Pipe Repair Clamps

Pipe Repair Clamps Manufacturer in India

We provide you with the superior quality Pipe Repair Clamps manufacturer in India. A leaky water or gas pipe can cause significant difficulties, so it should be repaired as soon as possible but in a safe and long-lasting manner to prevent additional water or gas loss. Our stainless steel pipe fixing clamp can be used to fix broken or damaged pipelines permanently.

Pipe leak clamp is a type of device used to repair pipe clamp hydraulic and seal a leaky pipeline. This is a long-term mending method. This procedure can be used to repair locally corrupted, damaged, and cracked pipes.

Pipe repair clamps are designed and manufactured by our organization. Our pipeline clamps may be customized to fit a variety of dimensions and pressure ratings. Tie-in, hot tapping, repair, leak sealing, and reinforcing are just a few of the uses of hydraulic pipe clamp. In our high-tech machine shop, we precisely machine our pipe repair clamps and hydraulic pipe clamp manufacturer in India.

The transportation and transfer of fluids from wellheads to offshore process system pipework and pipelines to refining facilities are critical to the oil and gas industry’s safety, efficiency, and economic sustainability.

What is the purpose of the Pipe Repair Clamps Hydraulic?

The high pressure pipe repair clamps hydraulic are essentially a pre-rolled stainless steel plate with a rubber lining secured with welded bolts and nuts. The clamp fasteners‘ tensile strain is translated to radial pressure on the rubber liner, ensuring a secure seal.

Key Features

• Lightweight strap clamp for repair or intervention in a specific area
• Self-energised pipe-to-pipe sealing
• Installation is quick and straightforward.
• The low-profile design enables installation in tight spaces.
• Repair (Blind), Hot Tap (Flanged), or Encapsulation (Capped) seal housings are available.
• Low and high-pressure applications are both possible.
• Their design allows components to be reused for different pipe geometries.
• Sealing material is provided according to the application (NBR, HNBR, Viton, HPU)
• Carbon steel that complies with NACE standards is standard; alternative materials are available upon request.
• Single or multiple seal configurations are available.

Pipe Repair Clamps

We have a wide range of superior quality Pipe Repair Clamps Manufacturer in India. We have all thermoplastic piping materials and working successfully for over 60 years.

When is it appropriate to use a repair clamp?

Repairing a leaking pipe Clamps can be used in a variety of scenarios on gas or water pipes where there is a leak, and immediate repair is required:

• Holes in pipes made of asbestos cement, steel, or cast iron
• Asbestos-cement and cast-iron pipe breaks
• Asbestos cement, steel, cast iron, and PVC pipe cracks
• Damage caused by a service crane or branching portions that have been broken off
• Leaks caused by corrosion

Pipeline and process pipe inspections regularly can reveal faults or leaks that require modification or repair.

Clients and our organization work together to ensure that the unique requirements of any replacement or repair solution are correctly understood and risk assessed. The solutions are designed to meet the system’s rigorous design and operating parameters.

Our pipe repair clamps manufacturer is designed to fit a wide range of applications for onshore, topsides, and subsea installation. Our cutting-edge repair and maintenance solutions help operators prevent or decrease downtime while also lowering risk and spending.

Our company offers various caisson handling equipment for securing and recovering broken or superfluous caissons safely and efficiently. Internal and external lifting tools are available in various sizes to allow for the safe and controlled removal of caissons.

THE PROGRESSIVE SEALING EFFECT

The progressive sealing effect is a unique and patented feature of the PETRONTHERMOPLAST gasket.

  • As the pressure in the pipe increases so does the force on the sealing lips, due to the flow through the pressure equalisation channel.
  • The gasket is not subjected to any great loading thanks to the minimal installation torque applied. This results in continued elasticity and a long coupling life expectancy.
  • The free space between the sealing lips serves as a„reservoir“ for the gasket in the event of temperatureswings.

THE PROGRESSIVE ANCHORING EFFECT

PETRONTHERMOPLAST pipe couplings are used on conventional plain ended pipes without pipe end preparation being necessary.
The progressive anchoring effect of all GRIP products is a unique and patented feature:

  • As the bolts are tightened to the specified torque, the specially shaped teeth in the anchoring ring bite into the surface of the pipe. An axial restraint connection is created.
  • Should the axial loading on the pipe increase due to increased internal pressure or exernal influences, the teeth bite even deeper into the pipe to compensate.
  • There are PETRONTHERMOPLAST anchoring systems not only for hard surfaces such as iron, copper and steel but also for softer surfaces such as aluminium and plastic.
  • Through differential hardening, the anchoring ring retains flexibility in service.

STRESS-FREE JOINING

The sealing and anchoring functions are independent of one another in PETRONTHERMOPLAST pipe couplings.

AnchoringThe spring effect of the housing and the anchoring ring result in a flexible gripping connection. The housing which bridges the pipe ends imparts no forces and thereby keeps the stress on the various components to a minimum. The pipework is therefore not rigid but is flexible at every joint.

Sealing

The gasket is positioned on the surface of the pipe and enables the pipe ends to move freely.

FEATURES AND BENEFITS

UNIVERSAL USE

  • Compatible with almost any traditional jointing system
  • Joins pipes of the same or dissimilar materials
  • Leakproof joint for liquids, gas and solids
  • Quick and simple repairs of damaged pipes without service interruptions

RELIABLE

  • Stress-free, flexible pipe joint
  • Compensates axial movement and angular deflection
  • Pressure-resistant and leak-proof even with inaccurate pipe assembly
  • Dampens water-hammer, vibra-tion and structure-borne noise

DURABLE

  • Progressive sealing- and anchor-ing effect
  • Corrosion- and temperature resistant
  • Good resistance to chemicals
  • Long service life

ECONOMICAL

  • Pre-assembled design ensures simple and rapid installation
  • For use on plain-end pipes with-out the need for costly pipe end preparation
  • Simply cut pipes to length, center coupling and tighten bolts with a torque wrench
  • No special assembly tools and set-up times

EASY HANDLING

  • Detachable and reusable
  • Maintenance-free and trouble-free
  • No time-consuming alignment and fitting work
  • Does not create a heat or fire haz-ard. The coupling can be fitted in special areas where there is a fire risk and also in confined spac-es without the need for special equipment

SPACE-SAVING

  • Compact design for space-saving installation of pipes
  • Allows the use of low profile pipe insulation
  • Low weight compared to tradi-tional methods such as flanges

LIFE EXPECTANCY

The life expectancy of PETRONTHERMOPLAST pipe joints and PETRONTHERMOPLAST repair clamps fitted with sealing sleeves made of EPDM, NBR or FKM/FPM extend to 25 year or more, provided that recommended storage procedures are correctly adhered to.

Application conditions

Increased temperature
The max. application temperature of EPDM is 125°C/250°F and NBR 100°C/230°F, but as a consequence the life span can be reduced. In
addition dynamical and chemical stress has to be taken into consideration. For different applications please verify the life expectancy with the manu-facturer.

Low temperature:
Subject to performance requirements the elasticity of PETRONTHERMOPLAST sealing sleeves is sufficient to cope with temperatures down to -30°C/-22°F. There is a loss of elasticity below this point which, under the stress of additional dynamic loading, can result in disruption of the elastomer.

The coupling casing and the anchoring ring (GRIP) completely enclose the sealing sleeve and therefore protect it from UV irradiation.

Because of their progressive sealing effect, PETRONTHERMOPLAST sealing sleeves require a smaller tightening force and therefore subjected to less stress than, say, a flange seal. The elasticity and hence the working life of PETRONTHERMOPLAST sealing sleeves is consquently maintained over a longer period.

Storage

Recommended long term storage conditions:

  • Avoid exposure to direct sunlight by storing inside
  • Store at consistent temperatures (maximum 40°C/104°F)
  • The relative humidity should be kept above 50 %
  • Protect from dirt or soiling
