World First FRL-Free Torque Gun with LCD Display- Digital JGun

The new digital jGun series from HYTORC is the world’s first torque-adjustable pneumatic multiplier with a digital readout and FRL-free operation. Unlike other systems that require a separate filter, regulator and lubrication system between the air line and the tool, the patented design of the digital jGun eliminates the need for this add-on for the highest level of portability and convenience.


Applications-.

Benefits-
1. Digital Readout
The digital jGun is the world’s first industrial torque multipler with a digital readout for instant confirmation of selected torque. No more pressure-to-torque conversions or calculations. Select between ft-lbs and Nm or PSI and BAR.

2. Built in torque Adjustment
Other pneumatic multipliers require the use of a separate air regulator to adjust the output. The Digital jGun is the first of its kind with an on board air regulator for simple torque adjustment with a twist of the connector at the bottom of the handle. This feature is especially convenient when switching from tightening to loosening, giving you the ability to quickly adjust to full power for fast and easy break-out.

3. No lubrication required
The new motor featured in the Digital jGun is a workhorse designed for heavy industrial use. With maximum power to weight and a rugged corrosion resistant design, this motor eliminates the need for separate air filters and lubrication systems making the Digital jGun the most portable air powered torque gun on the market.

4.High torque Deliver- 
The Digital jGUN pneumatic torque wrench is designed to safely and accurately deliver up to 8,000 ftlbs of torque onto a fastener. This is accomplished using a patented planetary gearbox torque multiplier system and an appropriate reaction arm or HYTORC Reaction Washer™ and HYTORC Nut™

3 way to Tension the Load

What is Tensioning?
Tensioning is the direct axial stretching of the bolt to attain preload. Inaccuracies created through friction square measure eliminated. Massive mechanical effort to form torque is replaced with straight forward hydraulic pressure. the same load can be applied by tensioning multiple studs at the same time.





Tensioning needs longer bolts, and a seats on the assembly around the nut. Tensioning will be done victimisation clastic Bolt Tensioners or Hydraulic buggy.





There are 3 way to Tension:-


1.Heat
2.Hydraulic Tensioners
3.Mechanical Tensioners

1. Tensioning with Heat:-

Gas Bolt Heater:-

Objective:-
Correctly setup a gas bolt heater
Properly adjust oxy-acetylene flame
Correctly adjust air flow
Safely operate a gas bolt heater


Design:-
Heating causes a bolt to grow in length
Relieves tension on bolt
Gas Bolt Heater is machined from solid Stainless Steel
A single bolt heater can be adapted to fit most bolt sizes by changing the heating tube diameter and length

Operation:-
Select a heating tube that is 1/8” smaller than the hole in the bolt and approximately 3” shorter than the depth of the hole
Install heating tube in bolt heater
Use stainless steel reducing bushing for smaller heating tubes
Use high temperature thread compound
Tighten hand tight
Connect air line to bolt heater
Air pressure should be between 50-100 PSI
Set oxygen pressure to 14 PSI
Set Acetylene pressure to 7 PSI
Use Victor #5-W gas welding tip
Always use check valves
Adjust flame to obtain a carburizing flame
Carburizing flame has an acetylene feather
Insert bolt heater into bolt
Purge bolt cavity with air
Turn air valve off
Insert welding tip into gas bolt heater
Gradually open air valve approximately 1/8 turn
Observe color of heating tube through vent holes in gas bolt heater
Maintain a cherry red color by adjusting air valve
More air is cooler
Less air is hotter
For proper operation a balance of pressure must be maintained between welding tip and heating chamber back pressure
Excess back pressure will result in welding tip back-fire 
If back-fire occurs, close acetylene valve, remove welding tip from bolt heater, purge bolt cavity with air, and restart heating process

PRO’S:
Minimum Muscle

CON’S:
Hot
Slow
Inaccurate
Hard on Studs
Must have hole
Rough on gaskets

Why We Love TTX Square Drive Torque Wrench

 A torque wrench is a tool used to apply precisely a specific torque to a fastener such as a nut or bolt.A torque wrench is used where the tightness of screws and bolts is crucial. It allows the operator to measure the torque applied to the fastener so it can be matched to the specifications for a particular application. This permits proper tension and loading of all parts. A torque wrench measures torque as a proxy for bolt tension. The technique suffers from inaccuracy due to inconsistent or uncalibrated friction between the fastener and its mating hole. Measuring bolt tension (indirectly via bolt stretch) is actually what is desired, but often torque is the only practical measurement which can be made. 

TTX torque wrench provide torque from 228 Nm to 40194 Nm.Its Reaction Arm Mounted On The Square Drive Eliminating Torsional Force On The Cylinder. It Also Enables To Customize The Reaction And Suit The Application

4 Major Phases of Plant Turnaround

In any industrial plant, inspection and minor maintenance work are taking place “on line” but it has to undergo a scheduled process outage for the major maintenance work and this outage is referred to as “plant shutdown”. Turnaround management is primarily concerned with repair, replacement, alteration and refurbishment of malfunctioning items.


A turnaround is a cyclical process with four phases which starts with initiation and passes through preparation, execution and termination. 
The 4 Major Phases of Turnaround are as following-

Phase 1 – Initiation 

The initiation phase of the next turnaround must follow on from the present termination phase.
The initiation phase of a turnaround starts from the moment the senior manager considers the necessity of the turnaround and continues over a period of months. In some cases it continues for 20-24 months before the event. During this phase all parameters of the turnaround are defined in detail i.e. analyses breakdown and production problems from the historic data and past events. Strategic issues and objectives are addressed in this phase.
Some of the critical issues and activities are tabulated below. 


Phase 2 – Preparation

 Preparation is the most important phase of the turnaround process and may continue for a period of 3 to 18 months depending upon the scale of the event. Members of the preparation team accumulate a large quantity of technical and non-technical data to specify, schedule, resource and cost the large volume of tasks required to execute the turnaround event by validating and transforming those data into a set of plans. The work list is one of the most important elements of this phase and is the foundation of safety, quality, costs, equipment, materials, resources, logistics and turnaround duration. It contains an element of uncertainty as it involves some degree of prediction of the unforeseen activities related to plant equipment that can be minimised by systematic questioning as a part of an analysis of contingencies. Some of the typical questions used for the analysis are: What may go wrong? What faults are likely? What is the cost implication? How much time is required to set that right? What are the contingencies available? 
The preparation team along with the plant team challenges and validates the work list that is finalised by the turnaround manager. The plant team and TA team have to communicate regarding the requirements of the turnaround from time to time by means of a series of briefings involving each and every person across the levels.

Phase 3 – Execution 

During the execution phase all the planning and preparation are tested against reality and is characterised by the performance of a large number of people of different skills and disciplines within the framework of restricted money and time. Execution continues two to eight weeks, which involves co-ordination of all activities. It is characterised by close monitoring and controlling of event-wise schedule, safety, quality and cost.
There will be a designated person as a first person responsible for each and every sub phase. Single point responsibility ensures effective coordination and the designated person confirms proper completion of the previous stage of the task. Successful completion of the present task as per the specification and subsequently handing over to the next stage at the earliest possible time are also part of the designated person’s responsibility. The execution phase involves following critical issues and activities: 


Phase 4 – Termination 

The termination phase continues one to two weeks during which time the entire turnaround work is closed and performance is to be reviewed against the plan. It includes reviewing of all completed jobs and re-commissioning activities to ensure safety. 
This phase ensures that the plant is handed back in a fit condition while ensuring proper debriefing of every member of the turnaround organization to capture the lessons learned from the turnaround that may be useful for future requirement. De-briefing is also useful to control the change in plant operation that has happened due to turnaround. Cost and inventory statements are to be prepared. It is a most crucial phase as most of the accidents usually take place during start-up. Before handing over the plant it is required to clean the plant. Critical activities:
 • Start-up team cleans the site and removes all equipment especially brought for turnaround work.
• The plant manager takes charge of the plant after thorough inspection while the turnaround manager demobilizes the start-up team. 
• De-briefing can be arranged jointly by the plant and the turnaround manager. 
• The turnaround manager generates the final report.
