We, Group 3A Trading Co., Ltd., are always on the look out to find the best possible partners to our customers’ benefit. Amongst them, one of our partners is a testing laboratory with the objectives to analyze in-house test results for mechanical testing, chemical composition testing and non- destructive testing (NDT). This laboratory then started servicing for various organizations. Development never stopped science. The laboratory was transformed into an independent company, which independence, allowed it to exercise its autonomy and fully utilize its knowledge and skills in analyzing metal qualities. Testing Laboratory process had built in the consolidation of continuous quality consciousness among technicians and engineers and improving proficiency.
Group 3A Trading Co., Ltd. has reached partnership agreement so that this research unit’s skills could be used for the very best in the shipping business. Through our partners, accredited metallurgic research center in Thailand, we can provide, amongst others, the following services:
- Mechanical Tests to support the customer in various sectors especially in Construction, Petrochemical and fabrication :
- Tensile Test
- Bend Test
- Impact Test
- Fracture Test
- Nick – Break Test
- Stud Weld Test
- Proof Load
Looking farther, Group 3A Trading Co., Ltd have asked its partners for additional possibilities. We can also provide:
Macrostructure Analysis is performed to access metal welding quality, casting formation, or identify natural imperfection which is normally found in the form of impurity or voids.
Microstructure analysis is conducted to examine internal structure of metal which has gone through polishing and etching processes. Through actual photo analysis varying from 25 to 1000 magnification, engineers can obtain preliminary production information.
Replica technique is the duplication of a surface structure of the inspected metal onto a special film. This is a non-destructive test as the study sample is untouched. This technique is best for large scale materials which cannot easily be transported such as boilers and oil refinery machinery.
Indentation hardness test measures hardness in Vickers and Rockwell.
Corrosion tests, such as Pitting corrosion and intergranular corrosion, are normally performed on stainless steel to measures its vulnerability to corrosion in order to access its quality before use.
- Macro/Micro Structure Analysis of Material and Weld Specimen
- Hardness Test
- Sulfur Prints
- Replica Technique
- Pitting Corrosion Test
- Intergranular Corrosion test
- Metal Flow/ Fiber Flow
- Yellow Mount Weld
Chemical Composition Analysis
Group 3A Trading Co., Ltd. can also provide customers chemical and metallurgical analysis, namely testing to find out the ferrite quantity by Ferrite scope or analyzing the specimen to find various values by Spectrometer. Moreover, we provide Mobile Spectrometer to analyze the specimen on customer’s site which can give result as correct and accurate as what customers get from laboratory.
- Mobile Spectrometer
- X-ray Fluorescence Spectroscopy
- Chemical Composition Analysis by Spectrometer Stationary
- Mining Analysis
Obviously the provided services would not be complete without Hydrostatic tests for :
- Pressure Vessel
Group 3A Trading Co., Ltd remains at your disposal for any queries you may have regarding the above. Please do not hesitate to contact us and we shall reply without any delay.
