When we buy a forged steel ball valve, we have some instructions on how to maintain the valve, such as the placement position and where it is stored. Generally, it is cool and so on. Not only the current forged steel ball valve can work under many high temperature and high pressure due to its stable performance. Because of the stability of the myocardial infarction, the forged steel ball valve is used by a large number of customers. Today we do not have enough description of the forged steel ball valve, let's take a detailed introduction to the repair of the forged steel ball valve for you.
In daily life, the forged steel ball valve is widely used in the big blue product series, and the market consumption is relatively large. Therefore, proper warranty maintenance can not only reduce maintenance time, but also improve work efficiency, thereby saving procurement costs and avoiding The necessary waste.
With a long service life and maintenance-free period, it will depend on several factors: normal working conditions, maintaining a harmonious temperature/pressure ratio, and reasonable corrosion data.
We have a deep understanding of the maintenance of forged steel ball valves. Below we will introduce you to the ball valve. Before using the forged steel ball valve, flush the pipe and the valve body over the flow part with water to prevent residual iron filings. Other debris enters the valve body cavity to ensure proper operation of the valve body.
The forged steel ball valve is used to weld the metal of the sealed cover. If the pipe ball valve is cleaned, it is necessary to focus on preventing damage to the seal ring during the disassembly and causing damage to the valve. If there is a slight leak in the packing during use, you can slightly tighten the stem nut until the leak stops, and you can not continue tightening.
When the forged steel ball valve is closed, some of the medium may remain in the valve body and also bear a certain pressure. Before servicing the ball valve, close the shut-off valve before the ball valve, then open the ball valve that needs to be repaired, and completely release the internal pressure of the valve body. In the case of electric ball valves or pneumatic ball valves, the power supply or air supply must be disconnected first.

Stainless Steel Seamless Square Pipe
Stainless steel square tube is a hollow strip of steel, because the cross section is square so called square tube. A large number of used for conveying fluid pipelines, such as oil, natural gas, water, gas, steam, etc., in addition, in bending, torsion strength at the same time, lighter weight, so it is also widely used in manufacturing machinery parts and engineering structures.Stainless steel square tube classification: square tube is divided into seamless steel tube and welded steel tube (seam pipe) two categories.
According to section shape can be divided into square and rectangular tube, widely used is circular steel tube, but there are some semicircular, hexagonal, equilateral triangle, octagonal and other special-shaped steel tube.For stainless steel square tube under fluid pressure to carry out hydraulic test to test its pressure capacity and quality, under the specified pressure does not leak, wet or expansion for qualified, some steel pipe according to the standard or the requirements of the side of the roll test, flaring test, flattening test.
Square tube specifications :5*5~150*150 mm thickness :0.4~ 6.0mmSquare tube material :304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347H, 310S, etc.The production process is: a. Round steel preparation; B. heating; C. Hot rolling perforation; D. cutting head; E. pickling. F. grinding; G. lubrication; H. Cold rolling; I. degreasing; J. Solution heat treatment; K. straightening; L. in cutting; M. pickling. N. Finished product inspection.
