What are the common manufacturing problems encountered with an ST37.2 Steel flange?
This unique steel piping component has 0.20% carbon and works admirably in construction and machining. Our role as a coveted DIN 86044 ST37-2 blind flange supplier in UAE involves avoiding manufacturing problems like poor compliance, low quality, dimensional inaccuracy, or improper materials.
Buyers can also experience delayed delivery and a lack of non-standard ST37-2 pipe flanges.
How does the weight of a DIN 86044 ST37-2 blind flange impact the overall cost?
These flanges have lower pressure ratings and hardness but are ductile and mouldable. The weight of ST 37.2 blind flanges depends on the nominal pipe size, diameters (inner and outer), and bolt holes.
As the temperature and pressure endurance of a DIN 17100 ST37 2 flange rise, the schedule, weight, and costs also tend to increase.
Which coatings are available for ST37 flanges?
The usual coatings for ST37 flanges are zinc plating, anti-rust varnish, and paint. Pre-painting may fulfil aesthetic functions also. Other choices are epoxy, electroplating, and phosphate conversions.

What is the maximum pressure rating for an ST37.2 slip on flange based on schedule?
The pressure-handling ability of an ST37.2 slip on flange is not high, but it can work in everyday water supply and heating. The ratings are from 600 to 1500 lbs, depicting the pressure it withstands as temperatures rise.
Customers must consider the pipe diameter, material, working pressure, and safety factor to find the correct schedule (categorised by diameters).
What is the recommended surface treatment for a Grade ST37-2 weld neck flange?
The weld-neck design lets a Grade ST37-2 weld neck flange handle more pressure. We furnish stock surface finish or perform treatments like sand-blasting, polishing, and painting to improve the performance.
Surface treating must ensure adherence to the desired roughness: Ra 0.8 to 3.2, or as per buyer specifications.
How can DIN 24154 lapped joint flange be protected against corrosion?
A limitation of these flanges is their minimal resistance to corrosion, causing rust when exposed to harsh chemicals, water, etc. Galvanisation (hot or cold dip) or zinc electroplating can protect a DIN 24154 lapped joint flange from corrosion through an oxide layer. Some clients choose anti-rust paint to prolong operational life.
Other anti-corrosion-damage solutions are inspection, cleaning, and application-suited use. The flange material must be able to handle the harsh fluids or gases under question.
