Sampling System / Sampling Bomb

Yes, DBB Valves are specifically designed to perform in high-pressure and high-temperature settings, making them well-suited for demanding applications like natural gas transmission, petrochemical processing, and liquid pipeline systems.

Absolutely. DBB Valves are engineered for emergency isolation scenarios, providing dependable double isolation to effectively prevent fluid or gas leakage when rapid, reliable shutdown is essential.

By offering true double isolation along with a bleed mechanism, DBB Valves prevent leakage during maintenance or emergency scenarios, ensuring dependable protection in high-risk, critical service applications.

DBB Valves are manufactured from premium-grade materials certified to BSEN 10204 3.1 or 3.2 standards, ensuring exceptional durability and corrosion resistance for demanding environments such as oil and gas operations.

They deliver significant space and cost efficiencies, minimize leakage paths, simplify spare- parts inventory, ensure full traceability and material certification, and reduce the need for extra structural supports.

By minimizing potential leak paths and conforming to ISO 15848- 1 certification, DBB Valves sharply reduce fugitive emissions, ensuring compliance with stringent environmental and safety regulations.

Their integrated, single- body configuration removes the need for separate valve assemblies to be welded or bolted in series, cutting out extra support structures, shortening installation timelines, and reducing labor expenses.

DBB Valves are widely adopted in upstream, midstream, and downstreamoil & gas operations, petrochemical and chemical processing plants, refineries, power generation facilities, and offshore platforms. Their integrated, single- body construction removes the need to weld or bolt together multiple valves, cutting down on required support structures, accelerating installation, and reducing labor costs

They’re deployed for isolating pressure instruments, providing purge, vent, and drain points, enabling sample and injection ports, and ensuring secure process- flow shut- off—especially when handling hazardous or high- pressure fluids.

A DBB Valve delivers two independent isolation points plus a bleed port to guarantee leak- tight safety. Its single, modular body replaces three separate valves, saving both space and cost.

We offer 2 weeks for fittings and 3 weeks for valve for standard product and reasonable quantity.

once the tube fitting is swaged properly as per the instruction, required the pressure testing is done and if the fitting material is compatible with the fluid and the surrounding environment, then this is fit and forget solution.

Our tube fittings are designed to withstand max pressure of 6000 psig. But here the limiting factor is tube not the fittings upto 6000 psig. We should consider the wall thickness of the tube to derive max pressure rating of the system.

1. Right tube selection 2.Follow the swaging instruction 3.Make sure the tube is burr free at the end, and scratch free especially where the ferrule is going to sit.

We offer, Metal seated ball valve, soft seated ball valve, Gate valve, Globe Valve, Double Block and bleed Valve

we have ASTM F 1387 Mandatory and Supplementary test. ECE R 110 , ISO 15500,BS4368 Part IV

We shall share the list of test facility.but to name some: 1. Pneumatic, 2. Hydro Test, 3 Hydro burst test 4. Impulse test 5. Rotary Test 6. Flexure Fatigue Test 6. High Temperature cycle test 7. Low temp Test 8. Fire Test 9. Salt spray test 10 .Cryo-test 11. Helium Leak Test and many more.

Our Standard pressure rating is 6000, 10000, and 15000 psig

1. Hardness should be less than 80 hrb 2. Final finish Tube should be bright annealed after the final process of pilger or draw. 3. OD should be always positive. Even though the standard allows negative tolerance. 4.Good packing as even a minute scratch could be potential leak point if the ferrules sits on it.

The main function of back ferrule is to hinge and give support to front ferrule which is spring loaded.Now since the back ferrule is case hardened after hinging it gets plastically deformed and does not go back to its original position under high pressure or sudden impulse and hereby gives a solid support to front ferrule.
