انسیلاتور پلی اتیلن (HDPE)
در محل هایی که لوله انتقال گاز می‌بایست از زیر معبر یا   سازه ای که دارای بارگذاری متحرک یا ناپیوسته است عبور کند (مانند جاده،ریل قطار و ...) ابتدا لوله ای به عنوان محافظ از زیر معبر بصورت تونلی جاگذاری می‌شود سپس لوله حامل گاز به ‌وسیله پوشش‌های انسیلاتوری که دور آن پیچیده شده محافظت می‌گردد و از میان لوله محافظ عبور داده می‌شود. این عمل با سه هدف صورت می‌گیرد:
1. حفاظت کاتدی:
مقاومت دی‌الکتریکی عالی انسیلاتور و جذب رطوبت کم‌تر از 1% باعث می‌شود حفاظت کاتدیک به خوبی صورت گیرد.
2.حفاظت پوششی:‌
مقاومت بالا نسبت به ضربه و کشش و هم چنین مقاومت عالی در برابر سایش در انسیلاتورهای HDPE موجب می‌شود که از آسیب به روکش لوله گاز در هنگام جاگذاری در لوله محافظ جلوگیری می‌شود.
3.مرکزدهی لوله حامل:
پایه های انسیلاتور موجب می‌شود لوله‌های حامل در کل لوله محافظ در مرکز قرار بگیرند. بدین ترتیب از زنگ‌زدگی و واکنش‌های شیمیایی پوشش لوله در اثر تماس به‌وجود می‌آیند جلوگیری می‌شود.
انسیلاتورهای تولیدی با استاندارد IGS:M-TP-015 و PLD-110 مطابقت کامل داشته و به لطف بهره گیری از نانوکامپوزیت های بهینه شده عملکردی به مراتب مطلوب تر از استاندارد دارند.

PE INSULATOR (Polyethylene)

PRODUCT BRIEF
Pipeline Casing Insulator is a patented series of polyethylene insulators that are universally applicable in the installation of pipelines when the carrier pipe runs inside a casing.They are used to support the coated pipe within a tubular casing,to electrically insulate the pipe  from the tubular casing and to prevent damage to the coated surface of the pipe when the pipe is installed within the casing. With excellent dielectric resistance and low moisture absorption for minimal electric current loss and no impairment of cathodic protection, polyethylene spacers and insulators are an economical choice for use on all plastic pipe, metal pipe up to 60" in diameter and smaller ductile pipe.
Polyethylene casing spacers and insulators aremanufactured by injection molding using polyethylene, which provides high impact strength and a low coefficient of friction.
Two halves are used to construct the 1" through 12" spacers while 14" and above are multi-segmented. Runner height for polyethylene spacers can be increased to provide clearance for bell and spigot connections. Ideal for most sizes of schedule 40 and schedule 80 PVC, C 900, SDR 21 & 26, Ultra-Rib and more, they are only recommended for use on 12” and smaller ductile iron pipe.
Polyethylene casing insulators are recommended for every 6 to 8 feet of pipeline. Molded  into the inner surface of the casing insulators are grooves which prevent slippage of any carrier pipe coating. Lightweight, economical and easy to install, Polyethylene Casing Insulators require only a screwdriver for installation. Do not exceed 35 in-lbs of torque. Sizes are available  from 1" through 60" with a standard runner height of 1". Casing Insulators  from 1" through 12" are constructed of two halves, 2 PI and 4 PI sections make
up 14" and above.


SCOPE OF APPLICATION
When the pipeline is buried in the ground, for instance, at underground road, river, railway and highway crossings, the pipeline is generally further protected by being enclosed within a tubular casing. The pipeline is supported within the casing by a Pipeline Casing Insulator.
The Pipeline Casing Insulator, in addition to its supportive function, electrically insulates the pipeline  from the casing. This insulative function is necessary for he cathodic protection of the pipeline, and also, for preventing electric current loss when the pipeline is used as a conduit for electrical cables. Furthermore, the Casing Insulator prevents damage to the outer coated surface of the pipeline when the pipeline is drawn through the casing during installation.
Economical,high density polyethylene casing Insulators or Spacers provide positive Insulation,high abrasion resistance and low coefficient of friction.High density (linear), injection molded virgin polyethylene casing Insulators/spacers provide positive insulation, high abrasion resistance and low coefficient of friction for a wide variety of energy industry double containment carrier/ casing pipe applications. They are extremely light in weight and easy to handle during installation. A ribbed inner surface prevents slippage and guards against carrier pipe coating damage while the outer surface may include any one of several molded runners to accommodate 2” (50.8mm) x 4” (101.6mm) or larger carrier/casing differentials.

GENERAL FEATURES
Easy Installation: Minimal coefficient of friction of the polyethylene material allows the carrier pipe to be more easily pulled through the casing thus helping in easy installation of the carrier pipe within the casing.
Cathodic Protection: Insulating properties  like excellent dielectric resistance and low moisture absorption of the polyethylene material used ensures of meting with all the requirements of cathodic protection and yielding minimal electric current loss.
Coating Protection: High impact strength and excellent abrasion resistance of the polyethylene material prevents damage to the coated surface of the pipe when the pipe is installed within the casing and ensures long time resistance  from chemical corrode minimizing cold flow of the coating on the carrier pipe.
