Viega profi-press pipe connect with reliable safety, construction is convenient and quick, is suitable for embedded installation, free maintenance update, economy is relatively superior, etc.
Viega profi-press pipe works will be thin-walled stainless steel tube inserted into the viega profi-press pipe socket, using special conformity of tools within pipe fittings, stainless steel pipe clamp to death
hydraulic fitting manufacturer the conformity of cross section shape is hexagonal, combined with the stainless steel pipe and pipe fittings with o-rings seal between, make its have check leakage, drawing resistance, resistance to vibration and high pressure resistance and other properties. Thus it is direct drinking water system, water system, heating system, steam system, industrial tubing system and industrial air system of a kind of relatively advanced fittings. Suitable for water, oil, gas and other pipeline connection. Manufacturing standards: GB/T19228.12003
Nominal pressure: 1.6 MPa or less
Applicable temperature: - 20 ℃ ~ 110 ℃
Applicable medium: oil, water, gas and other non corrosive or corrosive medium

Piping: 15.88 ~ Φ Φ 108 stainless steel welded steel pipe
Stainless steel pipe now more and more widely used, due to its good corrosion resistance has played a vital role in engineering construction, in the process of production we need a solid solution for stainless steel tube processing, the main purpose is to obtain certain martensite increase the hardness of products, let's look at the solution of the stainless steel tube processing:
(1) when the middle follow after solid solution treatment and then heated to 760 + 15 ℃, insulation 90 min, due to Cr23C6 carbide precipitation from austenite and reduce the carbon in the 904 l austenitic
hydraulic fitting supplier stainless steel pipe and alloy element content, Ms point by cooling to room temperature to 70 ℃ and then get martensite + alpha ferrite + residual austenite, the residual austenite in 510 ℃ ageing followed up.
(2) high temperature adjustment and cryogenic treatment solution first heated to 950 ℃ heat preservation after 90 min, due to the increased Ms points, cooling to room temperature to obtain a small amount of martensite; Then through - 70 ℃ after cold treatment insulation 8 h is a certain amount of martensite can be obtained.
(3) solid solution treatment after cold deformation method, cold deformation at room temperature, 904 l seamless tube formation during cold deformation martensite and the deformation and the number of element of 904 l stainless steel tube.
The above three methods is a common method of stainless steel tube of solid solution treatment hope can bring you help.
