• Application:

The well test hose is suitable for drill-stem testing (DST) and some Production tests (PT) during the drilling process. The hose structure is designed to meet the high-temperature and high-pressure acid fluid transportation and operating conditions during the well testing.

• Standard:API Spec 16C

• Hose structure:

Inner carcass: stainless steel carcass;

Internal tube: Particular polymer engineering plastic as inner sealing tube;

Internal rubber liner: HNBR based inner sealing elastomer, which is good for fluid with H2S, oil resistance, corrosion resistance, high temperature resistance, gas permeation resistance; Breaker layer and external protection layer: high tension textile fabric;

Reinforcement for major pressure withstand: high strength steel cable;

Fire shield layer: glass fiber cloth ;

Cover: Neoprene rubber based cover layers, fire resistance, wear resistance, oil resistance, ozone & ageing resistance, UV resistance which is applicable for critical marine environment. 

• Hose passed verification test specified in Clause B12 of API 16C

• Heat trace cable can be assembled by functional requirement

• Different option of external protection layer are available as request or by our recommendation according to operation condition, for example stainless steel armor outer wrap, embedded stainless steel wire in cover, or polyethylene spiral guard, etc.

• Metal connectors: meet NACE MR0175 / ISO 15156 .

• Working temperature range:-25 to +130 ℃ .

• Flexibility specification level: FSL3. 

• Maximum length:70m .

• Length tolerance:Length up to 6.4m, with tolerance ± 64 mm; Length longer than 6.4M with tolerance ± 1％ .

• Measurement basis of Minimum Bending Radius (MBR) is center line of each hose.
