SS 904L Instrumentation Fittings and ASME SB 649 904L Hydraulic Fittings manufacturer in India
ASTM B649 is a specification that covers low carbon alloys like grade 904L. This highly alloyed super austenitic stainless steel performs well in high temperature settings. The ASTM B649 UNS N08904 904L Ferrule Fittings are supplied either in a cold drawn or a solution treated state. Generally, the chemistry of the fittings under this specification is checked via a chemical or product analysis. And the properties concerning the tensile requirements of the Stainless Steel UNS N08904 Double Ferrule Tube Fittings like elongation, tensile and yield strength, are determined with the aid of a tension test.
For forged quality material such as the 904L Tube Fittings, a heat treatment process is waived. A hydraulic Stainless Steel 904L Tube Fittings are produced in a strict manner, such that it adheres to the pressure rating, type of construction and dimensions. The reason for stringent requirements of the ASME SB 649 SS 904L Hydraulic Fittings is because they are designed for use in industries dealing with high pressured environments. On the other hand, the use of 904L Instrumentation Fittings is for both low pressure and high pressure applications, where convey, measure and handle system flow, pressure as well as the temperature, while making provisions for system calibration. A typical sight in electrical conduit and plumbing systems, SS 904L Compression Fittings are more reliable in comparison to a threaded type.
SS 904L Compression and Ferrule Fittings in BSPP, BSPT and ISO / BSP thread forms
Os-Lok is your superior alternative to Swagelok fittings & Parker A-lok. Similar to Parker Instrumentation fittings, Os-Lok 904L Tube Fittings work reliably on both seamless and welded-redrawn, fully annealed SA 213 TP304, SA 213 TP316 and SA 213 TP316L Tubing.
