Lined Pipes And Fittings

Our Ejectors deliver chemicals more safely and with greater precision and reliability than traditional delivery methods. There is no moving parts, ejector system is also a safe system because the injected material is not under pressure. If the water flow stops, injection stops instantly. Simple to use and self-priming, Our ejectors are able to run dry with no problems and because they are made with special lined material & they last longer.

The system uses differential pressure between inlet and outlet ports to create a vacuum, which draws chemicals through the suction port. Internal mixing vanes help ensure even distribution and installations do not require a pump or motor.

• Other required pipe materials such as API pipe, stainless steel or alloy steel pipes would be available to meet service conditions and should be referred to us.

Flange Specifications : Flanges confirming to ANSI / BS10 / DIN or any other international standard will be supplied in Mild steel, Carbon steel, Stainless Steel. Standard flanges are Slip-on type and Lap-joint type flanges and will be provided if requested at the time of making an offer.

PP Liner Specifications : The polymer resin shall meet the STM Standard Specifications and our standard PP liners are unpigmented and natural white color. The colored liners are available if specially requested.

Fitting Availability : Standard fittings include 90°C Elbow, 45°C Elbow, Reducing 90°C Elbow, Equal Tees, Reducing Tees, Instrument Tees, Concentric Reducers, Eccentric Reducers, Laterals and Cross for 1" (25mm NB) through 8"(200 mm NB) diameter.

Non - standard fittings such as double and triple branch tees, other special shapes are available per the customer's requirements.

Testing and Inspection :

• All lined pipe and fittings are subjected to 10-15 KV ( SPARK TESTING) non-destructive electrostatic test which is carried out to detect any defects in the liner such as pin holes, porosity, cracks, etc.
• According to the customer's request, hydrostatic testing will be carried out at room temperature using clean water.
• All lined pipe and fittings are subjected to the visual inspection to detect any defects such as liner surface cracks, deformation, outside paint coating, etc.

Storage and Handling Requirements :

• PP lined fittings shall be stored in a shaded area on wooden supports.
• Wooden or plastic end protectors are used to protect the PP lined sealing faces of flanged fittings. End protectors should stay in place until immediately prior to installation.
• Flange sealing surfaces shall be protected carefully and free from defects to eliminate any leakages when the lined pipe and fittings are assembled at site.
• Avoid dropping or impacting lined pipe and fittings with heavy objects or storing near high traffic areas.
