Trailer Pengangkut Pipa Besi Hantam Belasan Pohon

Sebuah kendaraan berjenis truk trailer tergelincir dan menghantam belasan pohon yang ada di pinggir ruas Jalan Sudirman, Batam, Kepulauan Riau. Kecelakaan ini diduga disebabkan karena sopir mengendarai trailer dengan kecepatan tinggi.

Trailer pengangkut puluhan pipa baja milik PT Persero Batam ini diketahui hendak menuju Pelabuhan Batu Ampar, Batam. Trailer yang dikendarai oleh Setio tersebut baru saja berangkat dari Kabil, Nongsa, Batam.

Menurut pengakuan Setio, sebelumnya dia mengendarai trailer tersebut
dengan kecepatan cukup tinggi untuk menaiki jalan tanjakan. Namun tak disangka, saat turunan terdapat antrean kendaraan yang menunggu traffic light berganti lampu. Karena panik trailer yang dikendarainya hampir menabrak kendaraan lain, Setio banting setir keluar dari badan jalan dan menghantam belasan pohon.

Proyek Pipa Limbah di Cina Dibatalkan

Pemerintah Cina mengatakan rencana proyek pembangunan jaringan pipa air limbah di kota Qidong dibatalkan setelah ribuan warga memprotes proyek tersebut.

Kantor berita resmi Cina Xinhua melaporkan ribuan warga Qidong, dekat Shanghai, memenuhi jalan-jalan untuk menentang pembangunan pipa pembuangan limbah karena khawatir akan menimbulkan polusi, tetapi mereka membubarkan diri setelah mendengar pengumuman pemerintah pada Sabtu, 28 Juli.

Zhang Guohua, Walikota Nantong, mengatakan pemerintah akan membatalkan jaringan pipa pembuangan limbah yang semula direncanakan untuk menyalurkan limbah dari sebuah pabrik milik Jepang ke laut melalui kota Qidong.

Pembangunan jaringan pipa merupakan bagian dari proyek pendirian pabrik kertas milik Jepang, Oji Paper Group, di Nantong. Sejauh ini pemerihtah tidak menjelaskan apakah rencana pembangunan pabrik juga dibatalkan.

Oji sebelumnya mengatakan air limbah baru akan dibuang setelah diolah sesuai dengan standar nasional Cina.

“Perlindungan lingkungan merupakan prioritas penting bagi perusahaan kami,” tegas Oji seperti dikutip kantor berita AP.

Ongkos pembangunan
Bagaimanapun para pemrotes tidak mempercayai pernyataan Oji dan menyatakan pembangunan pipa limbah akan menimbulkan polusi air di kawasan pesisir.

“Limbah pabrik sudah bisa dipastikan menimbulkan polusi. Kalau dibuang ke sungai, itu akan mencemari laut, akan berdampak pada lingkungan kita. Kita harus memikirkan masa depan, kita tidak bisa hanya memikirkan keuntungan jutaan dolar yang kemungkinan besar akan masuk ke kantong para pejabat,” kata seorang pengunjuk rasa.

Sebagian pemrotes lainnya tidak percaya dengan janji pemerintah membatalkan proyek.

“Pemerintah mengatakan akan menghentikan proyek, tetapi saya tidak puas. Tak seorang pun puas,” kata seorang pria.

Demonstrasi di Qidong berjalan rusuh. Sebagian dari ribuan pengunjuk rasa mendobrak kantor-kantor pemerintah dan memecahkan komputer. Mereka juga mengobrak-abrik meja dan melempar dokumen ke luar jendela.

Unjuk rasa kali ini merupakan bentuk kemarahan terbaru warga Cina terhadap polusi.

Wartawan BBC di Beijing, Martin Patience, melaporkan pembangunan cepat selama 30 tahun terakhir telah menimbulkan ongkos besar, dampak buruk terhadap lingkungan. Tetapi warga semakin vokal menyuarakan penentangan terhadap proyek-proyek industri.

Ball Valve Trunnion & Floating

Characteristic
Ball valves come in two basic designs: floating ball and trunnion mounted. Principally designed as an on/ off isolation valve for a very wide range of temperatures and pressures they have inherent quick opening flow characteristics. all ball valves offer compact actuation due to their rotary quarter-turn operation. fire safe versions are available for use in the oil and petrochemical industries.

Specification
Class 150# , 300# , 600#
General design : API 600, API 602, API 6D
Standard Ratings: 150LB, 300LB, 600LB, 900LB, 1500LB, 2500LB, JIS 10K, 20K, PN 10, PN 16
Material : ASTM A216 WCB, ASTM A105, ASTM A350-CF8
OVIKO Forged Ball Valve

Features

OVIKO forged ball valve,the forging material can ensure sufficient rigidity and strength under maximum rated operation pressure  without inherent flaw of cast. Enough wall thikness of separate body and adaptation of high strength tie bolts are convenient for valve maintenance and sufficient to bear the stress of pipe.The internal parts of valve are carefully designed and selected to ensure  reliability under all kinds of work condition.

Anti-fire safe design

When the trunnion ball valve be used normally,its sealed by seat and ball surface,seat retainer sealed by O-ring and body,this is soft sealed and reliable sealing.When the seat and O-ring are burnt,the seat retainer and body will be sealed by expanded graphite.Thus act anti-fire safe purpose.

Anti-static device

In order to prevent friction among ball,stem and PTFE that generates static electricity which may light the combustibles and explosives that cause an accident,in this ball valve,static-conduction spring is set between the stem and the ball,the stem and the body.Thus static electricity is conducted to ground and system safety is secured.

Free leakage of body Sealed construction

The connective position of valve body and bonnet is double sealed by gasket and O-ring,on this base,such factors as fire,high temperature,shock and uneven opening or closing of the torque all can’t induce external leakage.

Low torque in operation

The self-lubricated bearings are installed at the friction of stem,resulting in wear resistance,fiexibility of operation and low torque.

Double block&bleed(DBB)

When ball is full open or close position,the transmitter substance in center cavity of body can be released by drainage and emptying devices.In addition,the over loaded pressure in the center cavity of valve can be  released to low pressure end by self relief seat.

Emergency sealing

Compound injection holes are designed and compound injection valves are installed at locations of stem/cap and body support of side valve.When sealing of stem or seat is damaged to induce leakage,the compound can be used to do the second time sealing.A concealed check valve is installed in side of each compound injection valve to prevent compound from out flowing due to the action of transmitter substance.The top of the compound injection valve is the connector for fast connection with compound injection gun.

Extension stem

For the underground installed valve,the stem can be lengthened and for the convenience of operation the corresponding compound injection nozzle and drainage valve can be extended to the top of valve.

Automatic body cavity relief

When the body pressure going up un-normally as the unstable factor,the trunnion ball valve downstream seat will be pushed by unnormal pressure,and the release the un-normally pressure automatically,it doesn’t damage to the sealing of upstream seat.

Various driving types

The top pad of valve designed according to ISO 5211,which is convenient for connection and exchange of various drivers.The common driving types are manual,electrical,pneumatic and pneumatic/hydraulic.
