Pipes & ducts are manufactured using the "dual helix" filament winding process on computer controlled machines. By adjusting the relative speed of mandrel rotation and glass distribution head movement, helical reinforced layers with different angles can be wound. In order to increase the pipe stiffness, especially on large diameter pipes, silica sand can be added to parallel layers of wall.
Nominal diameter
Nominal size of pipe and fitting is based on internal diameter. The range of available sizes is 25 to 3000 mm.
Nominal pressure classes:
Pipes and fittings are classified according to nominal pressure. Standard pressure classes are 4, 6, 10, 16, 20 and 25 bars. Intermediate or higher-pressure classes are considered on request or depending on the design parameters and conditions
Nominal lengths
Pipes have a length of six meters up to nd150 and 12 meters for bigger diameters.
Fittings
A wide range of fittings as elbows, reducers, tees, caps, flanges etc. Is available.
Fittings are manufactured by the hand lay-up, contact molding and spray-up process. In hand lay-up and contact molding processes veil and alternate layers of mat and woven roving saturated with resin are applied on the mold. In spray-up process continuous strand roving is fed through a chopper gun, combined with catalyzed resin, and sprayed onto the mould surface
Prefabrication spools
Prefabricated spools save installation time as well as costs, freeing the designer from being limited to standard fittings and allowing junction sizes shapes to be specified and manufactured as a better alternative to a complex series of joints.
Pipe fittings are the general names of parts and components that play the role of connection, control, direction change, diversion, sealing and support in the pipeline system. Steel fittings are pressure fittings. According to the different processing technology, it is divided into four categories, namely, butt welding pipe fittings (divided into weld and no weld), socket welding and threaded pipe fittings, flange pipe fittings.
According to the application:
1. pipe fittings for connecting pipes are: flanges, live joints, pipe hoops, clamps, clamps, throat hoops, etc.
2. changing the direction of the pipe: bends, bends.
3. pipe fittings changing pipe diameter: variable diameter (different diameter pipe), different diameter elbow, branch pipe table, reinforcing pipe.
4. pipe fittings with additional piping branches: three links, four links.
5. pipe fittings for pipe sealing: gasket, raw material belt, thread, flange blind plate, pipe plug, blind plate, head, welding plug.
6. pipe fittings for pipe fixing: clasp, hook, ring, bracket, bracket, pipe clamp, etc.
According to the connection :1, welded pipe fittings 2, threaded pipe fittings 3, clamping pipe fittings 4, clamping pipe fittings 5, socket pipe fittings 6, rubber ring connection pipe fittings
According to the material divided into 1, cast steel pipe fittings 2, forged steel pipe fittings 3, alloy pipe fittings 4, stainless steel pipe fittings.
Pipe fittings are widely used in municipal, petrochemical, west-to-east gas transmission, ships and nuclear power.

Unwashed. But clean. No dust, no oil.
Sizes are 0.5 inch to 1.5 inch
PE4710 and PE100 are both grades of high-density polyethylene (HDPE), but PE4710 is derived from PE100 and offers higher performance, particularlyin pressure applications. PE100 has similar or lower physical property requirements than PE4710, while PE4710 has stricter design factors andadditional performance requirements.
Key Differences:
Performance Requirements: PE4710 has higher performance requirementsincluding better resistance to slow crack growth (SCG) and rapid crackpropagation (RCP) compared to PE100.
Packing: Jumbo bags

Conventional tanks (concrete or mild steel) are prone to aging, wear and corrosion.
Concrete can crack when exposed to erosion and natural disasters, leading to water
contamination and leakage â?? and usually canâ??t be repaired. MS rusts easily and its also
easy heat conductor.
FRP â?? Fiber Reinforced Polymer is a strong but light weight glass fiber reinforced plastic
composite used in the aerospace, automotive, marine and construction industries. It has
a high-strength to weight ratio, an extremely long lifespan, and easy to maintain as well as
heat resistant.
FRP sectional panel tanks provides all types of advantages which other liquid storage
methods doesnâ??t. These tanks are DURABLE, LEAK-FREE, COST-EFFECTIVE OVER LIFECYCLE as well as EASY TO INSTALL, RECONFIGURE AND RELOCATE. This is an ideal option
for a wide range of usage including potable water storage, food and factory production,
commercial mining, fire protection, industrial liquids, rainwater harvesting, seawater
storage, and any other kind of liquid and granular storages.
* K-SILICATE is used for jointing Acid Resisting brick in construction of vessels in suited for construction of fume chambers and stacks handling hot, dry Acid fumes and vapors.
It is also used for jointing chemical resisting stoneware pipes.
K-SILICATE cement is good bedding material for Acid â?? Resisting bricks and tiles.
The concrete surface needed protection should be dryed, clean and rough.
The bricks or tiles will be set with K-SILICATE cement over concrete surface applied with a suitable an impermeable interliner.
When Bedding and Jointing Materials are the same.
On the treated surface bricks or tiles are bedded to a thickness of about 6 mm and tamp gently with a wooden piece till the paste squeezes out of joints.
The paste that is squeezed out of the joint should be removed by trowel with good finishing. After the mortar of the joint is dryed treat the joints with 20% Hydrochloric Acid Solution by means of brush. A.R.lining should be always in contact with Acid and not with water.
Concrete subtract like Floor, Wall, tanks and similar surface should be protected with a membrane of Bitrok Mastic or compound steel tanks should be protected with rubber or PVC subjected to chemical conditions and temperature of chemical media. The Brick lining is recommended over the protective layer of Bitrok Mastic.
When Bedding and Jointing Materials are Different.
Spread the silicate type mortar about 6 to 8 mm thick on the back of the tile or brick. Press the tile on the bed leaving required space for joints between tiles for bricks. After the bedding mortar is set, fill Mp the joints with specified cement.PRODUCT DATA SHEET FOR SK-HB ( K-SILICATE) MORTAR
A general purpose cement for acid conditions Resistant to High & medium concentrations of most of the common organic and inorganic acids except Hydroflouric acid. Recommended where the concentration of the acid is high suitable for high temperature. Unsuited to aqueous solutions, alkaline conditions.
PREPARATIONS OF MORTAR :
* Measure 1 part by weight of K-SILICATE solution into a suitable mixing pan.
* Add slowly and gradually 3 parts by weight K-SILICATE mortar and mix thoroughly to form a smooth mortar.
* In hot season very large batches of mortar will become stiff quite rapidly therefore small batches, not exceeding 4 to 8 kgs. Will be prepared.
* The cement mortar will be used before it starts setting.
