耐化學腐蝕的PTFE光滑管軟管-919 / 919B / 919J / 919U
Chemical Resistant PTFE Smoothbore Hose - 919/919B/919J/919U
PTFE軟管具有出色的化學相容性,耐濕性,可在較寬的溫度范圍內使用,并且摩擦系數(shù)低,有助于流動。大多數(shù)919軟管可承受的溫度高達450°F。派克的耐化學腐蝕PTFE光滑管軟管具有出色的化學兼容性,可承受高達+ 450°F的溫度。919 / 919B組件可用于多種應用,包括但不限于化學傳輸線,高溫通用液壓系統(tǒng)和冷卻劑線。PTFE芯管具有防潮功能,并且具有任何已知塑料中低的摩擦系數(shù),因此可將壓降和沉積物降至低。PTFE軟管比金屬軟管更不容易因應力或彎曲而破裂。919軟管符合SAE 100R14A,并由符合FDA的天然PTFE管制成,而919B軟管符合SAE 100R14B,并由黑色的耗散PTFE芯管制成。輸送油,油漆,燃料或蒸汽等非導電流體時,應使用Parker 919B。派克(Parker)的919J PTFE軟管具有擠出的硅樹脂護套,可提供清潔,光滑的覆蓋層,而919U則具有無磨損,耐磨的聚氨酯護套,可保護不銹鋼鋼絲增強材料免受磨損,磨損和污染。這兩種軟管均由符合FDA標準的天然PTFE芯管制成,并由304不銹鋼編織層加固。919U軟管上的聚氨酯護套減小了低和高溫度范圍(-40°F至+ 275°F)。919J PTFE軟管上的硅膠套只會降低較低的工作溫度(-40°F至+ 450°F)。這兩種軟管均由符合FDA標準的天然PTFE芯管制成,并由304不銹鋼編織層加固。919U軟管上的聚氨酯護套減小了低和高溫度范圍(-40°F至+ 275°F)。919J PTFE軟管上的硅膠套只會降低較低的工作溫度(-40°F至+ 450°F)。這兩種軟管均由符合FDA標準的天然PTFE芯管制成,并由304不銹鋼編織層加固。919U軟管上的聚氨酯護套減小了低和高溫度范圍(-40°F至+ 275°F)。919J PTFE軟管上的硅膠套只會降低較低的工作溫度(-40°F至+ 450°F)。

Parker's Chemical Resistant PTFE Smoothbore hoses have exceptional chemical compatibility and handle temperatures as high as +450°F. 919/919B assemblies are used in numerous applications including, but not limited to, chemical transfer lines, high temperature general hydraulics, and coolant lines. The PTFE core tube resists moisture and offers the lowest coefficient of friction of any known plastic, therefore minimizing pressure drops and deposits. PTFE hoses are less susceptible to cracking from stress or flexing than metal hoses. The 919 hose meets SAE 100R14A and is constructed of a natural FDA compliant PTFE tube while 919B hose meets SAE 100R14B and is manufactured with a black static-dissipating PTFE core tube. Parker 919B should be used when conveying non-conducting fluids such as oils, paints, fuels, or steam. Parker’s 919J PTFE Hose features an extruded silicone jacket to provide a clean, smooth cover and 919U features a non-marring, abrasion-resistant polyurethane jacket to shield the stainless steel wire reinforcement against wear, fraying and contaminants. Both of these hoses are constructed of a natural FDA compliant PTFE core tube and reinforced with a 304 stainless steel braid. The polyurethane jacket on the 919U hoses reduces the minimum and maximum temperature range (-40°F to +275°F). The silicone jacket on the 919J PTFE hose only reduces the lower operating temperature (-40°F to +450°).

為什么要使用派克919軟管?
耐化學腐蝕的PTFE-聚四氟乙烯光滑管軟管-919 / 919B / 919J / 919U
派克919系列軟管的小壁厚為.030英寸PTFE,可承受苛刻的化學藥品和高溫。工業(yè)界通常使用該軟管,因為它符合SAE或FDA標準,盡管由于PTFE內管具有耐用性和使用壽命,所以有些人只是簡單地使用它。隨著時間的流逝,如果材料的設計不能承受特定的介質,則苛刻的化學藥品和油類基本上會侵蝕內管。一旦內管破裂,流體就可以開始通過金屬加固夾套吞噬。經(jīng)過足夠的時間后,軟管可能會從蓋上吞下。顯然,如果您要處理潛在的環(huán)境和健康危害,那就不好了。
哪種PTFE軟管適合我的應用?
919軟管有4種類型,每種類型各有特點。我們將為您分解它們。
919 / 919B軟管
919 / 919B軟管的工業(yè)用途包括化學藥品,液壓油,壓縮空氣和氣體以及冷卻劑的輸送。919和919B軟管實際上是相同的,除了一個主要區(qū)別。919軟管的內管是符合FDA的天然PTFE材料,而919B型軟管則具有黑色的靜電消散芯管。因此,在輸送非導電介質(如油,油漆,燃料,蒸汽等)時,應使用919B軟管。

與919J軟管相比,該系列軟管提供了更持久的抗磨損和抗污染的外層保護。與有機硅相反,該覆蓋層是無磨損,耐磨的聚氨酯覆蓋層。由于這一特性,如果溫度可能超過275°F,則不適合使用919U軟管。

Parker 919 Hose - Why use Parker 919 Hose?
Parker 919 series hose is constructed with minimum .030″ PTFE tube wall to withstand both harsh chemicals and high temperatures. Industries commonly use this hose because it complies with SAE or FDA standards, although some simply use it because of the durability and longevity the PTFE inner tube provides. Over time, harsh chemicals and oils essentially eat away at the inner tube if the material is not designed to withstand that particular media. Once the inner tube breaks down, the fluid can begin to eat through the metal reinforcement jacket. After enough time goes by, the hose could eat through the cover. Obviously, not good if you’re dealing with potential environmental and health hazards.
Which PTFE hose is right for my application?
There are 4 types of 919 hose, each with their own distinct characteristics. We’ll break them down for you.
919/919B Hose
Parker 919 hoseIndustry uses for 919/919B hose include the transfer of chemicals, hydraulic fluids, compressed air & gas, and coolants. 919 and 919B hose are virtually identical with the exception of one major difference. The inner tube for 919 hose is a natural FDA compliant PTFE material while 919B type hose has a black static-dissipative core tube. For this reason, you should use 919B hose when conveying non-conducting media such as oils, paints, fuels, steam, and so on.
Inner tube: 919 – Natural FDA Compliant PTFE | 919B – Black Static-Dissipative PTFE Reinforcement: 304 stainless steel braid
Operating Parameters

FDA 21 CFR 177.1550 (919 Natural tube)
919J Series Hose
Parker 919J hose with silicone cover919J hose is the better option if an outer layer of protection is important. It has a silicone cover to protect the stainless steel wire reinforcement from fraying. It also prevents external contaminants from entering the transfer line.
Inner tube: 919 – Natural FDA Compliant PTFE Reinforcement: 304 stainless steel braid Cover: Extruded silicone
Operating Parameters
Temperature Range: -40°F (-40°C) to +450°F (232°C)

919U Series Hose
Parker 919U hose for abrasion resistance
series hose provides a more durable outer layer of protection against fraying and contaminants than 919J hose. The cover is a non-marring, abrasion resistant polyurethane cover, as opposed to silicone. Due to this characteristic, 919U hose is not suitable for use if temperatures could exceed 275°F.
