What knowledge of natural gas tee is introduced in the standard of natural gas tee?
1. What are the standards for natural gas tee?
1, the joint material standard of natural gas tee. Tee materials can be divided into metal materials and nonmetal materials. Metal tees include carbon steel, stainless steel and alloy steel. Threaded tee is produced according to Maanshan Iron and Steel Co., Ltd., and the national implementation standard is GB/ 12459-2005. Non-metallic tees include PVC, UPVC, PPR, etc. According to the connection mode, it can be divided into two types: snap connection and threaded connection. According to its shape, it can be divided into t-shaped and herringbone.
2. The joint standard classification of natural gas tee standard: GB/T 12459-2005, GB/T13401-2005; Electrical standard asmeb16.9; Chemical standard SH3408 water standard SH3409-96, sh 3410-96; American standard Hg/T 21635; German standard DL/T695；; Japanese standard sy/t 0510; Russian standard DIN26 15, etc.
Two. Types of natural gas tee
1. Welded tee with same diameter elbow: usually called manifold, cut half of the peripheral wall of the outer arm with two 90 elbows, and then weld the remaining two elbows together to form the same diameter. These three links are shown in figure 18.7.
2. Right-angle tee production: there are two kinds of right angles and diameters. Oxygen-acetylene flame cutting machine is usually used to make two continuous cylindrical paints when cutting.
3. Flat welding tee: the tee has short weld seam, small deformation, pipeline saving and simple processing. The manufacturing method is to open an elliptical hole on the straight pipe, with the short axis of the ellipse equal to 2/3 of the outer diameter of the branch pipe and the long axis equal to the outer diameter of the branch pipe, then heat the pipe walls on both sides of the elliptical hole to about 900℃ and pull out the outer plate.
