Seamless carbon steel elbow seamless steel pipe is pushed into the heating type. Pipe elbow is to change the direction of the pipe in the piping system. 45 ° and 90 ° 180 ° three kind most commonly used, according to project needs, also include 60 °bend and other non-normal angles. Elbow Specifications ...

45 degree bend production engineering requirements to control the radius of curvature. Such as a radius of 1.5D, then the radius of curvature must be within the required tolerance. As most of these pipes for welding, in order to improve the quality of welding, the end of the car into a groove, leaving a certain angle, with a certain side, this...

WPL6 Elbow American standard low-temperature seamless or welded pipe, the corresponding pipe A333 Gr.6 is generally used for low temperature -45 degrees environment. ASTM A420 WPL6 heat treatment at -45 ℃ to do low-temperature impact test, rather than -40 ℃, the impact of the average is greater than 18J. Elbow Specifications ...

ANSI B16.9 welding elbow on the wall thickness of the classification are: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, of which the most STD and SCH40 are two commonly used. Elbow Specifications Nominal Diameter ...

The appearance of the EN10253-1 S235 90 degree elbow fittings must be inspected by inspection. The surface of the pipe must be smooth and free of oxide. Shall not have more than 5 percent of the nominal wall thickness, and the maximum depth of not more than 0.8MM scarring, folding, separation and other obvious defects. Greater than the nominal...

EN 10253 Elbow is the standard for fittings in the European Union, which is marked with 2D / 3D / 5D, equivalent to ANSI1D / 1.5D / 2.5D. The other bend radius and length of the elbow are approximately the same as ANSI B16.9. Elbow Specifications Nominal Diameter ...

The ASME B16.9 standard includes the overall dimensions, tolerances, pressure ratings, test and marking of the butt weld key made by the factory for NPS 1/2 to NPS 48 (DN 15 to DN 1200) ASTM A234 GR.WPB Chemical composition and performance index (standard value) Wt% ≤0.30, Si (Wt%) ≥0.10, Mn (Wt%) 0.29-1.06, P (Wt%) ≤0.05, S (Wt%)...

Stainless steel stamping elbow welding is poor, should pay attention to welding process, heat treatment conditions and the selection of appropriate welding electrodes. Stainless steel stamping elbow hardening after welding large, prone to crack. If the same type of stainless steel stamping elbow welding, must be more than 300 ℃ preheating and...

The main international standards of steel welded elbow are: ASME / ANSI B16.9, GB12459, JIS B2311, DIN 2605, GOST 17375-2001, GOST 30753-2001. Elbow production generally take the push molding, through special elbow Pushing machine, mandrel and heating device to expand diameter and bending molding. ASME Elbow Specifications ...

Stainless steel elbow can be divided according to the angle: 45 degree elbow, 90 degree elbow, 180 degree bend. Practical applications will have 30 °, 60 ° and so on. In accordance with the bending radius can be divided into long radius elbows and short radius elbow. Because of the corrosion resistance of stainless steel, acclaimed in...
