1.         What is the life span of uPVC pipes?
            Under proper usage conditions & proper storage away from sunlight the uPVC pipes in India have shown a life span of more than 50 years.

2.         What are the benefits of uPVC pipes?
            Savings on (a) Cost of pipes, (b) Handling time, (c) Power & get more water upto 30%
            (d) Working life of pipes is much more.

3.         How does it affect on the quantity and quality of water?
            Yes, we get more water. Over a period of use, the steel pipes get corroded, rusted & the water quality deteriorates. In Ashirvad pipes since there is no corrosion throughout the depth of Column / Drop / Riser pipe the water quality remains good & fresh forever.

4.         Why only Ashirvad uPVC pipes?
            Ashirvad group, the leading PVC pipe manufacturer in the country since 1975. The first to pioneer & develop the technology to make threaded uPVC Column / Drop / Riser pipes in the world. The company is credited by ISO  9001-2000, accredited by leading quality registrar. It has innovated & developed several new products to suit the farmers & customers requirements and these products are well accepted across the country. Ashirvad is well represented all over the country from North to South & East to West. They have a all India presence with a very well developed distributor, dealer & service network.

5.         Can uPVC pipe's strength be compared to a steel pipe?
            The specific gravity of uPVC is 1.4 - 1.45 gm / cm3 where as that as steel has 8 gm / cm3. Taking the strength of the material into consideration the pipes are optimally designed to make them light without any compromise in its strength requirements.

6.         Can the pipes take load of the pump?
            Ashirvad Column / Drop / Riser pipes are designed to hold several times the weight of entire Column / Drop / Riser filled with water & pump assembly. All the type of pumps of different sizes have been considered and the Ashirvad Column / Drop / Riser pipes are made accordingly in the class of Medium, Crystal, Standard & Heavy.

7.         Up to what depth can the pipes be lowered?
            The pipes may be used after careful selection based on pump delivery head & maximum allowable pressure in the pipes. The depth of the bore well may differ from place to place depending upon the water level in the bore well. Ashirvad offers a range of pipes to suit the customer's requirement of various depths & they have been successfully used for 2” Super Heavy up till 1100 ft. Proper selection of Ashirvad pipes can be made for various depth application after careful study of technical booklet.

8.         Does Column / Drop / Riser pipes need full casing in the bore?
            These pipes give the best service in bore wells which have full casing or bore wells which are free from loose bolders & stones. In such areas where loose bolders & stones are prevalent then full casing or slightly larger bore should be made so that the pump does not get stuck.
            Bore collapse problem occurs in some areas & it can also be tackled by giving full casing pipes. This happens in areas with loose soil & silt. Care should also be taken during drilling of the bore well that it is vertical down without any bend.

9.         What should be the bore size with respect to the Pump outside diameter?
            For bore wells without casing pipe and specially in areas with loose bolders present in the bore, it is suggested that the bore well size should be minimum 2" more than the pump outer diameter. This is to prevent pump stuck up due to small bolders. For bore wells with casing minimum of ½" gap between the Casing internal diameter and pump outer diameter is required.

10.      How to choose from the range of pipes offered?
            Right selection of pipes can be made after consulting technical leaflets on the basis of pump & pipe discharge pressure.

11.      There is variation in thickness of the pipes. Why?
            The pipe thickness of the barrel has been designed by taking the pump weight, water Column / Drop / Riser weight and pump delivery pressure into consideration. The end of the pipes are made thicker so that even after making the threads and removal of material the same barrel thickness remains under the threads so that the strength of pipe can be maintained equal in end & barrel.

12.      Are the pipes breakable?
            The pipes do not break under normal handling conditions.

13.      What happens if a bore collapse?
            The pump & the pipes can be pulled out only in cases where the pump can be pulled out by applying a force within the ultimate breaking strength of the pipe as mentioned in the chart. Normally the strength is adequate. In case of severe bore collapse & bolder problems even steel pipes cannot be retrievable  from the bore.

14.      What about after sales service?
            District level dealers are fully equipped & have trained mechanics for correct installation of pipes. These mechanics are always available for all types of service support.

15.      Is tripod required for lowering?
            Yes, tripod is required specifically for use of Column / Drop / Riser pipes in the installation of V6 & V8 pump sets, considering the heavy load requirements. However it is important to note that handling of uPVC pipes is much simpler in comparison to steel pipes.

16.      How to tighten the pipes?
            The pipe is tightened on the principle of screw system. Tighten the pipe with hand  & rope (holding the coupler) so that the rubber seal fully enters in to the coupling pipe. Total description of fitment is provided in company installation booklet.

17.      Any adhesives required during joining of pipes?
            No solvent or adhesive required.

18.      Do we need extra rope to hold the pipes?
            No rope is required. Pipe has adequate strength.

19.      Can we cut the pipes?
            No, pipes cannot be cut for short length requirement. Special request has to be made to the company. The company does however stock shorter length of 1.5 M of few standard running sizes, which can be made available on demand.

20.      Can we re-thread the pipes?
            Under normal use, re-threading of pipe will not be required. Special threads cannot be made at site.

21.      Can metal pipe join with uPVC pipe?
            Metal pipe can be connected with the uPVC only with use of APPL marked adaptors.

22.      Can we use any other metal adapters?
            The quality of APPL marked adaptors are carefully checked in the lab for  (a)  Value of hardness, (b) Quality of casting, (c) Blow holes and other casting defects, (d) Sufficient thickness & (e) Properly designed threads.
            Hence, it is suggested that only APPL marked accessories supplied by ashirvad should be used.

23.      Why to use pump guard?
            Areas with excessive sand pumping or defective unbalanced pump results in excessive vibration in the bottom which may lead to pipe breakage near the adaptor. Pump guard has been designed to be used in these type of areas & problems so that even after breakage of Column / Drop / Riser pipes the pumps can be easily retrievable.

24.      How to select a top adaptor?
            Top adaptors with flange are generally used in deep bore wells so that the flange on top may be used as a support to hold the Column / Drop / Riser . With even higher depths & bigger pump assembly, top adaptor flange type with double coupling length may be used so that two pipe clamps may be used on top to support the Column / Drop / Riser load. For low depth bore well top adaptor without flange may also be used.

25.      Why only Ashirvad Column / Drop / Riser pipes?
            Only Ashirvad has the correct knowledge & understands the requirements for the development of uPVC Column / Drop / Riser pipes. This product has been designed & developed after considerable R&D and more than 30 years of expertise by the APPL team. All other manufacturer who are trying to copy the product do not understand the basics and the technicality of the design which may lead to severe failure & problems for the customer in the long run. Since, this is an engineered product other uPVC pipe manufacturer may not have the capability for meeting the desired design specification required in Column / Drop / Riser Pipes.

26.      What makes Ashirvad "Always First. Always Best"?
            Ashirvad has more than 30 years of expertise in the field of PVC pipe processing. The team of Ashirvad comprises of fully dedicated Engineering department to cater to the engineering needs of the product. This product has been conceived, designed, developed & marketed for the first time by APPL in the world. Ashirvad understands the customer requirements and converts them into products, which have proven track record & mass acceptance all over the country.
