| Specifications︰ | All pipe fittings are subject to strict in-process inspection at each stage of the production process, from starting material handling to finished product shipping. They are visually examined for conformity to company specifications and checked and tested in accordance with applicable ASTM, ASME, MSS, DIN, EN, and JIS codes and standards. Upon request, officially certified test agents can be called in to witness the inspection procedures.
Material Receiving Inspection
The material inspections are carried out as follows.
1. Dimensional Inspection
Dimensions are checked at each end of the purchased material.
2. Visual Inspection
Surface check to ensure that material is correct and suitable for production of fittings.
3. Collating
Tests are done to ensure that the chemical composition and tensile properties of the described items are exactly as shown in the material certificates.
In-Process Inspection
Pipe fittings are manufactured from carefully selected materials of the finest metallurgical quality on well-controlled jigs, tools and molds. In order to ensure that all fittings meet quality specifications, the following in-process inspections are performed.
-Visual Inspection
-Dimensional Inspection
-Shape Inspection
-Hardness Test
-Temperature Check
-Processing Conditions Check
-Material Identification (marking)
-Other Inspections
Final Inspection
All the pipe fittings are subject to the following final inspections before they are packed and delivered.
1. Visual Inspection
Both internal and external surfaces are checked to confirm they are smooth and do not bear any harmful defects.
2. Dimensional Inspection
Done to ensure that all fittings are in conformity with dimensional tolerances of relevant Codes and standards.
3. Special Inspection
Non-destructive examinations and mechanical tests are performed as per customer's Request.
4. Certification
Inspection certificates are issued in accordance with international specifications unless otherwise requested by customers.
Third-Party Inspections
All our fittings subject to this inspection are made from starting materials stipulated by the regulations of the inspection body, e.g. BV, LR, DNV, SGS, etc. The staring materials and finished products are inspected for appearance, dimensions, and conformity to designated codes and specifications. The inspection body witnesses and certifies the inspections and issues certificates or report of findings to customers.

All the products has a strict quality system enforced to control the identification of its product from material stage all the way to product packing and delivery. Each product is given and records are made from the first minute that a shipment of pipes are received into the warehouse.
An unique stenciling and marking with specification and material heat number details starts traveling with the material from the material cutting step. And measures are taken to ensure that no products are moved between steps such as material to forming, forming to heat treatment, heat treatment to machining, etc.
