This shall be achieve through the implementation of an effective QMS with the involvement of all concerned.
Unmatched quality
Surya Roshni prides itself on its uncompromising quality standards that few other manufacturers can match.
It is a process that begins as early as the raw material stage. Steel strips are assessed for its mechanical strength and consistency. At every subsequent station along the manufacturing line, our engineers employ sophisticated equipments and techniques to ensure not only the defect free quality of pipes but also their optimal performance under the most adverse conditions. The inspection procedures evaluate each pipe for surface finish, perfection of weld, correct diameter, wall thickness, length and weight.
Modern Laboratory
A fully equipped metallurgical laboratory tests materials for their ability to withstand reactive processes. Hydro testing of pipes is undertaken to detect leaks and fissures prior to galvanizing and threading. Destructive testing of pipes entails performance examination of the weld as well as their tensile and compressive strength.
The constant emphasis on high quality guarantees a long trouble-free service life to the pipes-without breakdown and without corrosion.
TESTING AND QUALITY CONTROL FACILITIES
Besides the numerous quality assurance measures during the manufacturing process and various inspection points, the following facilities are available for ensuring stringent quality standards.
1. Universal Testing Machines (Digital)
For material testing (mechanical properties)
2. Eddy Current Testing Machine(NDT)
For on line flaw/inperfections detection on welds.
For checking strip laminations and flaw detection on welds on pipes in automode. 100% weld length and parent metal to detect flaws or imperfections, if any.
4. Metallurgical Microscope
For checking and evaluating the grain structure of material, heat affected and weld zones.
5. Vickers Micro Hardness Tester (Digital)
For checking micro & macro hardness on weld, heat affected zone and base metal.
6. Digital Ultrasonic Thickness Gauge
For checking wall thickness of pipes.
7. Mandrills and Fixtures
Reverse bend test
8. Impact Test Machine (Charpy v Notch)
For checking energy absorption test on materials.
9. Bending Machine
For pipe bend test
10. Drop weight tear test
For evaulating the sheer
areas of materials.
11. Hully computerised Japanese Spectro Meter
For carrying out chemical analysis
12. In house fully equipped laboratory
For chemical & Mechinal testing
Apart from the above important testing machines, we have online temperature recorders for seam normalizing auto pressure recording for hydraulic test pressure and many other sophisticated measuring instruments to ensure best quality of our products
The trained and committed work
force ensures high quality of pipes made to various
national and international standards, including the
demand API 5L specifications (Licence No 0222, 0794)
& API 5CT specifications (Licence No. 1338, 1378)
Our Credentials to Quality Supremacy
Testimony to our capability
It is the most prestigious and stringent specification widely adopted around the globe for cross-country pipelines meant for the movement of oil & natural gas at a very high pressure.
• Even the flow of LPG for domestic usage is relied on API 5L standards indicating the requirement of the state-of-the-art technology to produce these pipes.
• API 5L is the barometer of the Quality Orientation of a pipe-industry because of the use of API 5L pipes in most sophisticated applications where a minute deviation in quality could lead to hazards0
Confirmation of our quality competence
The Steel division of Surya Roshni Limited has been awarded the prestigious ISO-9001:2008 Certificate by DET NORSKE VERITAS (DNV) certifying that the quality system of the company at Bahadurgarh has been found to conform to the quality standards ISO-9001:2008. This Certificate is valid for manufacture and supply of ERW steel tubes (Black & Galavanised) and CR Strips. This accreditation by the International Agency is added confirmation to the competence of the company to deliver quality products.
