Water pipe material selection
  • one、Water pipe

  • Points to consider:High-quality water supply pipes should be able to withstand vibration and shock、Water hammer and thermal expansion and contraction, etc.,and can withstand the test for a long time,will not leak、not burst;When selecting water supply pipes, it is necessary to focus on whether the pipes will cause damage to human health.。

    PPRTube is mainstream:At present, the widely used home improvement water supply pipes arePPRTube。When purchasing, it is necessary to distinguish between hot and cold water pipes,When purchasing, you can choose all hot water pipes,Cold water pipes also use hot water pipes,However, cold water pipes cannot be used as hot water delivery pipes.。

    High-end users of copper pipes:It occupies a monopoly position in the water supply and drainage system of developed countries or regions。such as Hong Kong,Copper pipes dominate the market70%about,Domestic water systems in residential buildings are required to use copper pipes。The penetration rate of copper pipes in established developed countries such as the United Kingdom is higher。At present, copper pipes are mainly concentrated in high-end users。

  • two、drain pipe

  • (1 4 fitting tube 90 degree brass)Specification:There are various specifications of drainage pipes,usually divided into40mm、50mm、75mm、110mmWait。40mmof is generally used for sink water、Floor drain and balcony water;50mmof is generally used for kitchen drainage;75mmof are generally used in the kitchen、balcony、Total drainage of basins etc.;110mmof are generally used for toilet flushing、exterior wall launching。

    material:Stainless steel:304、306;Copper pipes:all bronze、brass;Composite pipes:Steel-plastic composite、Aluminum-plastic composite、Copper-plastic composite, etc.;carbon steel:hot dip galvanized、Cold galvanized materials, etc.;plastic pipe:ppr/abs/pvc/peother materials。

    Shop:Carbon steel sewer pipes and plastic sewer pipes are low-grade materials,It is also more common to use,Plastics have a shorter lifespan;Copper pipes and composites are mid-range sewer materials;Stainless steel sewer pipes are high-grade materials,But there will be rust,Affect the appearance。

  • (1 4 fitting tube 90 degree brass)three、water pipe fittings

  • (1 4 fitting tube 90 degree brass)Points to consider:When selecting fittings,To choose the fittings that match the water pipes,It is best to choose matching pipe fittings of the same brand and material;When buying pipe fittings,Look at the color first、Whether the gloss is uniform;Check whether the wall thickness of the pipe fittings is uniform,Whether the pipe wall is smooth;Pipe fittings with threads should also pay attention to whether the threads are evenly distributed, etc.。Commonly used water pipe fittings are as follows:

categoryIntroduction
directalso called pass-through、Casing joint,Mainly acts as a straight line connection
TeeDivided into same diameter tee and reducing tee,It is used to connect water pipes in three different directions,Used when a water path is to be drawn from a water pipe
elbowIt's for turning the hose,Because the pipe itself is straight,cannot bend,To change the direction of the water pipe,Can only be achieved with elbows。conventionally divided into45degree and90elbow
winding tubealso called crossing the bridge,When two water pipes intersect in the same plane without butting,In order to ensure the normal use of water pipes,transition with winding,like an arch bridge,Avoid direct intersection of water pipes by plane avoidance
valvethe switch,There are two kinds of ball valve and angle valve,The opening and closing of the two valves is slightly different,but the same
Tube cardalso called wall card,pipe fittings for fixing pipes
capalso called plug,Use it when closing unused water pipes
AdapterIf the original water pipes of the house arePETube,Conversion joints are used when decorating,Because it is basically not used in the home improvement processPETube,One end of the adapter isPEmaterial,one end isPPRmaterial,Can realize the conversion of two materials
raw tapeThe metal interface is prone to loosening,when picking up,Use raw tape to make the interface more airtight,Reduce the chance of leakage
(1 4 fitting tube 90 degree brass)
Circuit Tube Material Selection
  • one、plastic conduit

  • PVCTubeis mainstream:Plastic threading pipes are cheaper due to the price、Easy to construct、No rust and other advantages,It is more commonly used in home improvement circuit renovation。The most common plastic pipes arePVCTube,Its main ingredient is polyvinyl chloride,Additional ingredients are added to enhance its heat resistance,toughness,Extensibility, etc.。

    buy tips:choosePVCWhen threading pipes,Need to pay attention to check the quality of the tube,Make sure that the protective tube does not collapse at a bend,Cracks on impact。First check whether the outer wall of the pipe has the manufacturer's mark and flame retardant mark;also,Can be ignited by fire,Then remove it from the fire,Look30sIs it self-extinguishing;third,Bend the tube90Spend,After bending, see if the appearance is smooth;fourth,Can be hit with a hammer until the tube is deformed,No cracks are qualified for impact test。

  • two、metal conduit

  • application:In addition to the use of flame-retardant plastic pipes to cover the protective wires in the family,Metal wire protection tube is also available(metal conduit)。If there are residential buildings, the power cords are protected by flame retardant plastic pipes,while the phone、Cable TV adopts galvanized metal thin-walled tube(can act as a shield)。The metal protection tube of the telephone and cable TV transmission line does not need to be equipped with jumper wires,The galvanized pipe connected by wire or sleeve can meet the shielding requirements。

    Common metal pipes are galvanized steel pipes,Heat-resistant and pressure-resistant fire-resistant。metal conduit、Galvanized line pipe is only suitable for high-rise buildings,Although the cost is higher,But it is not easy to bend and deform。

    buy tips:When purchasing metal conduit,Pay attention that the tube should not have flattening and cracks,There should be no burrs in the tube,The outer diameter and wall thickness of the steel pipe shall comply with the relevant national standards,If rotten teeth or brittle fracture of the steel pipe occur when the steel pipe is twisted,Indicates that the quality of the steel pipe does not meet the requirements。

Other tube options
  • gas pipe

  • Aluminum plastic pipeMaterial:Now use of hoses are not rubber hoses,But an orange aluminum plastic tube,Also a dedicated indoor gas pipe。The inner and outer layers of the aluminum-plastic tube are special polyethylene materials,Non-toxic and environmentally friendly and the quality is light,That“Canada”The nature is very suitable for applications in home decoration。

    Purchase skills:Owners use aluminum plastic tubes as home gas delivery routes are safe and reliable,But carefully avoid buying inferior aluminum plastic tubes,Because the inferior aluminum plastic tube in the market is collided,It's easy to be bending、Deformation,Even rupture,Threat the lives and property of the owners。

  • Floor heating

  • (1 4 fitting tube 90 degree brass)Material:Several tubes used for the floor heating system are:Peroxide crosslinked polyethylene tube(PE-Xa)、Silane crosslinked polyethylene tube(PE-Xb)、Silicon copolymerized polypropylene tube(PP-R)、Pyrene tube(PB)、Non-crosslinking heat-resistant polyethylene tube(PE-RT)etc。These various pipes have used in engineering practice.,Also have their own advantages and disadvantages,Select the specific situation when selecting the pipe。

    PE-XTube:Good mechanical performance、High temperature resistance and low temperature resistance,Is a better floor heating pipe,But its thermally buried performance is not obvious,Especially after-sales maintenance is very inconvenient;

    PP-RTube:andPE-XCompared,PP-RHigh temperature resistance and mechanical properties、Good thermoplastic,But low temperature resistance is lower;

    (1 4 fitting tube 90 degree brass)PBTube:Superior mechanical performance,But its price is the highest year-on-year;

    PE-RTTube:Is a medium-density polyethylene tube with a mechanical performance stable,Toughness,Hot melt connection and repair,construction、Soldering is convenient。

    So nowPP-RTube andPE-RTMany cases of the floor heating pipe。

(1 4 fitting tube 90 degree brass)Conclusion:Hydropower hidden project is unpackable project,To pass this,First choose a good quality hydropower pipe,I would rather spend less elsewhere,It also ignores the safety and reliability of hidden projects。
