Petrochemical Sampling Systems & Tank Safety Equipment

Wanan Technology manufactures a comprehensive range of petrochemical sampling systems, tank safety valves, and flame arrestors for oil refineries, chemical plants, and storage terminals worldwide. Our product catalog covers seven core categories — from closed loop sampling systems that eliminate vapor emissions during sample extraction, to pressure vacuum relief valves that protect atmospheric storage tanks from overpressure and vacuum collapse. Every product is engineered to meet API, ISO, ASME, and ATEX standards, with material certifications traceable to EN 10204 3.1.

With over 15 years of manufacturing experience and installations across 30+ countries, Wanan Technology is a trusted supplier to Sinopec, ExxonMobil, BASF, Lukoil, and other major operators. Our ISO 9001 quality management system and ASME U-stamp pressure vessel certification ensure that every sampling system, relief valve, and flame arrestor meets the most demanding process safety requirements.

Product Categories

Sistemas de amostragem

Closed loop sampling systems for liquid and gas process streams. Zero-emission design returns purge fluid to the process line, meeting EPA and OSHA vapor-control requirements. Available in 316L stainless steel, Hastelloy C276, and Duplex SS for corrosive service. ASME U-stamp certified sample cylinders with integrated cooling and self-resetting closure valves.

Supressores de chamas

Deflagration and detonation flame arrestors certified to ISO 16852 and ATEX Directive 2014/34/EU. End-of-line and in-line configurations for storage tank vent pipes, vapor recovery systems, and process pipelines. Crimped ribbon element design quenches flame fronts while maintaining low pressure drop. Available in carbon steel, stainless steel, and special alloys.

Válvulas de alívio de pressão e vácuo

Pressure vacuum breather valves (PVRV) for atmospheric and low-pressure storage tanks per API 2000. Spring-loaded and weight-loaded designs protect against overpressure and vacuum conditions caused by filling, emptying, and thermal breathing. Flame arrestor integrated options available. Sizes from 2-inch to 12-inch with ANSI 150# flanged connections.

Válvulas de alívio de emergência

Emergency pressure relief valves for storage tanks and process vessels. Pilot-operated and spring-loaded designs handle large flow rates during fire exposure or abnormal process conditions. Manufactured to API 2000 sizing requirements with set pressures from 0.5 psig to 15 psig. Fire-tested and tamper-proof options available.

Conexões de amostragem

Sampling valves, needles, and fittings for process sample extraction points. Single and double block configurations with purge connections. Needle valves in 316SS and Hastelloy for high-pressure and corrosive service. Compatible with closed loop sampling systems and standard sample containers.

Cilindros de amostra

Stainless steel sample cylinders and sample bombs for liquid and gas sampling. ASME U-stamp and SEB certified pressure vessels from 150ml to 4L capacity. Working pressures up to 3000 psig. Available with quick-connect fittings, rupture discs, and carrying handles for field sampling applications.

Unidades de sucção flutuantes

Floating suction units for storage tanks handling clean products. Designed to draw from the cleanest product layer near the liquid surface, reducing water and sediment entrainment. Available in carbon steel and stainless steel for tank diameters from 10 to 100 meters. Swivel joint and float designs ensure reliable operation across varying liquid levels.
