Our Factory FangLing carries a Quality Management System certified in accordance with the ISO 9001:2015 standard. The well-deserved certification is the result of high and consistent standards of processes, which is reflected in the high quality of the tube products.
An independent quality assurance department is responsible for work procedures required to ensure that manufacturing processes are carried out in accordance with international technical delivery conditions given in ASTM, ASME, EN, IS and customer specifications.
To guarantee high quality, FangLing procures its raw material from top-notch vendors of international repute. The manufacturing is carried out under strict process control and monitored throughout the production process to ensure total conformity to requisite specifications.
All through the process and finally before dispatch, uncompromising and stringent tests are carried out as per the standards specifications or customer specific requirements.
Every single piece of tube is subjected to a thorough visual inspection by trained staff to detect dimensional inaccuracies, surface imperfections etc.

To ensure complete identification and traceability even after supplies are effected, all the information as required by the standards, i.e. brand name, size, grade, specifications, heat number is marked on all the pipes and tubes.
