Testing items and standards of stainless steel pipe fittings
Stainless steel pipe belongs to a pipe fitting of a, it is made of stainless steel material. It contains: stainless steel elbow, stainless steel, stainless steel four-way, so different diameter pipe, stainless steel pipe cap, according to the connection method can be divided into socket type stainless steel pipe fittings, stainless steel threaded pipe fittings, stainless steel flanges, fittings and welding stainless steel pipe fittings. Stainless steel elbow for the turning of the tube; flange for tube and pipe connected parts, connected to the pipe end, stainless steel three-way pipe for three root tube collection place; stainless steel four-way tube is used to four pipe collection place; so different diameter pipe for connecting the two different diameter tubes. Main stainless steel material: 304, 304L, 316|, 316L
Standard test for stainless steel pipe fittings is as follows:
403-1999 EJ/T pressurized water reactor nuclear power plant a loop system of large diameter arc welding stainless steel pipe and pipe fittings technical conditions
E29-600-2009 NF pipe engineering. Stainless steel pipe fittings with 7-1 ISO of thread and standard
Specification for electric arc welding of austenitic stainless steel pipe fittings for 4677-1984 BS delivery
11851-2013 DIN stainless steel pipe fittings for the food and chemical industries.
DIN 11853-3-2011 stainless steel fittings sterile, food and chemical industry. The third part: tubes connected with health tube clip
NB/T 20007.12-2013 pressurized water reactor nuclear power plant with stainless steel. Part 12: filler metal welding of 1, 2, 3 grade butt welding of austenite stainless steel pipe fittings
Stainless steel pipe fittings are all kinds of stainless steel pipe connection parts of the general designation, can be in accordance with the shape, use, connection is divided into different categories. It has the advantages of convenient installation, high performance, durability and so on. It is widely used in the construction and installation of all kinds of pipelines.
Stainless steel pipe can be divided into, stainless steel, stainless steel flange, stainless steel head, stainless steel elbow, stainless steel pipe, stainless steel head.
