Our Heat Treatment Activities Include

Post Weld Heat Treatment – PWHT

Post Weld Heat Treatment Services (PWHT) is defined as one of the heat treatment methods done after welding/machining to improve the chemical and/or mechanical properties of weldments / machined surfaces. In concept, PWHT covers many different potential treatments. However, in steel fabrication, the most common procedure used is Stress Relieving. It can be applied to pipelines, steel structures, vessels, boilers and tanks, etc. SOGEC has a variety of electrical and firing equipment to make sure that client needs are fulfilled with the utmost quality.

Pre-Heating

Preheating involves rising the temperature of the parent material locally, on both sides of the joint to a value as specified in codes. The need for preheating is usually determined by the applicable fabrication code and verified by the weld procedure qualification test. Preheat may be required as an aid to welding for one of the four basic reasons:

To control the rate of cooling.

To control the diffusion rate of hydrogen in a welded joint.
To reduce thermal stresses.
Compensation for heat loss.

Refractory Dry-Out

SOGEC has extensive experience in the field of refractory dry-out and in controlled heating and ventilation for the drying of specialized refractory linings used in process industries such as steel, petrochemical and aluminum industries. Our expertise in these areas ensures maximum effectiveness and minimum downtime of the equipment. Moisture is removed by strictly controlling heating rates to eliminate the risk of refractory damage by spalling and enhances the life of refractory linings.

Solution Annealing

Our heat treatment services for annealing various metals, such as steel, aluminum, and copper, improve the ductility as well as the cold working properties of all types of metals. It is a process in which carbides that have precipitated in the grain boundary are dissolved into the surrounding matrix by taking them to material-specific temperatures to allow carbon to go into solution and then quickly cooling them.

Hardness Testing

Having the correct hardness of steel structures and pipelines is critical in the field and in plants. SOGEC has the ability to conduct both methods of hardness testing which are available in today’s market, be it manual hardness or digital hardness. It is a major goal in quality assurance that can be achieved with SOGEC personnel having proven metallurgical knowledge and years of experience in this field.

Heat Treatment Engineering

SOGEC is able to prepare specific procedures and specifications to the parameters laid down in any code of practice. Skilled supervisors can make site appraisals and advise on suitable heat treatment methods.

Furnaces

SOGEC offers its in-house industrial furnaces, one in Dammam and another in Jubail to perform a range of heat treatment processes in it including Annealing, Ageing, Hardening, Solution heat treatment, Normalizing, and Stress relieving of various objects. We are also experienced in the fabrication of temporary furnaces on-site to facilitate the heat treatment of equipment that cannot be transported due to mobility restrictions.

Stress Relieving

The stress Relieving heat treatment process is heating subjects to a temperature below transformation temperature in order to relieve residual stresses in the material and lower the hardness values of the material which can cause distortions in the long term in the subjected items. Internal stresses in welded structures are removed by the stress-relieving method.

Internal Firing

SOGEC has a vast experience in on-site internal firing in the GCC region ranging from pressure vessels to tanks and boilers. In this method, the work-pieces or equipment are themselves converted into a furnace and are heated internally by diesel or gas-fired burners located at appropriate points, and the whole equipment is completely covered with insulation material to avoid heat losses. SOGEC has specialist personnel and portable equipment which can perform PWHT of this equipment in an efficient and convenient way.

Positive-Material-Identification - PMI

Positive Material Identification (PMI) quickly and accurately identifies the composition of more than 100 different engineering alloys onsite. SOGEC can perform PMI on virtually any size or shape of the pipe, plate, weld, welding materials, machined parts, or castings. We perform both X-Ray Fluorescence (XRF) and Optical Emission Spectroscopy (OES), two methods of conducting a PMI examination. Both methods ensure compliance with Process Safety Management (PSM) requirements and combined with the experienced personnel give you a reliable result.

Normalizing

The normalizing Heat Treatment process is heating a steel above the critical temperature, holding it for a period of time long enough for transformation to occur, and air cooling to make the material softer but does not produce material properties like annealing. Normalized heat treatment establishes a more uniform carbide size and distribution which facilitates later heat treatment operations and produces a more uniform final product. This treatment refines the grain size and improves the uniformity of microstructure and properties of hot rolled steel.
