Arm & Hammer Forgings Products Quality

We are an ISO 9001:2008 certified organization, which speaks of our commitment to quality and perfection. The quality certification is a testimony to our efforts at monitoring and improving accuracy of production by focusing on “procedures” and “work instructions” in managing daily work.

There are quality inspection procedures which are in-built into our system at various stages, beginning with raw material purchase up to pre-shipment inspection. Adhering to the principle of quality control, Arm & Hammer Forgings Pvt. Ltd. maintains full traceability of all its products. Each single piece is permanently marked with logo/brand name, standard code, size, material number and heat number.
The mature quality management system has helped us in achieving high levels of customer satisfaction, staff motivation and continual improvement.

Quality Inspection

Experienced inspection team of AHFPL entire quality control procedure of each single order. All inspectors are well trained and have rich product knowledge & inspection experiences. In order to make the inspection result more dependable, various Non-Destructive Testing (NDT) methods are used, such as:

Visual Inspection

Dimension Checking

Chemicial Analysis

Hardness Test

Certain tests which cannot be conducted at our laboratory are sent out to notary public labs for further testing. After every inspection, the senior engineer certifies whether an item has a pending problem or is fit for shipment. Detailed inspection reports are filed for tracing and Mill test Certificate is released to customers.
Our constant focus on meeting quality standards and customer requirements guides us to organize our quality procedures and systems which encompass the following:
  • Organisation
  • Processing System
  • Machining
  • Testing
  • Finishing
  • Marking
  • Certificate
We have a quality control department handled by a team of Q.C. experts whose work is to maintain all the records & supervision of Q.C. Inspectors.
While selecting raw material we carry out a physical and chemical test. After acceptance of it, a control number is issued which is marked on whole of the material that is to be used. At the time of forging and forming of flanges, fittings etc same control number is transferred to further operation. After final forging or heat treatment a batch number is allocated to a lot and this batch number is stamped on each pipelining component. Time and date of final forging is also mentioned on the temperature chart.
After final heat treatment process, all the pipelining components are sent for machining that includes O/D and I/D matching as per dimensional codes. A expert quality control engineer keeps constant vigil on every machining operation. All the machining is carried out as required by the codes.
In this step, three types of testing are performed : Tensile testing, Hardness testing and Impact testing. In tensile testing, sample is taken from the pipelining components in accordance with codes as required by purchaser on universal testing machine calibrated & approved by the authorized inspection agencies. In hardness testing, results are recorded in separate register and it is performed on atleast 10% of whole lot. Impact testing is carried out on low temperature fittings covered by specification ASTM A420 WPL grades.
After pickling and passivating all pipes, tubes, fittings etc., scale is removed that is formed during forging operations. Finally dimensional check is carried out and recorded.
After the final dimensional check each fitting is marked for size, schedule, fitting specification, heat mark & batch number.
All of our pipelining components supplied to the purchaser are furnished with manufacturer's test certificate which includes data i.e. raw material composition, heat treatment done, heat mark, batch number, hardness value, chemical & physical test results, radiography results, size, schedule, specification and quantity supplied.
