What are the packaging requirements for exporting a BS 4504 PN16 Flange?
These British standard flanges operate in pharmaceuticals, power plants, shipbuilding, and water treatment. Exporting requires careful packaging to avoid damage and infestation. As a prominent BS 4504 PN16 Flange supplier in UAE, we use plywood boxes or pallets, ensuring individual, firm wrapping. It facilitates loading and unloading for larger sizes.
Export requirements mandate a packing list for a BS 4504 threaded flange, a certificate of origin, and associated invoices.
Why should a buyer buy BS 4504 PN10 flange from the UAE instead of China and India?
The UAE prides itself on high-quality flanges for petrochemicals, aerospace, and aviation – free of dripping and leakage.
While a Chinese or Indian BS 4504 flanges can be cheaper, they are often produced rapidly with lower quality. The low-end-flanges market is almost saturated, and buyers must be wary of oversupply.
Which common manufacturing problems are associated with a BS 4504 slip on flange?
These easy-to-install, affordable flanges suit lower criticality. However, a BS 4504 slip on flange can face leakage, corrosion, or defects if proper manufacturing standards are unmet.
A manufacturer with multi-step inspection and integrated inspection can supply a high-quality BS4504 PN16 slip on flange. Our trained team guides customers on product selection and installation.

How does the thickness of a BS4504 PN10 blind flange impact its performance?
These flanges (1/2 to 48”) have a pressure rating of PN16. Increasing the thickness of a BS4504 PN10 blind flange helps it endure pressures, shear absorption, and displacement.
Buyers should specify the thickness considering the diameters (inner, outer), bolt holes, and bolt circles. It impacts the pressure rating, integrity, and costs.
How do you verify the authenticity of the BS 4504 PN64 plate flange manufacturer?
A legit manufacturer must be registered and government-approved, with verifiable capacities for a BS 4504 PN64 plate flanges. We cater to a vast clientele in the petrochemical and petroleum sectors and have a 50000 sq. ft. warehouse in Dubai.
You can ascertain the quality of a BS4504 PN40 flange from the MTC.
What is the role of bolting in a BS 4504 welding neck flange connection?
These high-pressure flanges have a tapered hub for even stress distribution. With the pressure class, the number of bolt holes (and diameters) also increases. Usually, a BS 4504 welding neck flanges has sturdier, thicker bolts than slip-on versions.
