Thin-walled seamless steel elbow, Hebei Runhong (certified), carbon steel seamless elbow

 90 ° elbow buy preferred Hebei Runhong hot! Production process characteristics elbow 90 degrees hot, what does? Let's take a look. First, it does not need the tube as raw materials, saving pipe equipment and tooling costs, and get arbitrarily large diameter and wall thickness of the relatively thin carbon steel elbow. Secondly, the blank plate or developable surface for low-carbon steel seamless elbow specifications, thus cutting carbon steel seamless elbow simple, easy to ensure accuracy, easy assembly and welding. Finally, 90-degree elbow thermocompression treatment for hardening, quenching is heated to a critical temperature above the elbow, holding time, and then quickly into the quenchant, its temperature suddenly decreased, greater than the critical cooling rate rapid cooling rate, and heat treatment to obtain martensite-based imbalance organization. Seamless carbon steel elbow buy preferred Hebei Runhong good quality and low price! Radius of curvature of the product: can be divided into long and short radius bend radius thick walled elbow. Long radius elbow refers to its thick wall radius of curvature equal to 1.5 times the outer diameter of the tube, i.e. R = 1.5D. It refers to the thick short radius bend radius of curvature equal to the outer diameter of large diameter carbon steel seamless pipe elbows offer, namely R = 1.0D. (D is the bend diameter, R is the radius of curvature) thick-walled steel elbow | steel R = 1d elbow. Products: welded, seamless carbon steel seamless elbow 45 ° elbow, butt diameter pipe, seamless tee, cross, flange, and other products production standards: GB12459-90, GB12401-90, ASME / ANSI B16.9, DIN, JIS, ISO and other standards Material: 321,304,304L, 316,316L organization of production, in accordance with the standard user-provided materials for the production of thin-walled seamless steel elbow, Hebei Runhong (certified), carbon steel seamless elbow by Hebei Runhong Pipeline Limited.
