Street Elbows with Internal and External Threads
A street elbow with internal and external threads is a special pipe
fitting designed to save installation space. One end is female and
the other end is male. This unique structure allows it to be
directly screwed into another internally threaded pipe fitting
(such as a tee or pipe clamp), eliminating the need for a
connecting nipple. This not only reduces installation costs and
potential leakage points, but also makes pipeline layout more
convenient in compact spaces.
Material Properties of CF8M/316
The use of CF8M/316 stainless steel material provides excellent
corrosion resistance protection for the pipeline system. Compared
to ordinary 304 material, 316 can more effectively resist the
corrosion of chlorides and various industrial chemical media due to
the addition of molybdenum element. For applications such as
plumbing, this means that the fittings are less prone to rusting,
corrosion, and perforation, which can significantly extend the
service life of the entire pipeline network and reduce the risk and
cost of later maintenance.
316 Material and Standard Description
It should be noted that according to the ASTM A351 standard, the
official grade for casting 316 stainless steel is CF8M. Although
there is a slight difference in chemical composition between the
two, it is generally accepted in the industry to use materials
labeled with "316", which can meet the performance requirements of
CF8M. Similarly, although our product dimensions are based on
standards such as ISO 4144, they are mainly produced according to
widely accepted industry standards to ensure good market
applicability and practicality.
Casting Elbow Application of Plumbing
Class 150 cast internal and external threaded elbows are the
"problem solvers" in low-pressure plumbing and piping engineering.
It is the most ideal choice when a 90 ° angle needs to be directly
drawn from another pipe in a limited space. It is widely used in
residential and commercial plumbing systems, HVAC piping,
irrigation systems, and general industrial equipment to achieve the
most compact and efficient piping connections.
