HEAT TREATEMENT

HILTON METAL FORGING LTD have been in the forefront in executing variety of critical engineering jobs and have carried out specialized jobs in various organizations in India, especially in the petrochemical field including heat treatment. OVER 10 YEARS, HILTON METAL FORGING LTD is have been carrying out complete Fabrication, Erection Services for mechanical and instrumentation works for projects and shutdown jobs, many of which include Heat Treatment and NDT services apart from fabrication.

We at HILTON METAL FORGING LTD are conversant with stress relieving and heat treatment due to our extensive experience in fabrication, where heat treatment and stress relieving are integral part to completion of critical jobs.
HILTON METAL FORGING LTD is specialized in Heat treatment and NDT services, can build their own control units for S.R. Jobs and are capable of assembling various types of furnaces and operate and maintain the furnaces as well. We carry out Heat treatment / Stress reliving and L.S.R as per requirement at sites.

We can carry out Heat treatment processes through:-

Electrical Resistance heating method
Internal Heating using Gas / oil fired High Velocity Burner
Temporary Gas / Oil / Electrical fired furnace.

We can construct PWHT furnaces on site or off site and install the same at customer’s site. Further, furnace can be operated at customer’s site through our technical staff.

OUR TEAM
We have a highly talented team of personnel with wide experience in this field having carried out critical jobs at various sites in India. The team is headed by Mr. S.M. Dalvi,
(Manager, NDT.DIV.) Who to his credit has 15 years of experience behind him, having successfully carried out critical and bigger jobs and is ably assisted by Mr. Sanjay Wagmare, our metallurgist and our Designer For all type of Furnaces Mr.N.P.Kadale.

We can carryout all types of PRE HEAT, POST WELD HEAT TREATMENT AND ALL NDT jobs by any of the process viz. Electrical Resistance heating method, Internal Heating using Gas / oil fired High Velocity Burner or Temporary Gas / Oil / Electrical fired furnace.

HMFL EQUIPMENTS DETAILS:

Oil / Gas Fired High Velocity Burners

HMFL Oil or Gas high velocity burners are generally made of Stainless Steel, spark ignited type provide approx 350,000 kcal/hr and above for on site Heat Treatment. Automatic flame controlled nozzle combination with PID type controllers for automatic control of gaseous fuel .

And oil control valve units for manual controlled burners help achieve complete combustion through burners to improve efficiency.
Burner system can be operated with wide range of available fuels like LPG, Natural Gas or Propane for gas fired burners and HSD, LDO or Kerosene for Oil Fired Burners
Supervision of flame is monitored by flame relay and U.V. flame sensor. Ignition is activated
by direct spark ignition transformer with spark probe.

HILTON METAL FORGING LTD HEAT TREATMENT POWER SOURCE

Flexible ceramic heaters available in 25 kva and above capacity provide safe low voltage power of 60 to 85V powering flexible ceramic heaters for   preheating & post weld heat treatment [local S.R]

CONTROL

These units are housed in rigid steel frame of heavy gauge sheet steel cabinet, powders coated, insulated to class ‘h’ standards and are natural or forced cooled as required. The units are generally fitted with either 3 way or 6 way control   modules, controlled through Energy regulators and/or multi step ramp/soak control of thermal cycle through heavy duty contractors, operable on 380 / 440v. If need be this programmer can be operated manually.

THERMOCOUPLES:

The thermocouple shall generally of K / N type 12 SWG or 16 or 22 SWG as required to suit the job

TEMPERATURE RECORDING:

Temperature recording will be either by multi channel strip chart recorder or by dedicated data
logger with 6 / 12 / 24 points duly calibrated.
