PPWE Welding Insulation Chamber can allow hot work to be carried out in a SAFE, CLEAN and HAZARD FREE manner, without the need to shutdown platform.

The ADVANTAGES of PPWE :

• Isolates the welding area
• Contains the heat source
• Confines the spark and splatter
• Eliminates the need for Shut-Downs
• Provide a positive barrier between welding and flammable

PPWE Specification:

• Constructed from light weight flame retardant – fiber glass material, Industrial type zip fasteners (c/w togles both inside and outside) and an integrated Velcro sealing tape attached.
• Standard Panel Size 1 Meter x 1 Meter or 2 Meter x 1 Meter.
• Two (2) Off sleve type penetration panels; 2 Meter x 1 Meter emergency rip and run panel.
• Panel also made from a matrial that let sufficient ambient welding and flammables.
• Manometer to show positive pressure reading 20 – 60 Pascal.
• Zone-2 intrinsically safe electric blowers; capable of inflating the PPWE and maintaining the positive pressure and sufficient volume of air.
• Two (2) door air-lock system; to minimize air loss during entry and exit.
• Spare additional panels are supplied with each PPWE.
• Repair kits for minor tears and abrasion supplied.

We provide a Periodic inspection on lifting gears and lifting equipment, this include but not limited Drilling Equipment & Tools, Pedestal, Overhead Crane, Slewing Jib, Fixed Lifting Equipment and Loose Lifting Equipment.

We offer a full range of an Unmanned Aerial Vehicle (UAV) service for Industrial purpose.

We can deliver our UAV equipment for special task such as Flare Inspection (Visual and Thermal Oxidisers), Electrical Tower Inspection and Chimney Inspection including emission measurement.

We develop SAFE, a tool to record all identified possible risk and degrees or severity of probability, SAFE report are provided to you prior deployment of our UAV inspection.

Historically, volumetric survey were done with somewhat manual approach, theodolites used with someone walking over stockpiles taking spot measurement. Modern Aerial Survey techniques utilizing PPK Geo-referenced Photogrammetry are replacing these old method for many compelling reasons.

With PPK Aerial Survey Method can be provide the result equivalent to 368.400 datum points and materially more accurate with tolerance which only around +/-1%.

For reporting, we provide computer generated 3D models with down to 3 cm XYZ, which processed with Digital Evaluation Models (DEM’s), it’s not just suitable for stockfiles, but also suitable for volume survey and modelling quarries and open pit mines.

PT. Gistek Marco Indonesia, provides Non-Destructive Test and Welding Inspection services for a diverse range of industries. We help you to ensure the reaility , safety and integrity of products, equipments or plant assets with our NDT services.

Ultrasonic Test, these method can be performed on all type of materials and its application include :

Flaws detection such as inclusions, cracks and porosity. your

Determining the thickness of test objects, particulary in erossion or corrosion monitoring.

Magnetic Particle Test, these method can detect surface & subsurface discontinuities in Ferromagnetic matrials. These method is widely used in all industry sectors to inspect a variety of products and engine components (Castings, Forgings and Weldments).

Liquid Penetrant Test, also known as Dry Penetrant Test, these method used to located surface breaking flaws such as cracks, porosity, laps, seams and other surface discontinuities. LPT can be applied to both Ferrous and Non Ferrous matrials (Metals, Plastics or Ceramics).
