Stainless Steel 304 Pipe Fittings
Stainless Steel 304 Pipe Fittings are used to connect pipes, change the direction of flow, create branch connections, reduce or increase pipe diameter and terminate piping systems.
Grade 304 is one of the most widely used austenitic stainless steel grades because it provides a practical balance of corrosion resistance, strength and fabrication properties.
SS 304 pipe fittings are suitable for many industrial environments and can be supplied in configurations designed for different piping layouts. For applications involving more aggressive chemicals, high chloride exposure or specific process conditions, the material should be evaluated against the operating environment before selection.
Mcneil Instruments supplies SS 304 fittings for customers in India, USA, Nigeria and Turkey, with product specifications selected according to the requirements of each project.
ASTM A403 WP304 Pipe Fittings
ASTM A403 covers wrought austenitic stainless steel pipe fittings intended for pressure piping applications. WP304 refers to fittings manufactured from Type 304 stainless steel under this specification.
ASTM A403 WP304 pipe fittings are commonly specified for industrial piping systems where material quality, dimensional accuracy and reliable connection between piping components are important.
Depending on the fitting type and project specification, dimensional requirements may include standards such as ASME B16.9, ASME B16.28 and MSS SP-43.
Mcneil Instruments supplies ASTM A403 WP304 fittings for industrial projects in India and for international requirements in markets including the USA, Nigeria and Turkey.
Types of Stainless Steel 304 Pipe Fittings
Mcneil Instruments offers different SS 304 pipe fitting configurations for industrial piping systems.
Stainless Steel 304 Elbows
SS 304 elbows are used to change the direction of a piping system. Common configurations include 45-degree and 90-degree elbows. Long-radius and short-radius designs can be selected according to piping requirements.
Stainless Steel 304 Tees
Stainless Steel 304 tees provide branch connections in piping systems. Equal tees connect pipes of the same nominal size, while reducing tees connect a smaller branch to a larger run.
