Tolerances for Threaded Fittings
The dimensions and tolerances of threaded fittings in accordance
with ANSI/ASME B16.11 as follow table. We will know if the products
are qualifed based on it.
High Pressure Pipe Fittings Supplier
When the threaded fittings are finished manufacutering, our workers
will do the marking which cover product name, type, material grade,
size, pressure ratings, thread type, standard and heat No.
After the marking, they will surface them with anti-rust oil
againest the rust duing the shipment, then start to package after
done that. Firstly, wrapped them with plastic foam. Secondly,
lining up them into carons and make a list. Finally put all cartons
into woode case and stick the shipping mark.
Inspection services
- Visual the surface. Such as dents, die marks, porosity, undercuts.
- Check the marking. Such as name, type, size, material grade,
pressure, heat No.
- Measure the size. Such as diameter, thickness, height of center or
end to end.
- Test the thread of threaded pipe fittings by Go/no Go Gauge.
