We should check the following aspects about Ductile Iron Pipe Fitting.
1) Mold management, mold should be very good repair and maintenance, can not be clearly flawed, so as not to affect the surface quality of the pipe.
2) Production capacity, there should be a large enough warehouse to store the fittings used conventionally, which should be paid attention to in the inspection record of the buyer. It is very important to have the ability to supply timely.
3) Material usage should be stable and clean. Some manufacturers too much use of recycled materials to reduce costs, will inevitably lead to quality problems.
4) Pipe weight control system, process should ensure that the weight of the pipe within the standard tolerances.
5) Dimensional testing, the size of each pipe should be checked with a standard measuring tool to meet the required tolerances.
6) Hydrostatic test, each pipe, regardless of its size, should be carried out hydrostatic test or equivalent test.
A good Ductile Iron Pipe Fitting supplier will know that and provide high quality of ductile iron pipe fitting.
