Polietilenska cijev visoke gustine u sistemu za navodnjavanje

Polietilenska cijev visoke gustine Introduction

High Density Polyethylene Pipes are components designed for joining, upravljanje, grananje ili zaptivanje polietilenskih cijevnih sistema, proizveden od polietilena visoke gustine (HDPE) ili polietilen srednje gustine (MDPE), savršeno kompatibilan sa PE cijevima i široko se koristi u području transporta fluida.

Polietilenska cijev visoke gustine Prednost

1. Jaka otpornost na koroziju: otpornost na kiseline i alkalije, slani sprej i erozija hemijskog medija, životni vek duži od 50 godine.

2. Fleksibilna otpornost na udarce: prilagođavaju se slijeganju tla i niskim temperaturama, smanjiti rizik od eksplozije cijevi.

3. Lagan i jednostavan za ugradnju: težina je samo 1/8 fitinga za metalne cijevi, podržava različite metode povezivanja kao što su vrući i električni topi.

4. Zaštita životne sredine i netoksičan: u skladu sa sanitarnim standardima pitke vode (kao što je GB/T 17219), nema padavina teških metala.

5. Niski troškovi održavanja: unutrašnji zid je gladak, otpor trenja je mali, a dugotrajnu upotrebu nije lako skalirati.

Plugging class: End cap, Socket

Repair class: Rush repair section, Saddle bypass

Zaptivke: Brtve su poput prstenova koji se koriste za brtvljenje spojeva između cijevi. Dolaze u različitim materijalima i oblicima ovisno o vrsti veze koju imate.

Pipe Elbows: Koljena cijevi pomažu u promjeni smjera toka cijevi. Dolaze pod uglovima od 90 stepeni i 45 stepeni, a postoje dvije vrste: dug radijus (koji je glatkiji) i kratkog radijusa (koji zauzima manje prostora, ali uzrokuje veći pritisak).

Pipe Bend: Krivine cijevi su poput blagih krivina u cijevi. Koriste se kada vam je potrebna glatka promjena smjera kako biste izbjegli povećanje pritiska. Dolaze u različitim veličinama, like 3D and 5D, which refer to the curve’s length.

Pipe Tee: A pipe tee looks like the letter “T” and is used to split the flow of fluid from the main pipeline. There are different types, like straight tees (which have the same diameter), reducing tees (which have smaller branches), barred tees (used in special pipelines), and wye tees (which connect pipes at a 45-degree angle to reduce friction).

Cross: A cross looks like a plus sign and has one inlet and three outlets. It’s mainly used in fire sprinkler systems, not regular plumbing.

Pipe Reducers: Pipe reducers make a pipe narrower. There are two types: concentric and eccentric. Concentric ones keep the middle of the pipe at the same height. They’re used when two different pipe sizes need to be the same in the middle of a system. Eccentric ones help keep the bottom of the pipe at a certain level, so the outside surface of the pipe stays level.

Pipe Caps: At the end of a plumbing system, there’s a cap. It covers the end of the pipe to stop leaks.

Stub Ends: Stub ends do the same thing as pipe caps but are used with lap joint flanges.

Piping Unions: These are used for pipes with low pressure that need to be taken apart often. They have three parts: a female end, a male end, and a nut. The nut, along with the female and male ends, creates a strong seal.

Pipe Coupling: There are three types: full, half, and reducing. Full couplings connect small pipes. Half couplings connect a small pipe to a large one. Reducing couplings connect two pipes of different sizes.

High Density Polyethylene Pipe FAQ

Q1: How to choose the suitable PE pipe fittings specifications?

A: Korak 1: Confirm the pipe outer diameter (npr. DE110) and SDR value (npr. SDR11).

Korak 2: Select PN rating according to system pressure (npr. PN16 corresponds to 1.6MPa).

Korak 3: Select the material according to the characteristics of the medium (gas requires yellow special parts).

Q2: What are the operation points of hot melt connection?

A: Clean the pipe end to ensure that there is no oil;

Temperature of heating plate is controlled at 210±10℃;

Keep the butt pressure stage stable, do not move during cooling.

Q3: Can PE pipe fittings be mixed with PVC pipe?

A:Direct connection is not recommended. It needs to be connected through a PE/PVC adapter and mechanically sealed with a flange or thread.

Q4: Do pipe fittings support custom non-standard dimensions?

A: Da. Provide 3D scanning mapping services, can customize DN50-DN2000 shaped parts, lead time of 15-30 dana.
