What is the pressure rating of the AS weld-on fitting, oiled carbon steel (24Â° DIN 2353) for L and S series?

The pressure rating for the AS weld-on fitting, oiled carbon steel (24Â° DIN 2353) depends on the series: - L series (light): rated for medium working pressures as defined by DIN 2353 for light series fittings . typically lower than S series and suitable for systems with reduced pressure requirements. - S series (heavy): rated for higher working pressures according to DIN 2353 heavy series specifications . suitable for standard hydraulic system pressures. Exact numeric pressure ratings vary by size (dash/nominal diameter) and must be taken from the DIN 2353 pressure tables or the manufacturerâs datasheet for each size and series. For safe selection and use, consult the DIN 2353 standard or the supplierâs technical documentation to obtain the specific maximum allowable working pressure for the required nominal size in L or S series.

Can AS weld-on fitting, oiled carbon steel (24Â° DIN 2353) be used with stainless steel tubes or only carbon steel?

AS weld-on fitting, oiled carbon steel (24Â° DIN 2353) can be mechanically fitted to stainless steel tubes only if galvanic corrosion and material compatibility are addressed. The fitting itself is carbon steel and will promote galvanic corrosion and differential corrosion at the joint when in contact with stainless steel in corrosive environments. Recommended practices: use insulating measures (non-conductive gaskets, sleeves, or coatings), ensure compatible welding procedures (stainless tube prepping, appropriate filler metal if welding), and consider corrosion protection (painting, inhibitors). For pressurized or corrosive-service systems, prefer matching-material fittings (stainless steel DIN 2353) to avoid long-term corrosion and integrity issues.

Are AS weld-on fitting, oiled carbon steel (24Â° DIN 2353) L and S series compatible with hydraulic fluids and temperatures?

AS weld-on fitting, oiled carbon steel (24Â° DIN 2353) L and S series can be compatible with hydraulic fluids and temperatures, but suitability depends on fluid type, operating temperature range and system pressure. Key considerations: - Material: Oiled carbon steel offers good mechanical strength and is commonly used in hydraulic fittings. It is generally compatible with mineral oils and many petroleum-based hydraulic fluids. - Sealing: 24Â° DIN 2353 fittings rely on metal-to-metal 24Â° cone sealing surfaces (and appropriate O-rings or seals where specified). Compatibility with specific fluids depends also on the seal material used in the system (e.g., nitrile, Viton, etc.). If only metal cone sealing is used, fluid compatibility is mainly determined by carbon steel corrosion resistance with that fluid. - Temperature: Carbon steel retains strength over a wide temperature range but corrodes more rapidly at elevated temperatures and in presence of aggressive fluids. Typical hydraulic mineral oils operate roughly between â20 Â°C and +80 Â°C; carbon steel fittings will perform in that range. For prolonged use above ~100 Â°C or below â40 Â°C, verify material properties and seals. - Series (L vs S): L (light) and S (heavy) indicate wall thickness and pressure rating. S series (heavy) is suitable for higher pressures and harsher conditions; choose series based on system pressure and safety margins. - Corrosion and additives: Water-glycol fluids, phosphate esters, aggressive additives or frequent condensation can accelerate corrosion of carbon steel; in such cases stainless steel or appropriate coatings may be preferable. - Standards and verification: Ensure installation per DIN 2353 recommendations, correct welding procedure for AS weld-on fittings, and verify pressure/temperature ratings from supplier datasheets for the chosen series and sizes. Conclusion: AS weld-on fitting, oiled carbon steel (24Â° DIN 2353) L and S series are generally compatible with common mineral-oil hydraulic fluids and typical hydraulic temperature ranges when correctly selected and installed. For aggressive fluids, extreme temperatures, or corrosive environments, confirm compatibility with the fluid and seals or consider alternative materials.
