests can be conducted upon request.

Is Manufactured In Accordance With ISO 9001 2000 Quality Assurance Control over all stages of production is ensured by close adherence to an in-place and ongoing ISO 9001

2000 quality assurance program which is constantly monitored and subject to periodic audit.

BENEFITS ONSHORE PROJECTS

* To limit spread and hence cost of cathodic protection current to those pipes that need to be effectively

and economically protected by the main cathodic protection system.

* To isolate a pipeline and to ensure that cathodic protection or stray currents do not cause increased

corrosion.

* To electrically "split up" long pipelines into distinctive cathodic protection system.

* To provide protection against earthing currents at domestic and industrial premises where the PME

system is in use.

* Saving in the overall cost of corrosion control system is just one of the benefits of using isolation joint.

The isolation joint comes with an 'O' seal ring for an added safety and strength.

OFFSHORE PROJECTS

* In riser pipes and offshore structures to isolate the pipeline cathodic protection system.

* At fields "tie-ins".
