What kind of thread does Ward pipe fittings use?
Length of thread also applies to plain fittings. For center-to- face dimensions, see fittings tables. Ward Class 150 Malleable Iron Fittingsare made with the most sophisticated metallurgical and processing controls avail- able. Iron samples are continuously analyzed using spectroscopy to conform the material quality.
What kind of threads are used in wrought iron fittings?
All fittings shall be threaded with American National Standard Pipe Threads (ANSI/ASME B1.20.1) and shall have taper threads, except wrought couplings and wrought caps in sizes 1/8, 1/4, 3/8 and 1/2, which may have straight threads. CONVERSION FACTORS

A hub system connects pipe sections, originally using melted lead to seal the joint against wastewater leaks or sewer gas odor leaks. The cast iron pipe hub and stub were wiped with oil to remove water, avoiding a dangerous steam flash when lead was poured into the fitting.
Why do Ward pipe fittings have chamfered openings?
The threads have an accurate form, thread length and straightness to allow them to easily engage threaded pipe. In addition, Ward fittings have a chamfered opening to allow faster and easier pipe engagement. This feature also protects the fitting threads from damage during handling.
Which is the European standard for threaded pipe fittings?
BS EN 10242 is the British European Standard for ‘Threaded pipe fittings in malleable cast iron’ first published in August 1995 and very closely follows ISO 49. All European Standards have to be adopted by the member countries of the EU and any conflicting national standards withdrawn.
