BIS Certification for STEEL TUBES and PIPES

•  13 Jun, 2020
•  ISI Certification (BIS)

Are you curious to know about the Steel Tubes and Pipes to obtain BIS certification for these products? Let's explore more in detail in this blog.

Why you should apply for the BIS certification?

 As we are aware of the Steel Quality Control Order-2020 order published by the Ministry of Steel, depicting the regulatory compliance requirement for Stainless Steel Tubes and Pipes mandating all kinds of Steel Tubes under the purview of BIS certification. As per the Government of India Regulations, all the Steel Tubes and Pipes manufacturers are liable to have a valid ISI Mark certification as per the Scheme-I (Product Certification) of BIS (Conformity Assessment Rules and Regulations 2018, Schedule-II enacted by the BIS Act 2016).

What are the common Indian Standards applicable to Steel Tubes?

 Below, we have mentioned a list of relevant product names along with the applicable IS numbers. 

Plain Carbon Steel Tubes

• Steel tubes for structural purposes - IS 1161
• Steel Tubes, Tubulars, and Other Wrought Steel Fittings  - IS 1239 Part 1 
• Steel Tubes, Tubulars and Other Steel Fittings (Steel Pipe Fitting - IS 1239 Part 2
• Steel tubes used for water-wells (upto 200 mm dia)  - IS 4270
• Cold Formed Welded Carbon Steel Square and Rectangular Hollow Sections for Mechanical, General Engineering and Decorative Purposes - IS 18573
• Steel tubes for idlers for belt conveyors - IS 9295
• Steel tubes for mechanical and general engineering purposes - IS 3601
• Hollow steel sections for structural use - IS 4923
• Steel Pipes for Water and Sewage - IS 3589

Stainless Steel Tubes and Pipes for General Engineering Purpose

• Stainless Steel seamless pipes and tubes for general Services - IS 17875
• Stainless steel welded pipes and tubes for general service - IS 17876
• Stainless steel tubes for the food and beverage industry - IS 6913

Commonly used Raw Material for Tube & Pipes

• Hot-rolled Steel Strip for Welded Tubes and Pipes for IS 1161, IS 3601, IS 4923, IS 1239 - IS 10748
• Hot rolled steel narrow width strip for welded tubes and pipes - IS 15647

Who can apply for the BIS/ISI mark License of Stainless Steel Tubes & Pipes?

Any firm across the globe can apply for BIS Certificate unless it must possess sufficient machinery to manufacture, suitable equipment to perform the required tests as per IS, and competent quality personnel. Hence, there are 3 basic pillars for any manufacturing unit to hold a BIS license (ISI mark license)
1. Manufacturing Machinery
2. In-house testing laboratory
3. Quality Control In-charge

What should be the Manufacturing Process?

 Any Manufacturing process can be practiced as follows:

 IS 17875 – Seamless (Hot Finished/Cold Finished) 

 IS 17876 – Automated welding process without addition of filler metal 

 IS 6913 – Seamless or Welded 

 IS 1161 – 

 a) Hot finished seamless (HFS);
 b) Cold finished seamless (CDS); and
 c) Electric resistance welded/high-frequency induction welded (ERW/HFIW).

IS 3601 –

 

a) Welded tubes (WT) This includes hot finished welded (HFW) tubes, electric resistance welded or high-frequency induction  welded (ERW or HFIW) tubes, and oxy-acetylene welded (OAW) tubes
 b) Hot finished seamless (HFS) tubes
 c) Cold-drawn seamless (CDS) tubes
 d) Cold drawn electric resistance welded (CEW)

IS 1239 Part 1 -

a) Hot-finished seamless (HFS);
 b) Electric resistance welded (ERW);
 c) High-frequency induction welded (HFIW);
 d) Hot-finished welded (HFW); and
 e) Cold-finished seamless (CDS).

What Raw Material is required to get the BIS License as per IS 17876 (Welded)?

Any Raw Material complying with the chemical composition as mentioned in the Indian Standard IS 17876 for a particular grade can be used in the form of strips. However, it is preferred to use the ISI-marked raw material if you are not having Steel Manufacturing Facility as it would result in the rebate of In-house Spectroscopy for the Chemical Composition test.

What Raw Material is required to get the BIS License as per IS 17875 (Seamless)?

Any Raw Material complying with the chemical composition as mentioned in the Indian Standard IS 17875 for a particular grade can be used in the form of bars/mother hollow. However, it is preferred to use the ISI-marked raw material if you are not having Steel Manufacturing Facility Spectrophotometer along with the CRMs/SRMs as it would result in the rebate of In-house Spectroscopy for Chemical Composition test.

What are the In-house Testing Facilities required to get the BIS License of Stainless Steel Tubes or Pipes for general service?

 Major testing requirements are as follows: 

1. Chemical testing– is required if you are producing steel or Non-ISI marked which can be exempted if procuring ISI-marked raw material.
2. Mechanical testing – Tensile (UTM) and its attachments, hardness tester, etc
3. Dimensional testing –Calipers, Micrometer, measuring tape, etc
4. Hydrostatic testing setup for the whole length of Pipe/Tube
