This specification covers requirements and test methods for high-density polyethylene (PE) materials, pipe and fittings for pressure or non-pressure oil and gas producing applications to convey fluids such as oil, dry or wet gas, multiphase fluids, and non-potable oilfield water. This specification does not cover pipe for gas distribution applications. Plastic tanks have become the preferred choice of the automotive manufacturing companies owing to its various inherent advantages over the metal fuel tanks and is gaining high popularity in the market. These tanks are produced using High-Density Polyethylene (HDPE).
Pune, (GLOBE NEWSWIRE) -- The global automotive fuel tank market size is predicted to reach USD billion by , exhibiting a CAGR of . This book, “A Guide to Polyolefin Blow Molding,” z High density polyethylene (HDPE) z Ethylene copolymers, such as ethylene vinyl acetate (EVA) z Polypropylene and propylene z Automotive items, such as gas tanks, oil bottles and windshield fluid containers, air ducts and seat.
Polyethylene Fitting Catalogue HDPE Fitting Cataloge. Polyethylene pipelines require various PE fittings according to type of application. PE pipes are used in sewage, water supply, fire systems, cable & gas covering, which each pipe fitting is suitably designed as per application demands. The HDPE pipe fittings can be performed in several ways as described below It should be noted that based. This discovery led to the development of a new catalytic process for the making of high-density polyethylene. Now, billions of pounds of polypropylene and high-density polyethylene are used each year in packaging of every shape and size, from milk jugs to large chemical drums; in toys, tools, furniture, and fibers; in water, sewer and gas pipes.

Blow moulded high density polyethylene (HOPE) fuel tanks have superior strength to mass ratio compared with metal equivalents (the density of steel is about kg/m3 compared with HOPE, which has a density of under kg/m3). HOPE will tend to drip in. A new HDPE retail fuel tank was born that would change the way retail stations procure and install tanks in the future.
This fuel tank will have a capacity of 50m3 (50 l) and weigh only tons. This is in comparison to the 40m3 (l) double wall tank weighing more than 7 tons.

The tank shield is plain carbon steel. The steel fuel tank has a volume of 31 gallons while the volume of the HDPE tank is gallons. The HDPE tank weight was normalized to 31 gallons so that the two tanks delivered equivalent functional- ity.
Life Cycle Inventory Size: 30KB. High density Polyethylene (HDPE) tank systems overcome the persistent corrosion problems of stainless steel and mechanical failure of flexible bags.
HDPE, next to being versatile and durable, will ensure an almost condensation free environment for fuel and will provide water clean and free of any undesired taste for the galley. History of Fuel Tank Development 19 JANUARY MIZ Content 1.

Kuraray and EVAL Europe. Kuraray Co., Ltd. has long been a leader in high gas barrier technology and development. The company is the first and foremost producer of EVOH (ethylene vinyl- alcohol copolymer resins) under the name EVAL™ and the manufacturer of KURARISTER™. WEB EXCLUSIVE A patented family of HDPE resins boasts improved resistance to bio-diesel fuels and is poised for use by makers of automotive plastic fuel tanks.
Newly available from Basell North America, Inc., a LyondellBasell company, Wilmington, Del., are Lupolen HDPE grades AG BD for blow molding and A IM BD for injection molding. To solve this problem, HDPE is used nowadays as the main material, and fuel tanks using EVOH for a barrier material and formed by multi-layer blowing are installed in the majority of automobiles conforming to the Tier 1 regulations set by EPA and the LEV I regulations set by CARB.
The Sub-Committee first published “Design Recommendation for Storage Tanks and Their Supports” inand amended it in theand publications. This current revised recommendation provides bulk material pressures for silos As the number of smaller under-ground tanks used for the storage of water and fuel is increasing in.
HDPE (High Density Polyethylene) is defined by a density of greater or equal to g/cm 3. HDPE has a low degree of branching and thus stronger intermolecular forces and tensile strength. HDPE can be produced by chromium/silica catalysts, Ziegler-Natta catalysts or metallocene catalysts. 3 The Linear Polyethylene Family HDPE, MDPE, LLDPE: linear polyethylenes Classification by density – determined by short chain branching through comonomer content Properties Melt index 0,03 - > g/10 min ( C/2,16 kg) Melting point C Polydispersity (TVK grades) Monomodal Bimodal 0, 0, 0, 0, No of SCB LLDPE.
HDPE is really hard to weld. The strongest joint you can make with it is with a epoxy called poly-weld. That is specially made for HDPE and you need to use a torch on the edges before you weld to prepare the plastic to "accept" the epoxy.
I have also been looking into making a tank out of HDPE. Mostly blow moulded or injection moulded multi layers HDPE fuel tanks are quite common. Significant developments have been done by the industry to meet the recent emission standards.
Compared with existing rubber and steel fuel lines, plastic fuel lines are lighter in. Global Vehicle Fuel Tanks Market is anticipated to grow at a higher CAGR as vehicle fuel tanks are storage tanks and a safe container for flammable fluids. Recently, plastic fuel tanks are widely used by automobile industry.
Steel fuel tanks were mostly preferred by automobile industry but the rising popularity of plastic fuel tanks and [ ].
Polyethylene is a whitish, semi-crystalline, and effectively opaque engineering thermoplastic which, chemically, is a very high molecular weight ( million) HDPE.
As a result, its melt viscosity is extremely high and normally can only be processed by powder sintering methods. This discovery led to the development of a new catalytic process for making both polypropylene and high-density polyethylene (HDPE).
Today, these plastics are used in thousands of applications. Polypropylene and HDPE are essential materials in a variety of consumer-product goods such as food packaging and films, coolers, detergent bottles.
Subject: HDPE Fuel Tank • Ethylene homopolymer or copolymer comprising ethylene and not more than 10% by weight of an alpha-olefin having from 3 to 20 carbon atoms • Density of from to g/cm3 [HDPE is defined by a density of greater or equal to g/cc] • Prepared by classic Ziegler-Natta catalysts, i.e.
titanium.HDPE (High Density Polyethylene), part of the polyolefin family of materials, is a semi-crystalline thermoplastic material, with a continuous use temperature range of ° F (° C) to ° F (82° C).
It is categorized as a standard material, and offers high impact strength, high chemical resistance, and very low water absorption.Coextruded plastic fuel tanks containing 27% post consumer recycled material were produced.
The recycled material was high-density polyethylene recovered from end-of-life vehicle fuel tanks. Recovered fuel tanks contain residual fuel inside the tank and absorbed in the tank .
