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 ...

Rectangular steel pipe is divided into straight seam welded rectangular steel pipe and seamless square moment two kinds of specifications models: Square tube: caliber F10 * 10 ---- 100 * 100 --- 300 * 300 --- 600 * 600mm, wall thickness 0.5mm-25mm Rectangular tube: diameter J10 * 15 ----- 150 * 50 ---- 300 * 400-600 * 550mm, wall thickness...

API 5L GRb Lsaw Steel Pipe: It is a spiral seam steel pipe welded by the double-wire double-side submerged arc welding process, which takes the strip coil as the raw material and is often warm extruded. Submerged arc welded pipe features: straight seam welded pipe production process is simple, high production efficiency, low cost, rapid...
