OUR QUALITY POLICY:
At BTU CONTROL we offer the heat treatment and/or effort relief service, maintaining the commitment to satisfy our clients and our interested parties, complying with their contractual requirements and applicable regulations, ensuring the integrity of our employees, the conservation of the environment, through the continuous improvement of our services and processes
SERVICES.
For the execution of our services we use electrical methods, through flexible resistances and ceramic and / or combustion, through high-speed burners, where the combustion gases carry out heat transfer by forced convection, with these methods we have the capacity and ability to perform the heat treatment from a pipe-to-pipe welding, of smaller diameters, to large-sized containers.
ADVANTAGES OF CONTROLLED PREHEATING
1.- Reduction of stress level due to thermal effect.
A controlled and homogeneous preheating reduces the temperature differential between the welding area and the base metal, minimizing the tendency to fracture.
The structural stresses due to thermal stresses originate due to the abrupt enfolding in the welding application area, being able to cause fractures during and after the welding process by the contraction between the metal of the contribution area and the base metal.
2.- Hardening reduction of the welding area.
The metal of the weld and the adjacent area and area affected by the weld can cause hardening or fractures when they are at high temperature and their cooling is very fast and uncontrolled.
The controlled preheating in the welding zone and the zone affected by the heat, prevents the excessive hardening of both zones by an uncontrolled cooling.
3.- Reduction of fractures and pores caused by hydrogen.
A controlled preheating helps to eliminate the humidity allowing the volatilization of the hydrogen and avoiding considerably the probability of fissures or pores in the welding.
4.- Temperature compensation.
The homogeneous and controlled preheating, before and during the welding process in parts with greater thickness in carbon steel and different alloys that have high thermal conductivity results in a better melting capacity of the metals.
ADVANTAGES OF PWHT (Post Weld Heat Treatment, Relief of Efforts)
1.- Increases ductility and decreases hardness.
It reduces the mechanical and structural stresses due to residual tension and elasticity, in the steels submitted to the welding process, "softening" the material for greater resistance and operating performance
2.- Minimize fractures.
Pipes or containers for high pressure, structural steel or steel components subjected to welding process can fracture even under normal working conditions if there are defects in its structure such as knots, stress points or residual stresses. The PWHT, by relieving residual tensions or stresses, and tempering the metal structure, improves its resistance to fractures.
3.- Increases the resistance to corrosion.
Fractures and cracks due to corrosion or the use of caustic materials in pipes, vessels, boilers or other process equipment subjected to the welding process, can occur when in contact with substances such as hydroxides, hydrogen sulfates, nitrates, etc. The corresponding PWHT in these process equipment and / or pipes, reduces the level of residual stress, providing greater resistance against corrosion than in those not heat treated.
4.- Increases and balances the mechanical resistance.
Welding in complex structures causes stress points or stresses within the structure of the metal, which if subjected to machining processes (turning - forming) without stress relief or stress relieving, its deformation is possible due to the destabilization of the efforts contained in the molecular structure of the metal, when performing any mechanical work on them.
