Foreword
This standard was developed with reference to DIN 4925-1..1999 "Part 1 of Wellbore Tubing and Sleeves for Wellheads with PVC-U
Sub-DN35 to DN100 threaded pipe ", DIN4925-2..1999" with threaded hard polyvinyl chloride (PVC-U) wells with shaft pipe
And Sleeves Part 2 DN100 to DN200 Trapezoidal Thread Tubes, DIN 4925-3..1999 "Threads with PVC-U Water
Well wall pipe and casing Part 3 DN250 to DN400 trapezoidal thread pipe "series of standards, GB/T 10002.1-2006
"Water-based rigid PVC (PVC-U) pipe", and according to China's actual production and application were modified and added.
This standard compared with DIN4925..1999, the main differences are.
--- According to the actual needs of pipe nominal diameter from 42mm ~ 450mm expanded to 110mm ~ 630mm;
--- Increased product physical and mechanical performance requirements;
--- Increased system suitability requirements;
--- Increase the inspection rules and signs, packaging, transportation, storage requirements.
