What is the required length of a stub end for an MSS SP-44 flange?
The Manufacturers Standardization Society (MSS) standard covers steel flanges for different pressures and temperatures. Our company is a noted MSS SP 44 series A flange supplier in UAE and closely follows materials, dimensions, tolerance, and testing guidelines.
Stub ends match the pipe material and make tight flanged connections in the place of buttweld fittings. We can provide short and long-pattern stubs in sizes up to 80” or customised to user needs.
What are the advantages of using an MSS SP 44 series A flange?
Under this specification, buyers can procure a weld neck, slip-on, blind, or lap joint flange. MSS SP-44 steel pipe line flanges are easy to weld and repair and have good yield strength from 36-80 ksi (F36-F80).
Another core benefit is machinability. Customers can choose bolt holes, with manufacturers accommodating demands via CNC machining.
How do you select the appropriate coating for an MSS SP 44 series B flange?
Buyers may specify desired coatings for an MSS SP 44 series B flange based on corrosion resistance and temperature tolerance. The typical options include galvanised and zinc plating. Painting (oil black, anti-rust) is also possible for an MSS SP-44 series B blind flange.

What is the recommended torque specification for bolts in the MSS SP 44 class 150 flanges assembly?
The dimensional tolerance of a MSS SP-44 grade F52 slip on flange corresponds to ASME B16.5 (NPS 10). The torque specification states that the tightening clamp load is more than 75% of the proof load on MSS SP-44 class 150 flanges. S wrench can ensure torque-tight performance.
Heat treatments, like normalisation, tempering, etc., on ASME B16.47 series A (MSS SP-44) flanges can bolster mechanical properties.
How are MSS SP-44 steel pipe line flanges tested and certified for various applications?
This standard specifies test methods per ASTM A370. The PSL (Product Specification Level 1 or 2, with supplementary requirements) is also essential.
An important marking is the chemical composition of an MSS SP 44 welding neck flange (killed steel), especially the carbon content (~0.30%). However, impact testing is not mandatory for components under F42.
How do you test ASME B16.47 series A (MSS SP-44) flanges for leaks after installation?
MSS SP-44 - MSS large diameter flanges extend from pressure classes 150 to 900. We advise looking for alignment and surface defects. Conducting hydrostatic leakage testing is recommended.
