GOST 17375 CT20 Short Radius Elbow

Elbow or elbow, manufacturing methods are divided into push the elbow, elbow and welding elbow elbow, the length of the structure is divided into 1.0D, 1.5D, 2.0D. The current international implementation in this regard There are two specifications that are: Metric and Imperial. For example: 1.5D seamless steel elbow, DN100 OD ¢ 108 and ¢ 114.3, the actual length of the structure L152, DN200 ¢ 219 ¢ 219 and ¢ 216.3, the actual length of the structure L302 (R = 1.0DN): used for the limited size of the occasion, the maximum working pressure should not be more than the same radius of the elbow (R = 1.5DN): In general, (R = nDN): used to ease the erosion of the media at the corner and the kinetic energy, can be used to R = 3DN, 6DN, 10DN, 20DN \ x0d According to the different manufacturing methods are divided into sub- Extrusion elbow and welding miter bend \ x0d push elbow and squeeze elbow: commonly used in medium conditions, more demanding medium and small pipe \ x0d welding Miter be…
