Yadda Ake Shigar HDPE Gas Bututu Daidai?

Polyethylene (HDPE) bututun gas ya zama kayan da aka zaba don tsarin isar da iskar gas saboda kyakkyawan aiki da tattalin arziki. A matsayinsa na babban mai samar da bututun iskar gas na PE a kasar Sin, ba kawai muna samar da kayayyaki masu inganci waɗanda suka dace da ƙa'idodin ƙasashen duniya ba, amma kuma samar da OEM (masana'anta kayan aiki na asali) da ODM (masana'anta zane na asali) sabis ga abokan cinikinmu don biyan buƙatun daban-daban na kasuwar duniya.

Na farko, Babban fa'idodin HDPE Gas Pipe:

1. Juriya na lalata da tsawon rai

   Kayan PE yana da juriya na halitta ga lalata sinadarai da lalatawar lantarki, musamman dace da rigar, yanayin ƙasa acid-alkali. Idan aka kwatanta da bututun ƙarfe na gargajiya, rayuwar sabis ɗin sa na iya kaiwa fiye da 50 shekaru, kuma ana iya rage farashin kulawa da fiye da haka 60%.

2. Babban sassauci da juriya mai tasiri

Tsawanta a karya bututun PE ya wuce 350%, wanda zai iya tsayayya da nakasar da aka samu ta hanyar kafa tushe ko girgizar kasa. Ayyukan har yanzu barga ne a ƙarƙashin matsanancin zafin jiki na -60 ℃ zuwa 40 ℃.

3. Gini mai nauyi da dacewa

Yawan yawa ne kawai 1/8 na bututun karfe, kuma ana inganta harkokin sufuri da shigarwa sosai. Amfani da narke mai zafi ko fasahar haɗin haɗin lantarki, babu buƙatar hadadden kayan walda, gudun gini ya karu da 30%-50%.

4. Kariyar muhalli da aminci

Babu abubuwa masu cutarwa da ke fitowa a cikin tsarin samarwa, kuma 100% sake yin amfani da su. Bangon ciki na bututun yana da santsi, juriyar kwararar iskar gas kadan ce, kuma hadarin yabo ya yi kadan, wanda ke haɗuwa da EU EN 1555 da China GB 15558 ma'auni.

Na biyu, Tsarin shigarwa na HDPE Gas Pipe

1. Shiri kafin shigarwa

Tsarin tsarawa: Tsara jagorancin bututun bisa ga kwararar iskar gas, matakin matsa lamba (kamar SDR11/SDR17) da yanayin ƙasa, kauce wa cikas a karkashin kasa, kuma tabbatar da cewa zurfin da aka binne shine ≥ 0.8m (hanya) ko ≥ 0.6m (titin gefe).

Karɓar kayan abu: duba bayyanar bututun (babu karce, kumfa), takamaiman takardar shaidar (gami da alamar narkewar albarkatun ƙasa, Rahoton gwajin lokacin shigar da iskar oxygen), da samfurin don gwajin ƙarfin hydrostatic (80℃/165h).

Horon ma'aikata: Ma'aikatan ginin suna buƙatar riƙe takardar shaidar aikin walda bututun PE, ƙware da zafi narke inji sarrafa zafin jiki (220℃±10℃) da sigogi na matsa lamba (zafi sha matsa lamba 0.15MPa, sanyaya matsa lamba 0.02MPa).

2. Tono mahara da kuma maganin tushe

Lokacin da ake amfani da tono na inji, 20cm da hannu tsaftace Layer aka tanada a kasan tare mahara don tabbatar da tushe ne santsi.

Sanya Layer matashin yashi mai kauri 10cm akan dutse ko ƙasa mai ƙarfi don hana fashewar bututu.

3. Sanya bututu da haɗi

A. Zafi mai narkewa (DN≥90mm) :

  1. Niƙa ƙarshen fuska zuwa lebur, yawan rashin daidaituwa < 10% kaurin bango.

  2. The dumama farantin zazzabi aka saita a 210 ℃-230 ℃, kuma ana ƙididdige lokacin dumama bisa ga kauri na bango × 10 seconds / mm.

  3. Ci gaba da matsa lamba a matakin endothermic, lokacin canjawa ≤5 seconds, lokacin sanyaya ≥ bango kauri × 1min/mm.

B.Electric fusion dangane (DN≤315mm) :

  1. Cire Layer oxide kuma yi alama zurfin shigar a sarari.

  2. Saita wutar lantarki (yawanci 36V-48V) bisa ga juriya darajar hannun fuse, and the welding time is automatically calibrated.

Quality inspection: the flanging height should reach 1/3 of the wall thickness of the tube, and the electric melting observation hole should be pushed out.

4. Pressure test and backfill

The strength test (1.5 times the working pressure, 4h pressure regulation) and the tightness test (1.15 times the working pressure, 24h pressure drop ≤1%) are carried out in sections.

Backfill using lamination compaction method, each layer thickness ≤20cm, the initial backfill using fine sand to protect the pipeline.

The scientific installation of Polyethylene (HDPE) Gas Pipe is the core link to ensure gas safety, and choosing a Chinese pipes and fittings manufacturer with leading technology can better obtain the triple advantages of cost, quality and service.
