Pipa spiral utamane digunakake kanggo pipa minyak lan gas alam, lan spesifikasi kasebut dituduhake kanthi diameter njaba * kekandelan tembok.Pipa spiral bisa dilas ing sisih siji utawa ing sisih loro.Pipa sing dilas bakal mesthekake yen tes tekanan banyu, kekuatan tensile saka las lan kinerja mlengkung kadhemen memenuhi syarat.
Cara perawatan permukaan:
1. Reresik
Solvents lan emulsions digunakake kanggo ngresiki lumahing baja kanggo mbusak lenga, grease, bledug, smoothing agen lan bahan organik padha, nanging ora bisa mbusak teyeng, skala oksida, flux welding, etc ing lumahing baja, supaya iku mung. digunakake minangka langkah tambahan ing produksi anti-karat.
2. Piranti kanggo mbusak teyeng
Kaping pisanan, gunakake sikat kawat lan alat liyane kanggo nyemir permukaan baja, sing bisa mbusak ukuran oksida sing longgar utawa warped, teyeng, welding slag, lan liya-liyane. tingkat Sa3.
3. Pengawetan
Umume, rong cara kimia lan elektrolisis digunakake kanggo pickling.Anticorrosion pipa mung nggunakake pickling kimia, sing bisa mbusak skala oksida, teyeng, lan lapisan lawas.Kadhangkala bisa digunakake minangka sandblasting lan mbusak karat.Reresik kimia mesthi bisa nggawe tampilan tekan tingkat tartamtu saka karesikan lan roughness, nanging pola jangkar iku cethek, lan iku gampang kanggo rereged kahanan.
4. Semprotan (mbuwang) kanggo mbusak teyeng
Penyemprotan (mbuwang) mbusak teyeng yaiku motor sing nduweni daya dhuwur sing ndadekake bilah nyemprotake (mbuwang) kanthi cepet, saengga grit baja, tembakan baja, bagean kawat wesi, mineral lan abrasive liyane disemprot (dibuwang) ing lumahing pipa baja ing efek saka gaya centrifugal., Ora mung bisa rampung ngilangke teyeng, oksida lan rereget, nanging uga pipa baja bisa tekan roughness rata-rata dibutuhake ing efek saka impact galak lan gesekan saka abrasive.
Sawise nyemprotake (mbuwang) kanggo mbusak teyeng, ora mung efek adsorpsi fisik saka permukaan pipa bisa ditambahi, nanging uga efek adhesion mekanik saka lapisan anti-karat lan permukaan pipa bisa dikuatake.Mulane, semprotan (mbuwang) mbusak karat minangka cara ngilangi karat sing cocog kanggo anticorrosion pipa.Umumé ngandika, dijupuk blasting (pasir) aman teyeng utamané dipigunakaké kanggo perawatan lumahing internal lan njaba saka pipe, lan dijupuk blasting (pasir) aman teyeng digunakake kanggo perawatan lumahing pipe.
Pipa baja spiral standar nasional disebut pipa baja spiral 9711.1, pipa baja spiral 9711.2, klasifikasi bahan: pipa baja spiral 16Mn, pipa baja spiral Q345B, pipa baja spiral L245, pipa baja spiral L360, pipa baja spiral X40-X80, utama tujuan, pipa baja spiral untuk pengolahan limbah, pemurnian air Pipa baja spiral, pipa baja spiral untuk pabrik air, pipa baja spiral untuk perusahaan kimia pembangkit listrik, pipa baja spiral untuk tenaga nuklir, pipa baja spiral untuk menyampaikan cairan yang mudah terbakar, pipa baja spiral untuk ngirimake cairan non-combustible, pipa baja spiral standar nasional, lan standar Kementerian Perminyakan SY/T5037 Pipa Baja spiral.Prodhuk iki nggunakake Strip baja panas-mbalek minangka bahan mentahan, kawangun dening spiral biasa anget mbentuk, lan gandheng dening proses welding busur submerged otomatis.Prodhuk ngleksanakake API SPEC 5L, EN10217, GB / T9711.1, GB / T9711.2 standar.Utamane digunakake ing industri lenga lan gas alam kanggo transportasi cairan combustible lan cairan non-combustible lan struktur baja.
