ZINC COATED GALVANIZED STEEL CLOSE NIPPLE WITH THICKNESS STD SCH40 SCH80

The close nipple is specified by the overall length including the threads. A close nipple has no unthreaded area

and is virtually unexposed when connected to two female fittings, Galvanized nipples are made from zinc-coated steel.

They are commonly used for outdoor and industrial applications, Galvanized finish helps resist rust in water, air, and

steam applications

Threaded nipples are used in commercial and industrial environments to transfer water, oil, gas, or air through

a pipe system. Threaded pipe nipples are fast and economical components that are easily added to these pipe

systems. In addition, close pipe nipples require no welding so the close nipple can be easily installed

Reference Standards

ASME B16.9 Specification for Butt Welded Fittings

ASME B16.9 specification is designed for butt welded fittings applied in industrial construction pipelines. Including elbow, tee, cross, cap, reducer, and etc.

Standard Scope

The standard includes specifications of NPS 1/2 to NPS 48 (DN15-DN1200) factory-made wrought butt-welded pipe fittings overall dimensions, tolerances ratings, test methods and markings.

Special Fittings

Special fittings here refer to special sizes, forms and tolerances that agreed between buyer and manufacturer.

Fabricated Fittings

Fabricated laterals and other fittings by circumferential or intersection welds are considered pipe fabrication could not apply this standard.

Units under ASME B16.9 shall be stated in both SI (Metric) and U.S. Customary units. Designation for size is NPS.

Reference Standards

It is not considered practical to identify the specific edition of each standard and specification in the individual references. A product made comply with a prior edition of referenced standards and in all other respects conforming to this standard will be considered complied.
